Great! Finally someone explaining how do you 'feel' when your fit is right - and when it is 'not right'. I find this approach the most helpful, much better than formulas.
FINALLY!! a fit video admits there isn't a perfect formula....it's about time! I am an old rider, been riding 10,000 miles a year for 50 years. Today I use 8 different bikes to get a different position every day of the week. Without these changes in bikes and positions I would not be comfortable riding 10,000 a year at 63 years old. So bikes are flat bar, road bar, aero bar // seat tubes at 72, 73 and 74 degrees // handlebar heights different on each // seat height varies by only 1 to 2 millimeters // seat tilt (the most important) varies on all bikes too // Top tube length and stem length vary also from bike to bike. Spine angle to the road varies on each bike from almost vertical to parallel to the road. I practice the main four pedal strokes with variable cadence on all bikes and get to know which is best for all flat rides, rough roads, high winds, all day mountains (no flats). Also get to know which bike to use for a particular workout day; long climbing (10+miles) , time trialing, recovery, long distance, commuting, relaxation low effort soft pedaling....
I couldn't do what you are doing. I have 4 bikes in my rotation and they are so close to each other. The only one that I get a noticeable different ride from is my pilot pedi-cab bike. I have 175 crankset for more torque when weighed down. Otherwise, position is nearly impossible to tell much difference from one bike to the other.
I can listen to this guy talk about bikes and fit all day long. Love your series with him. He is so logical with all his fitting advice. Thanks for sharing his wisdom.
Hey Cam I want to thank you for these fitting videos. I’m 192cm. Changed my stance, cleat position, moved my seat back and shortened my stem. This increased power, eliminated all knee pain, and also ended hand numbness. I feel like I’m just floating on my bike now. Loving the ride. It’s been cool seeing how little adjustments might turn into knee stress on on side or another or change pressure on my hands, and finally getting everything dialed in.
How many millimeters did you shorten the stem? I ended up injured with carpal tunnel... I'm adjusting my bike to be more comfortable, I want to know if shortening the stem from 90 mm to 70 mm harms comfort and control. Thank you
Hi, thank you for your videos. Thanks to you, I was able to adjust the saddle height correctly. I had a problem with my knees and the lower back, although I was doing the specialized bike fit before that. I reduced the height of the saddle and now I have no problems with my lower back and my knees. After I lowered the saddle, I had problems with its forward/backward position. I had ligaments on the back of my knee. For myself, I found a method to find the right fore aft position, I set the saddle as far back as possible, put the bike by the wall and started pedaling in the reverse position. That's how I felt that my ligaments were stretched and strained. I moved the saddle rails 3-4 mm step by step forward until this feeling disappeared. And now I am happy :)
I had a bike fit done by Neill, he is a true professional and you’re right about he explains things. Best money I ever spent on anything cycling related, and I’ve spent a lot 😂
Fascinating stuff. I like how Neil isn't dogmatic about how a bike should be fitted and speaks with lots of good caveats, due to our rather varied physiology and proportions. Though I was puzzled by sorting seat out *after* everything else. To my mind saddle height and position should be set for comfortable pedalling. Only then bar height, tilt etc variations should be set after the saddle position is dialled in. If bars/hoods etc cannot be fitted correctly, then bike is wrong size to start with. I always carefully test ride bikes before buying them and usually the ones I end up with, were comfy from start even without any tweaking, bar my pushing seat back from the usual too forward [for me] position.
Wow wow wow, I played around with this on my ride today and after the third adjustment I found the a sweet spot. It felt so good and I held my cadence in the 90’s while pushing a bigger gear. Thanks so much.
Not sure if this is backed up by Niell, but another good test for saddle set back is if you can ride no-handed. I find that if my saddle is too far forward, too much weight is placed on the front wheel while riding no-handed and it becomes considerably more difficult to do as the wheel wants to grab the road with each pedal stroke. When the saddle is set far enough back, this issue is completely eliminated in my experience.
It only moves an inch. When we were kids we could ride anything with no hands because they had different fork angles that made it easy. Probably still can at 68 years old. I do wobble more than I use to but I can still do it. These seats are not designed for sitting up strait but for riding bent forward.
Hi Cam, very informative video. I just swapped out my Sella Italia SLR Kit Carbonio saddle for the new Fi'zi:k Antares Versus Evo R1 Adaptive Saddle, this is the new 3D printed carbon saddle. It helps spread the support of my sit bones over a larger area and is much more comfortable. However, my hands were hurting and have been for some time now. I realized after watching your video I was pretty far forward on the bike and so I moved it back about 12mm. I'm now much more balanced and my hands feel much much better! I also did a FTP ramp test today and I have not lost any power. Thanks to you and Neill!!!
Not just fore/aft, but also saddle tilt had a big effect on comfort and power output for me. There seems to be a thousand ways to get it wrong, and just one way to get it right.
Great video. If doing your own testing, don't forget that you should also raise the seat post a little as you move the saddle forward and lower it as you move backwards.
the Canadian olympic coaches use to set up our cleats on the pedal with the ball of the lower big toe in line with the peddle axel, then they would get us to move the cranks straight up and down, and then use a string weight plum balm and hold it on the side of the knee cap indentation where the hinge of the legs are on the outside of the leg, the string then lines up with the pedal axel. and you move the seat back and forth to line in up. in that position one can see if the upper pedal leg is too high or flat, adjusting height so your upper leg mussel has a strong and comfortable push down without pressure to the knee, then we last would adjust the handle bar stem length, and that was done by putting your elbow agaist the seat nose, and your 3 longest fingers reached the mid bar.
Some nice explanations you did. And KOPS ....LOL... What I did for last 40+ years of making custom frames (several thousands) is relation between Femur and Tibia. That's some start. For ordinary road bike seat angle (what is literally line from BB Centre to middle of the rails, usually some 160mm from the tip of the saddle (normal saddle that is) is between 71 and 74 degrees. Bigger than 74 increase front load on steep downhills and can be dangerous. What I said for Femur/Tibia is based on muscle structure on those bones, with Femur being bigger, having more of Fast twitch Muscle, rider should go proportionally forward (from middle start of 72.5Deg). We have to take in account that positioning the rider on the saddle is critical for their knee opening, and thus proper "lubrication") Without proper movement knee joint will degrade. Also we must take in account that proper sitting on the saddle is only by - having a saddle contact your body on the bottom of your sitting bones. Anything else is not correct. Rider must feel that area in contact with saddle. If that is achieved padding on the saddle is not necessary (many of new super light saddles). We must take in account also that women are having Sitting Bones higher in their body than a man, thus they tend to get their butt more back, in order to find saddle under those points. I personally adopted 20 years ago to dedust 2.5-3 degrees from "Man's" angle, achieving comfortable position for women. Keep in mind that seat angle is only relation between BB and Saddle. That angle is also based on the purpose of the bike (my first Forward Seat Angle bike in 1981 had 85Deg angle, later making QRoo frames we limited to 76/78 as running is greatly effected by more than that. And remember UCI!!!!!!!!!!) That is a start of my geometry drawing. Everything else is added after. Basically, if you have Seat Angle properly dialed on the frame, saddle will never be moved back or forth.
Wow, KOPS not even considered worth mentioning. Just shows how things have moved on, or how out of touch I am X) Thanks for these, and to Neil for contributing, 5* content
I am so happy I found these videos on this subject. I couldn't figure out why my toes were always numb..Moved my seat forward and changed the angle and omg the difference is night and day!!!
Tri guys had a sliding fore and aft seat post in the early 90's, pitch your seat way forwards for the flats to simulate running and could side back for the hills. Weighed a tonne..... had a cable and lever to release the lock on the seat post... can't remember the make but the shop I was mechanic in catered to tri and everyone wanted or had one...
Cam, just want to say thank you for these fitting video and big thanks to Neil for sharing these information. I had all the symptoms he described; but after watching the saddle height video and read a lot of Steve Hogg's articles, I pretty much eliminate all my issues. This video further confirmed my fore-aft adjustment. I'm now much more comfortable on my bike with higher FTP, Thank you!
How you doing? Thanks for the video! I would also add that setback has some detriment to power output. I don't have a power meter but I have experimented with my SMP by moving it all the way back on its rails and vice versa. Based on perceived effort, setting the saddle too far back seem to have much less weight on the hands but I found it very difficult to push down the pedals especially on the climbs and the pedalling motion feels like I'm 'leaping in circles' and Neil is right - there is a ton of hamstring burn and no quad fatique; there's a lot of heavy breathing and my heartrate seem to be much higher. I do get occasional low back pain on the left side when it was set too far back (maybe due to the a much closed angle and slightly less flexible left hip?) Overall, I just felt like I have to put in more effort to go faster and you're more inclined to grind the gears as opposed to spinning them. On the other end setting the saddle far forward, I feel I can put out more power especially on the climbs with a fully loaded touring bike. My breathing was much more controlled but felt like I was falling forward. Becuase of that, you tend to spin more to counter the effect of falling forward. It may be more powerful however I can't sustain that position on very long rides and your quads are the first to go. I don't get any potential knee issues as someone commented - that can be a factor of cleat positon being too far forward or the saddle too low for a seat that's a little bit far forward (like in a TT positon). I know for SMPs you don't need to adjust the saddle height when you move the seat fore and aft due to the way the rails are angled. I think we can perceive setback as like getting off a chair - put your feet far forward away from the chair and try standing up; it's amazingly difficult. But now, put your feet just in front of the leg of the chair like you always would, you will get off much easier. But if you put your feet way beneath your chair you will most likely fall forward when you try to stand up.
I had the same observations. When I moved to a hilly area from completely flat, everything changed. My back hurt, I got numb toes - all stuff I read about but thought it was just old guys with really bad positions. This year I had the worst back pain and long rides were the worst. I'd go out and ride hard and my quads were never really sore. I'd lower my saddle which temporarily resolved the lower left back pain but it would come back. I decided to get straight seatpost for all my bikes and my cadence speed increased back to what I used to be able to do, my quads are now working better as my legs are build for sprinting with shortish femurs. Of course these changes meant my reach became shorter and my butt wanted to slide back to maintain the previous reach I had been accustomed to. I then bought new longer stems, dropped them lower to get even longer and now descending on the road bike with 73 degree head angle is much, much more stable! The geometry of the bike really does determine how one should be situated on it. Sure I use more upper body strength but that just means I will have more control and work out that core.
Fit is something I have been messing with for the past year or so. When I first started riding I just rode. Then I went into my aero mode which meant that I was getting as low as possible. The problem with that was I was not able to generate power because I was too far forward. Then I realized that I had to be centered in order to maintain good power. I use 3 settings to set my position assuming crank length is correct. 1) Set the seat height with a centered saddle on the rails. Reach for the levers and set where my hands are landing. Fine tune the seat height so that the seat is not cutting into my groin area. 2) Drop the stem to a comfortable height. 3) adjust the setback if you feel like you are a little jammed at the hip. I used this method and it feels like this position seems to be the most comfortable I’ve had yet. What do you think about this method?
Interesting. One thing I don't quite get is that if the balance test is so important, why wouldn't you work out the fore/aft and seat height first and then sort out the cockpit?
If the cockpit is high you are more upright and balance passes everywhere. So you need to know what your back angle and arm extension is before figuring out what seat setback balances that combo.
This a great video. A lot of these guys confuse this subject by making it over complicated. ITs a "feel" for sure. Your body knows more than you think.
Maybe a playlist, setting out the how to's like how to set saddle and seat height then what size handlebars and stem lengths???? So pull them all together for a bike fit series?
Thanks for this. I'm just getting started and I don't have a clue what I'm doing yet. It all feels wrong. I love your dog. Very helpful pup. Maybe that's what I need to get this to fit.
great instructions but the most important point was made at @8:10 with the piano effect. I understand that it was a must and clearly made possible the comprehension wow
I have noticed that when my saddle is too far back, taking off from a stop in a higher gear is hard. Like I can't get over the top of the pedals. Until I scoot forward that is, and at that point it feels good and powerful, and that tells me I need to move my saddle forward. Also, the specific fit on the saddle can make it easier or harder to slide forward and backwards. Since Neil says you want the seat as far forward as possible without overloading the hands, I wonder why he suggests starting by moving it all the way back? I know it's just a starting place, but why not start with it all the way forward, and if you feel quads burning up and too much weight, move it back 5mm, etc..
I think it will be due to how easy it is to spot the contrast on yourself, listening to your own body. Too much weight on hands won't necessarily be apparent in such a short time I suspect.
I just switched to an SMP Vulkor this week (thanks Cam!). It felt fairly good for the first 15 or 20 minutes, then started to hurt a little, then by 90 minutes in, my legs were hurting everywhere down to my calves. I told Coach Colby Pierce about the results, and he suggested changing the seat angle from -5° to -4°. I made that slight change, keeping everything else the same, and the difference was unbelievable. I rode for an hour and not once did I have to move around on the seat at all, in fact I didn't even notice the presence of a saddle under my butt, it was so comfortable it just disappeared. I'm going to go on a 3-hour ride today to confirm the preliminary findings, but just wanted to stress how critical it is that not only are the height and fore-aft positioning critical, but so is the angle. A change of one degree can make a massive difference.
Thank you for an informative video, I am that rider....... Lift weights, physical job, top heavy and suffer from hand numbness. After watching this video, I set my daily ride up on the turbo, even setting my seat right back, I still feel pressure on my hands and can not do the balance thing, is there anything else that I can do? I've looked at setback seat posts, apart from being expensive it would totally spoil the look of my 1978 steel bike. Thank you 😁
fab upload.Went to check my used road bike to find the seat was pushed back to the max,I put it in the middle as a starting point,can already reach the bars easier thanks.
Thanks for the video. My question is, why are the handlebars set all the way down on most modern road bikes? On my retro road bikes, I usually set the saddle and handle bars levels to each other. I found this to be a very comfortable position for long rides with very little muscle fatigue. It appears every modern road bike I see the saddle is way higher than the handle bars and the handle bars are slammed all the way down. Are people riding bikes that are smaller to reduce weight?
Thanks for the valuable content. Neill mentioned sth. about a bad position with the bars either too high or too low. I wonder how Neill would define a bar being in the wrong position. It would be great to have him clarify that. Thanks for making the videos possible. Cheers from Germany
Been debating about getting a bike fit since you started this VLog with Neil, but alas, I don't think I can find someone who is knowledgeable and experienced as he is. I will definitely need to do research before next season. As usual, keep the Neil "knowledge Train" Stanbury coming.
I was getting some disturbing numbness in the nether regions within 10 to 20 minutes of starting my ride. I changed my seat height and position and the numbness went away. I may still not be in the "perfect" position but this adjustment has allowed me to start enjoying my rides once again. Thanks!
The last minute or so is very interesting. I remember finding a forward position that was amazing for climbing power using my quads when I was in the mountains for a few days once. But have never understood why it feels so awful when on the flat for hours. I get it now - thanks!
Cam, I know these videos are in the RCA Training Tips Show Playlist on your TH-cam channel. For the benefit everyone who has been following this amazing video series, and the fact that people like me are probably re-watching these videos multiple times, might it warrant its own separate playlist?
Thanks a lot. Sounds super plausible and 100% confirms my feelings over the years. Unfortunately I am still experimenting in finding an optimal position for long alpine Mountain Biking. Any professional advice here for let's assume an 8 hour Marathon, from which almost 6hours is 8..18% steep uphill of 45-60min duration each, the rest is level or downhill. Compared to "flat road and race bike theory": How to adjust position for this case? Certainly more to front. How much? How to adjust seat angle? Certainly nose down. How much? Which of the 2 is the better parameter to start trial & error with? Thank you!
Neil actually knows what he's doing, kudos for not pushing KOPS. Why do so many other "professional" bike fitters keep using KOPS as a fitting metric? It was never supposed to be a fitting metric since your knee will wind up over the pedal spindle at some point in your stroke. KOPS is a bike sizing holdover from when road bike frames all had the same basic shape with a flat top tube and came in 1 or 2 cm size increments. It was always just a quick metric to check if you were on the right size frame within a size up, down, or middle of your range, not a setup/bike fitting metric. I'm starting to think that a lot of bike fitters out there are the chiropractors of cycling, every time I see one center a saddle position, and a crankset setup around KOPS.
Cam thanks for a great channel and videos. I find it very interesting and cool that there's a group of fitters and frame builders that have been fitting cyclists in generally similar ways for a number of years. From your fitter Neil, his mentor Steve Hogg, to various frame builders here in the US and I'm sure other parts of the world Keith Bontrager, Ben Serotta, Dave Kirk, etc. ALL these guys and I know more really have it down when it comes to fitting as well as other cycling aspects.
Hey. Correct me if I’m wrong but maybe we should start by setting up your saddle height and the saddle position first using the no hand balance technique and the 3mm increment over 20 min. And then once this is done, set the bars and reach with the minimum hand pressure
this advice is mostly for someone who is doing 50 miles or so, more a week. if you are a weekend warrior, you should be fine. it is when you start really getting into it, that you need to learn more, cause you are on the bike for much longer, time wise, 1 hr, 2hr., i just did 61 miles in 4 hrs, this is when all this info comes into play. Don't quit, just realize, this is the same with everything. in the begining, i used to read articles about things like the feel of the road etc., i could not detect such things, now 7000 miles later, and a bike upgrade, I DEFINITELY KNOW WHAT THEY ARE TALLKING ABOUT.
Regarding Bicycle Seat Maintenance: Any info/Products regarding "proactive maintenance" of SYNTHETIC LEATHERS (i.e. aging, weathering or stress cracking). I realize it's nonporous and guess it's "material quality" specific but how to generally keep it as pliable and soft as possible over time if possible.
Curious. I live in the French Alps and ride almost no flats, ever. Almost no road is any less than a +/- 3% slope (depending on whether you’re going up or down 😁). Downhill is easily managed, just compensate by sliding back on the seat - which I do anyway to improve my tuck. But based on what Neill said towards the end of the video, that a 1 degree incline equates to a 10mm rearward pelvis position, plus further forward pelvis rotation to compensate, should my saddle be set more ‘fore’ than neutral. I’m a powerfully built rider with low flexibility and notice a huge amount of hip flexor and lower back fatigue on climbs, many of which are 7% average of 10-15kms……just wondering if adapting the position would be worthwhile, with a more neutral position chosen when we’re on holiday doing ‘rolling’ terrain?
Man. Neill is some kind of seat whisperer. But that's passion. This is what science is all about. Not one BS claim out of this guy, he backed it all up with logic.
Great info! I've always struggled with saddle position while trying to not load the bars too much and also not go numb from too much pressure despite riding on my pelvic bones - I evenutally transitioned to an ISM split saddle (common for Triathletes) to avoid excess perineal pressure butt it's not ideal. I've tried several trough-style saddles to no avail but seeing this, I will experiment a bit more. Thanks.
After watching this I am further forward than ever before. I am running a 0 setback post and I am a little more than midway forward on my rails. The last time I was "fit" my seat was about 69mm behind the BB center. Now I am closer to 50.....Feels good over all but after a longer ride I get a light soreness in my patella tendon next day. Seat height feels good. 20mm seems like a big jump so perhaps some time is needed.
@@CamNicholls thanks. During yesterdays 60 mile gravel ride I found the sweet spot. I think my HB height may need to come up 5mm to compensate but my seat feels spot on height and fore/aft.
Interesting no talk of perineal issues, which I feel like I noticed when my seat was too far back. Instead of sitting back and extending my reach I would just sit on the nose of the saddle and cause too much pressure there. I wonder what Neil would advise then for setting bar distance. I've always leaned towards bringing my saddle further forward and my bars closer, but I'm still having issues I'm trying to sort out so.... For me bike discomfort and therefore bike fit is probably the main thing that saps my enjoyment from cycling.
Question : if you were to be able to measure the weight distribution between rear and front wheel, wouldn’t that be a way to establish the best position on the bike? Dunno, just asking...
Thanks again for these fitment videos, really helped in understanding what my legs were trying to tell me. I'm re building a base fitness (casual rider) and passed most aches of as, you just unfit suck it up. Great guide and conversation.
A racer or casual rider should feel comfortable in the saddle. "Comfortable " is relative to the final position desired. Either way; you should feel good/comfortable on your bike. I hope you find that happy position 🙂. You will know it when you get it. You feel as if you are floating on your bike.
He is right about as far forward before too much hand pain. It really is an experiment, you will also have more power with the seat further ahead and cleats all the way back.
The last part of him talking about the saddle angle in relation to BB changing dynamically as the road undulates, are we presupposing the rider will be riding on level ground more therefore setback is established on level ground? If you’re a rider who spends their rides ascending 100ft/mile would it better to set the saddle for that?
I certainly ride with my saddle set up for at least a slight angle forward and less setback because i end up spending so much time riding uphill and got used to it in all situations
The Vertex Fit Cycle is the only fit platform that completely isolates saddle setback (effective seat angle) from the rest of the bike fit web. You can sweep it through a huge range of setback while rider works under load yet without altering distance to pedals, bars, drop, etc. You should check it out.
Amazing stuff but one thing i wish he'd have adressed is how i tend to compensate saddle for/aft changing by sitting differently on my saddle which makes it even tougher to address properly.
7:40 "Do the balance test when you're riding 20 minutes effort" ⇒ I understand it in the way that you *don't have* to ride this test for 20 minutes, it's just push your pedals for a few minutes but with Watts similar to your FTP. Am I right? Regards!
There's more to saddle set back than discussed here. Spinal flexibility and low back pathology Hip joint morphology (FAI) Leg length discrepancy Iliac artery morphology and effect of increased hip jt angle. (risk of iliac artery endofibrosus or compromised venous return) Respiratory efficiency - chest expansion, diaphragmatic excursion. Abdominal congestion/comfort Injuries carried Aerodynamics improvement by lower back angle and elongated upper limbs Rider center of gravity and its influence on steering and braking control (especially relative to avoiding speed wobble) Cadence efficiency and comfort Endurance vs sprint power Optimal saddle height and setback, and stem height/length are reached after consideration of which of the above are being prioritized. In grand tours some riders adjust saddle position based on terrain and role within the team. I was surprised to hear Neill confounding saddle setback with stem position. Saddle height and setback are better determined prior to and independent of stem location. Neill's views expressed here don't account for why most GC riders use a bike frame one size below recommended by the manufacturer.
Working with my girlfriend on this recently. I know this sounds very novice but teaching people how to sit on the saddle first is critical. Too many new riders do not understand where the contact point is supposed to be and there is serious discomfort or injury caused by it.
Where is the contact point supposed to be? I tend to slowly slide forward to the nose of saddle as I pedal, then push my butt back to get the sitbones on the wider part of the saddle again. This keeps repeating. Not sure if it's about saddle fore/aft or saddle tilt, or other
Thanks for the great video. In listening to what Neill has to say re determining position when under load (close to FTP), what about a scenario like very long distance rides (300k+) where you are not putting out anything near FTP on average. Should setback be different as you aren't putting out the same forces to offload your hands?? Specific example here is a 200 mile gravel ride. Thanks!!
I adjusted my saddle position forward until it felt right. Consequently I measured my 45 year old road bike which is like an old shoe. My new Cannondale Topstone L size wound up with identical saddle nose to center of the hoods dimension. The classic with 40mm shallow drop bars, the Topstone with wide gravel drop bars. The nose to center of bb dimension is also identical. The saddle height is identical. The Topstone has a more relaxed seat tube angle, and would be about a 57cm bike, The Dave Moulton is a very steep angled bike with a short top tube, and would be about a 53cm by most measurement standards. The only measurement consciously selected was the saddle height. Short leg length, long torso and arms. The sloping top tube allowed the L frame to have straddle height. It's amazing bikes from vastly different eras can fit comfortably, and ride so differently. Also my aluminum track bike feels great in a different way, but with vastly different handling ( razor sharp), and similar to that on the body after 100km!😂
Greetings from UK, I hope you're doing well over there with all this Covid_19 BS right now. Another brilliant video, by far the best on this topic I've come across. Thanks to Neil as well obviously. Safe riding 👍
@Wooly Chewbakker You're reading it incorrectly. I don't believe the disease is BS, but I believe the media carry on and the way Govts are reacting to it is BS. People die every year of all sorts of illnesses including bad flu seasons that kill hundreds of thousands. However, COVID-19 is used as fear-mongering clickbait by the media and used to political advantage by Govts, rather than really carrying about the community as a whole.
I'm 6'4 on a 60cm cyclocross bike that I use for gravel and road biking... they have slightly different geometry from a strict road bike... I find myself never being able to find a true/perfect position. I'd say my limb lengths, torso lengths are all proportionate (in other words, I'm not 6'4 with long arms/legs short torso, or short legs long torso... I'm proportionate). In order to get full leg extension... I extend my seat post fully at its limit. Maybe 1cm passed it actually. Not only that, but I have to slide my saddle all the way back for a bit more leg extension, and reach (Since if I keep the saddle neutral or forward, I feel cramped up front). I even have a 110mm long stem. The position this puts me in.. gives me a feeling of kicking forward while my femur bones are too close to my torso (which doesn't allow me to put out as much power... although it puts me in a more aero position). Issue is... If I shorten the stem... I'm cramped. If I slide seat foward... I'm cramped. If I slide seat post down... legs don't get extension. I think I've come to the conclusion that my frame just isn't enough for me... Gotta go full road bike, maybe a 61cm. Thoughts from anyone? Looking for all the ideas I can get...
Thanks for another great bike fitting video. As Neill put, one thing changed can affect others. So what is the correct sequence to adjust the whole bike setting? Saddle height -> fore-aft -> cleat -> bar?
Hey...I'm not going to sweat the details. Right or wrong I'm comfortable with my current position. If I bought a new frame then I may revisit my saddle position.
Hi good stuff. What would you recommend for a forward crank cruiser type bike where you sit straight up? I ride hard and about 40-50 miles a day. Currently has the big padded seat which is terrible. Is my bike bad with the forward set cranks besides being inefficient and seat being far back? Thanks
Hey, thanks for these videos, it's a great source of knowledge ! One question, I found myself want to sit far back on the saddle in order to get the full muscles working correctly and to get that feel of pedaling in circles. How should I set my saddle to stop that need to slide back ? If I move it forward, I'll only exagerate the issue where I feel the need to slide back. I dont know wether I should move it back, up or set the cleats further forward to the front of the shoes. If you have any tips on this, thank you.
cleats all the way back and heels at 5 o'clock pedal position without any shoes on. I'm a nobody but you can try this for comfortable ride🤷♂️ it works in My case
I've heard of another bike fit quick tip on saddle fore and aft. Pedal at a cadence below threshold (ex95-105 is my face pace, pedal at around 80ish). Let go of the bars and pull your upper body up, too much core involvement, or a significant increase in cadence indicates your saddle position is incorrect. Usually an indicator of too far forward. This is also assuming you've got all the other variables correct.
I’m 6’ 4” tall and manufacturers have always recommended 60cm frame size for me. I have two bikes at this size but have generally felt a bit too stretched out even with a shorter stem. A year ago I decided to buck the advice of the manufacturer and bought a 58cm Cannondale Synapse which feels a lot better for me. Even so, having followed Neil’s earlier advice regarding the balance test I still find my saddle needs to be as far back as the seat post will allow to pass the balance test and not slide forwards on the saddle. This is with a 15mm setback seat post as well and something that is also not touched upon in these videos i.e. seat post setback. I’ve shortened my stem down to 100mm as well and it’s not slammed either but my position on the bike does feel a lot better. I’ve ordered 165mm cranks as well because I do have some hip impingement due to a couple of accidents in the past. That will obviously put the saddle up a bit as well. Bottom line is even with the smaller bike, saddle right back and shorter stem I still feel like I am not totally nailing the balance test without sliding forwards on the saddle a bit when pedalling. I’m not sure where I can go from here. On my 60cm bikes (Scott CR1 so not race bikes) it basically is what it is. I’ve gone as far as I can with those and just have to accept that maybe they are too big for me.
I am 6’3”, 170lbs. I always have a very hard time doing the balance test. I’m going to go ahead and call BS on the balance test. I don’t think it works for all body types, especially tall guys like us.
I am 190cm and I also ride with the saddle nearly all the way back. I tried to move it forward but it didn't feel good, so I pushed it back again. So maybe there is nothing wrong with it :)
Great! Finally someone explaining how do you 'feel' when your fit is right - and when it is 'not right'. I find this approach the most helpful, much better than formulas.
I also mean that in terms of muscle recruitment. Understanding this is most essential.
🤣🤣🤣🤣
FINALLY!! a fit video admits there isn't a perfect formula....it's about time! I am an old rider, been riding 10,000 miles a year for 50 years. Today I use 8 different bikes to get a different position every day of the week. Without these changes in bikes and positions I would not be comfortable riding 10,000 a year at 63 years old. So bikes are flat bar, road bar, aero bar // seat tubes at 72, 73 and 74 degrees // handlebar heights different on each // seat height varies by only 1 to 2 millimeters // seat tilt (the most important) varies on all bikes too // Top tube length and stem length vary also from bike to bike. Spine angle to the road varies on each bike from almost vertical to parallel to the road. I practice the main four pedal strokes with variable cadence on all bikes and get to know which is best for all flat rides, rough roads, high winds, all day mountains (no flats). Also get to know which bike to use for a particular workout day; long climbing (10+miles) , time trialing, recovery, long distance, commuting, relaxation low effort soft pedaling....
I couldn't do what you are doing. I have 4 bikes in my rotation and they are so close to each other. The only one that I get a noticeable different ride from is my pilot pedi-cab bike. I have 175 crankset for more torque when weighed down. Otherwise, position is nearly impossible to tell much difference from one bike to the other.
@@fernandovega5722 I can tell if the seat post height has been moved just 2mm.
I can listen to this guy talk about bikes and fit all day long. Love your series with him. He is so logical with all his fitting advice. Thanks for sharing his wisdom.
Hey Cam I want to thank you for these fitting videos. I’m 192cm. Changed my stance, cleat position, moved my seat back and shortened my stem. This increased power, eliminated all knee pain, and also ended hand numbness. I feel like I’m just floating on my bike now. Loving the ride. It’s been cool seeing how little adjustments might turn into knee stress on on side or another or change pressure on my hands, and finally getting everything dialed in.
Yes truly
Awesome stuff, Mark. Thanks for sharing on the thread
How many millimeters did you shorten the stem? I ended up injured with carpal tunnel... I'm adjusting my bike to be more comfortable, I want to know if shortening the stem from 90 mm to 70 mm harms comfort and control. Thank you
Hi, thank you for your videos. Thanks to you, I was able to adjust the saddle height correctly. I had a problem with my knees and the lower back, although I was doing the specialized bike fit before that. I reduced the height of the saddle and now I have no problems with my lower back and my knees.
After I lowered the saddle, I had problems with its forward/backward position. I had ligaments on the back of my knee. For myself, I found a method to find the right fore aft position, I set the saddle as far back as possible, put the bike by the wall and started pedaling in the reverse position. That's how I felt that my ligaments were stretched and strained. I moved the saddle rails 3-4 mm step by step forward until this feeling disappeared. And now I am happy :)
Great to see Neill here! I was fortunate enough to work with him on my bike fit a few years ago and he is an absolute legend. Best money I ever spent.
Neill is amazing. Sounds like your best friend explaining something to you.
Agree. Enjoyment to listen him explaining stuff someone would charge you hundreds...
This foo is awesome as fuck. Intelligence and good vibes.
damn! I need new friends.. all mine does is influence me to do bad stuff 🤣
I had a bike fit done by Neill, he is a true professional and you’re right about he explains things. Best money I ever spent on anything cycling related, and I’ve spent a lot 😂
You're clearly not Australian
Fascinating stuff. I like how Neil isn't dogmatic about how a bike should be fitted and speaks with lots of good caveats, due to our rather varied physiology and proportions.
Though I was puzzled by sorting seat out *after* everything else. To my mind saddle height and position should be set for comfortable pedalling. Only then bar height, tilt etc variations should be set after the saddle position is dialled in. If bars/hoods etc cannot be fitted correctly, then bike is wrong size to start with.
I always carefully test ride bikes before buying them and usually the ones I end up with, were comfy from start even without any tweaking, bar my pushing seat back from the usual too forward [for me] position.
Wow wow wow, I played around with this on my ride today and after the third adjustment I found the a sweet spot. It felt so good and I held my cadence in the 90’s while pushing a bigger gear. Thanks so much.
Awesome to hear, thanks for sharing Rodney
Not sure if this is backed up by Niell, but another good test for saddle set back is if you can ride no-handed. I find that if my saddle is too far forward, too much weight is placed on the front wheel while riding no-handed and it becomes considerably more difficult to do as the wheel wants to grab the road with each pedal stroke. When the saddle is set far enough back, this issue is completely eliminated in my experience.
It only moves an inch. When we were kids we could ride anything with no hands because they had different fork angles that made it easy. Probably still can at 68 years old. I do wobble more than I use to but I can still do it. These seats are not designed for sitting up strait but for riding bent forward.
YESSS i am with u on this one… i feel exactly the same !
I'm going to give that a go on my next ride.
Neil is absolutely brilliant with his analysis. I'm learning quite a bit and will be getting a bike fitting soon. Good stuff!
I've struggled with the fore-aft issue for over a decade, this is the best explanation I've ever heard.
Hi Cam, very informative video. I just swapped out my Sella Italia SLR Kit Carbonio saddle for the new Fi'zi:k Antares Versus Evo R1 Adaptive Saddle, this is the new 3D printed carbon saddle. It helps spread the support of my sit bones over a larger area and is much more comfortable. However, my hands were hurting and have been for some time now. I realized after watching your video I was pretty far forward on the bike and so I moved it back about 12mm. I'm now much more balanced and my hands feel much much better! I also did a FTP ramp test today and I have not lost any power. Thanks to you and Neill!!!
Very practical, yet very scientific. I will apply what I've learned this weekend and throughout the week to find the best saddle position. Thank you.
Not just fore/aft, but also saddle tilt had a big effect on comfort and power output for me. There seems to be a thousand ways to get it wrong, and just one way to get it right.
Great video explaining the physics happening during saddle fore-and-after placement. The balance test is really great and helped me a lot.
Took a while for it all to sink in but I got it dialed in now. Thanks a lot.
Great video. If doing your own testing, don't forget that you should also raise the seat post a little as you move the saddle forward and lower it as you move backwards.
the Canadian olympic coaches use to set up our cleats on the pedal with the ball of the lower big toe in line with the peddle axel, then they would get us to move the cranks straight up and down, and then use a string weight plum balm and hold it on the side of the knee cap indentation where the hinge of the legs are on the outside of the leg, the string then lines up with the pedal axel. and you move the seat back and forth to line in up. in that position one can see if the upper pedal leg is too high or flat, adjusting height so your upper leg mussel has a strong and comfortable push down without pressure to the knee, then we last would adjust the handle bar stem length, and that was done by putting your elbow agaist the seat nose, and your 3 longest fingers reached the mid bar.
Some nice explanations you did. And KOPS ....LOL...
What I did for last 40+ years of making custom frames (several thousands) is relation between Femur and Tibia.
That's some start.
For ordinary road bike seat angle (what is literally line from BB Centre to middle of the rails, usually some 160mm from the tip of the saddle (normal saddle that is) is between 71 and 74 degrees. Bigger than 74 increase front load on steep downhills and can be dangerous.
What I said for Femur/Tibia is based on muscle structure on those bones, with Femur being bigger, having more of Fast twitch Muscle, rider should go proportionally forward (from middle start of 72.5Deg).
We have to take in account that positioning the rider on the saddle is critical for their knee opening, and thus proper "lubrication") Without proper movement knee joint will degrade.
Also we must take in account that proper sitting on the saddle is only by - having a saddle contact your body on the bottom of your sitting bones. Anything else is not correct. Rider must feel that area in contact with saddle. If that is achieved padding on the saddle is not necessary (many of new super light saddles).
We must take in account also that women are having Sitting Bones higher in their body than a man, thus they tend to get their butt more back, in order to find saddle under those points. I personally adopted 20 years ago to dedust 2.5-3 degrees from "Man's" angle, achieving comfortable position for women.
Keep in mind that seat angle is only relation between BB and Saddle.
That angle is also based on the purpose of the bike (my first Forward Seat Angle bike in 1981 had 85Deg angle, later making QRoo frames we limited to 76/78 as running is greatly effected by more than that. And remember UCI!!!!!!!!!!)
That is a start of my geometry drawing. Everything else is added after.
Basically, if you have Seat Angle properly dialed on the frame, saddle will never be moved back or forth.
Wow, KOPS not even considered worth mentioning. Just shows how things have moved on, or how out of touch I am X) Thanks for these, and to Neil for contributing, 5* content
I am so happy I found these videos on this subject. I couldn't figure out why my toes were always numb..Moved my seat forward and changed the angle and omg the difference is night and day!!!
I had No idea as to how technical and detailed this sport was !! I’m still madly Loving it ! Getting out there and crushing the Km ‘s. !!!
Tri guys had a sliding fore and aft seat post in the early 90's, pitch your seat way forwards for the flats to simulate running and could side back for the hills. Weighed a tonne..... had a cable and lever to release the lock on the seat post... can't remember the make but the shop I was mechanic in catered to tri and everyone wanted or had one...
Think I’m going to quit this hobby as setting a bike up sounds like an application at nasa
Don't let the nerdier cyclists spook ya! Experiment.
😂😂😂😂
Get a unicycle! Much easier to set up!
Skill issue
It can be very frustrating if you're constantly doubting the setting 🐢
Great video mate, your bike fit series has to be the best in TH-cam!
Cam, just want to say thank you for these fitting video and big thanks to Neil for sharing these information. I had all the symptoms he described; but after watching the saddle height video and read a lot of Steve Hogg's articles, I pretty much eliminate all my issues. This video further confirmed my fore-aft adjustment. I'm now much more comfortable on my bike with higher FTP, Thank you!
Good stuff mate, thanks for sharing on the thread.
Love the image of The Badger on the piano. Thank you for sharing your skills Neil!
How you doing? Thanks for the video! I would also add that setback has some detriment to power output. I don't have a power meter but I have experimented with my SMP by moving it all the way back on its rails and vice versa. Based on perceived effort, setting the saddle too far back seem to have much less weight on the hands but I found it very difficult to push down the pedals especially on the climbs and the pedalling motion feels like I'm 'leaping in circles' and Neil is right - there is a ton of hamstring burn and no quad fatique; there's a lot of heavy breathing and my heartrate seem to be much higher. I do get occasional low back pain on the left side when it was set too far back (maybe due to the a much closed angle and slightly less flexible left hip?) Overall, I just felt like I have to put in more effort to go faster and you're more inclined to grind the gears as opposed to spinning them.
On the other end setting the saddle far forward, I feel I can put out more power especially on the climbs with a fully loaded touring bike. My breathing was much more controlled but felt like I was falling forward. Becuase of that, you tend to spin more to counter the effect of falling forward. It may be more powerful however I can't sustain that position on very long rides and your quads are the first to go. I don't get any potential knee issues as someone commented - that can be a factor of cleat positon being too far forward or the saddle too low for a seat that's a little bit far forward (like in a TT positon). I know for SMPs you don't need to adjust the saddle height when you move the seat fore and aft due to the way the rails are angled.
I think we can perceive setback as like getting off a chair - put your feet far forward away from the chair and try standing up; it's amazingly difficult. But now, put your feet just in front of the leg of the chair like you always would, you will get off much easier. But if you put your feet way beneath your chair you will most likely fall forward when you try to stand up.
Thanks for against on the thread Stefan, interesting to hear
I think thats in relation already as Neil mentioned the effect of it specially on climbing👌
I had the same observations. When I moved to a hilly area from completely flat, everything changed. My back hurt, I got numb toes - all stuff I read about but thought it was just old guys with really bad positions.
This year I had the worst back pain and long rides were the worst. I'd go out and ride hard and my quads were never really sore. I'd lower my saddle which temporarily resolved the lower left back pain but it would come back.
I decided to get straight seatpost for all my bikes and my cadence speed increased back to what I used to be able to do, my quads are now working better as my legs are build for sprinting with shortish femurs.
Of course these changes meant my reach became shorter and my butt wanted to slide back to maintain the previous reach I had been accustomed to. I then bought new longer stems, dropped them lower to get even longer and now descending on the road bike with 73 degree head angle is much, much more stable! The geometry of the bike really does determine how one should be situated on it. Sure I use more upper body strength but that just means I will have more control and work out that core.
Fit is something I have been messing with for the past year or so. When I first started riding I just rode. Then I went into my aero mode which meant that I was getting as low as possible. The problem with that was I was not able to generate power because I was too far forward. Then I realized that I had to be centered in order to maintain good power. I use 3 settings to set my position assuming crank length is correct. 1) Set the seat height with a centered saddle on the rails. Reach for the levers and set where my hands are landing. Fine tune the seat height so that the seat is not cutting into my groin area. 2) Drop the stem to a comfortable height. 3) adjust the setback if you feel like you are a little jammed at the hip. I used this method and it feels like this position seems to be the most comfortable I’ve had yet. What do you think about this method?
Interesting. One thing I don't quite get is that if the balance test is so important, why wouldn't you work out the fore/aft and seat height first and then sort out the cockpit?
You falsely pass the balance test with a low, far back saddle. That was my experience at least.
If the cockpit is high you are more upright and balance passes everywhere. So you need to know what your back angle and arm extension is before figuring out what seat setback balances that combo.
Yeah, this bike fitting series with Neill is incredible! Thank you so much. I'm learning lots.
This a great video. A lot of these guys confuse this subject by making it over complicated. ITs a "feel" for sure. Your body knows more than you think.
thank you for this long running primer on the many 'hows' of bike fitting. awesome.
Maybe a playlist, setting out the how to's like how to set saddle and seat height then what size handlebars and stem lengths???? So pull them all together for a bike fit series?
Thanks for this. I'm just getting started and I don't have a clue what I'm doing yet. It all feels wrong. I love your dog. Very helpful pup. Maybe that's what I need to get this to fit.
great instructions but the most important point was made at @8:10 with the piano effect. I understand that it was a must and clearly made possible the comprehension wow
I have noticed that when my saddle is too far back, taking off from a stop in a higher gear is hard. Like I can't get over the top of the pedals. Until I scoot forward that is, and at that point it feels good and powerful, and that tells me I need to move my saddle forward. Also, the specific fit on the saddle can make it easier or harder to slide forward and backwards.
Since Neil says you want the seat as far forward as possible without overloading the hands, I wonder why he suggests starting by moving it all the way back? I know it's just a starting place, but why not start with it all the way forward, and if you feel quads burning up and too much weight, move it back 5mm, etc..
I think it will be due to how easy it is to spot the contrast on yourself, listening to your own body. Too much weight on hands won't necessarily be apparent in such a short time I suspect.
I just switched to an SMP Vulkor this week (thanks Cam!). It felt fairly good for the first 15 or 20 minutes, then started to hurt a little, then by 90 minutes in, my legs were hurting everywhere down to my calves. I told Coach Colby Pierce about the results, and he suggested changing the seat angle from -5° to -4°. I made that slight change, keeping everything else the same, and the difference was unbelievable. I rode for an hour and not once did I have to move around on the seat at all, in fact I didn't even notice the presence of a saddle under my butt, it was so comfortable it just disappeared. I'm going to go on a 3-hour ride today to confirm the preliminary findings, but just wanted to stress how critical it is that not only are the height and fore-aft positioning critical, but so is the angle. A change of one degree can make a massive difference.
Interesting to hear mate, thanks for sharing on the thread. Cam
How did you calculate the seat angle?
hi, you may use an app in iphone to measure it
Thank you for an informative video, I am that rider....... Lift weights, physical job, top heavy and suffer from hand numbness. After watching this video, I set my daily ride up on the turbo, even setting my seat right back, I still feel pressure on my hands and can not do the balance thing, is there anything else that I can do? I've looked at setback seat posts, apart from being expensive it would totally spoil the look of my 1978 steel bike.
Thank you 😁
this is gold content!!! cant believe is for free here on yt
Read my mind, this was my #1 question for Neil. Awesome explanation. Now I need a shorter stem 😳😅Thanks for posting!
fab upload.Went to check my used road bike to find the seat was pushed back to the max,I put it in the middle as a starting point,can already reach the bars easier thanks.
Great video. I had it way too far back causing me a lot of frontal knee pain. Moving it forward seems to have solved the issue.
So much information to digest again. And still it all makes senses.
Thanks for the video. My question is, why are the handlebars set all the way down on most modern road bikes? On my retro road bikes, I usually set the saddle and handle bars levels to each other. I found this to be a very comfortable position for long rides with very little muscle fatigue. It appears every modern road bike I see the saddle is way higher than the handle bars and the handle bars are slammed all the way down. Are people riding bikes that are smaller to reduce weight?
Thanks for the valuable content.
Neill mentioned sth. about a bad position with the bars either too high or too low. I wonder how Neill would define a bar being in the wrong position. It would be great to have him clarify that.
Thanks for making the videos possible.
Cheers from Germany
Very new cyclist here, I really enjoy this channels content!
Thanks for sharing mate 👍
I want to visit Australia just to meet him
Been debating about getting a bike fit since you started this VLog with Neil, but alas, I don't think I can find someone who is knowledgeable and experienced as he is. I will definitely need to do research before next season.
As usual, keep the Neil "knowledge Train" Stanbury coming.
good reference when i build up my bike, gotta fine tune my position. thanks for the easy to digest info.
Enjoy the build 👍✅
I was getting some disturbing numbness in the nether regions within 10 to 20 minutes of starting my ride. I changed my seat height and position and the numbness went away. I may still not be in the "perfect" position but this adjustment has allowed me to start enjoying my rides once again. Thanks!
The last minute or so is very interesting. I remember finding a forward position that was amazing for climbing power using my quads when I was in the mountains for a few days once. But have never understood why it feels so awful when on the flat for hours. I get it now - thanks!
Thank you two-this series has been really helpful and validating as I have been working with my own positioning on the bike. Keep them coming!
This was the video I was finding for a long time. Thank you so much for making a video on this topic
Forward saddle as my starting point since I have a shorter arm reach, and gradually adjust my saddle height up/down till i get comfortable.
Cam,
I know these videos are in the RCA Training Tips Show Playlist on your TH-cam channel. For the benefit everyone who has been following this amazing video series, and the fact that people like me are probably re-watching these videos multiple times, might it warrant its own separate playlist?
Yes, I have actually been meaning to get to that! The LIST is large when you're a sole trader, but I will prioritise it! Cam
I don’t know whether I should swap stem for something slightly longe or adjust saddle first. Advice please
Thanks a lot. Sounds super plausible and 100% confirms my feelings over the years. Unfortunately I am still experimenting in finding an optimal position for long alpine Mountain Biking.
Any professional advice here for let's assume an 8 hour Marathon, from which almost 6hours is 8..18% steep uphill of 45-60min duration each, the rest is level or downhill.
Compared to "flat road and race bike theory":
How to adjust position for this case? Certainly more to front. How much?
How to adjust seat angle? Certainly nose down. How much?
Which of the 2 is the better parameter to start trial & error with?
Thank you!
Like the paint at the end lol. Playing piano on the bars love it n
Neil actually knows what he's doing, kudos for not pushing KOPS. Why do so many other "professional" bike fitters keep using KOPS as a fitting metric? It was never supposed to be a fitting metric since your knee will wind up over the pedal spindle at some point in your stroke. KOPS is a bike sizing holdover from when road bike frames all had the same basic shape with a flat top tube and came in 1 or 2 cm size increments. It was always just a quick metric to check if you were on the right size frame within a size up, down, or middle of your range, not a setup/bike fitting metric. I'm starting to think that a lot of bike fitters out there are the chiropractors of cycling, every time I see one center a saddle position, and a crankset setup around KOPS.
Big help establishing my seat position. Thank you. Explained very well
Cam thanks for a great channel and videos. I find it very interesting and cool that there's a group of fitters and frame builders that have been fitting cyclists in generally similar ways for a number of years. From your fitter Neil, his mentor Steve Hogg, to various frame builders here in the US and I'm sure other parts of the world Keith Bontrager, Ben Serotta, Dave Kirk, etc. ALL these guys and I know more really have it down when it comes to fitting as well as other cycling aspects.
👍
Where you sit depends on what music you play on your piano.
😂😂😂
I.m 5\11 with long arms I'm riding a vintage Schwinn world sport, your video was very helpful" thanks much man🤟🚴🤙👍
Hey. Correct me if I’m wrong but maybe we should start by setting up your saddle height and the saddle position first using the no hand balance technique and the 3mm increment over 20 min. And then once this is done, set the bars and reach with the minimum hand pressure
What about sest fore/aft for a TT/tri bike?
this advice is mostly for someone who is doing 50 miles or so, more a week. if you are a weekend warrior, you should be fine. it is when you start really getting into it, that you need to learn more, cause you are on the bike for much longer, time wise, 1 hr, 2hr., i just did 61 miles in 4 hrs, this is when all this info comes into play. Don't quit, just realize, this is the same with everything. in the begining, i used to read articles about things like the feel of the road etc., i could not detect such things, now 7000 miles later, and a bike upgrade, I DEFINITELY KNOW WHAT THEY ARE TALLKING ABOUT.
Regarding Bicycle Seat Maintenance:
Any info/Products regarding "proactive maintenance" of SYNTHETIC LEATHERS (i.e. aging, weathering or stress cracking). I realize it's nonporous and guess it's "material quality" specific but how to generally keep it as pliable and soft as possible over time if possible.
Curious. I live in the French Alps and ride almost no flats, ever. Almost no road is any less than a +/- 3% slope (depending on whether you’re going up or down 😁). Downhill is easily managed, just compensate by sliding back on the seat - which I do anyway to improve my tuck. But based on what Neill said towards the end of the video, that a 1 degree incline equates to a 10mm rearward pelvis position, plus further forward pelvis rotation to compensate, should my saddle be set more ‘fore’ than neutral. I’m a powerfully built rider with low flexibility and notice a huge amount of hip flexor and lower back fatigue on climbs, many of which are 7% average of 10-15kms……just wondering if adapting the position would be worthwhile, with a more neutral position chosen when we’re on holiday doing ‘rolling’ terrain?
These vids are EXTREMELY helpful. Thank you!
Man. Neill is some kind of seat whisperer. But that's passion. This is what science is all about. Not one BS claim out of this guy, he backed it all up with logic.
Great info! I've always struggled with saddle position while trying to not load the bars too much and also not go numb from too much pressure despite riding on my pelvic bones - I evenutally transitioned to an ISM split saddle (common for Triathletes) to avoid excess perineal pressure butt it's not ideal. I've tried several trough-style saddles to no avail but seeing this, I will experiment a bit more. Thanks.
After watching this I am further forward than ever before. I am running a 0 setback post and I am a little more than midway forward on my rails. The last time I was "fit" my seat was about 69mm behind the BB center. Now I am closer to 50.....Feels good over all but after a longer ride I get a light soreness in my patella tendon next day. Seat height feels good. 20mm seems like a big jump so perhaps some time is needed.
Interesting to hear, thanks for sharing on the thread
@@CamNicholls thanks. During yesterdays 60 mile gravel ride I found the sweet spot. I think my HB height may need to come up 5mm to compensate but my seat feels spot on height and fore/aft.
I have a compressed disc, leaning forward is very painful. Trying to find proper settings while keeping a vertical spine position is very difficult.
Buy a hanging bar..and just hang for 1 minute 5 or 10 times a day.... it will improve you
Interesting no talk of perineal issues, which I feel like I noticed when my seat was too far back. Instead of sitting back and extending my reach I would just sit on the nose of the saddle and cause too much pressure there. I wonder what Neil would advise then for setting bar distance. I've always leaned towards bringing my saddle further forward and my bars closer, but I'm still having issues I'm trying to sort out so.... For me bike discomfort and therefore bike fit is probably the main thing that saps my enjoyment from cycling.
Could be a problem with saddle tilt, and not so much setback. Just my 2 cents. Everyone's dangly bits are different. :)
It would be neat too see this in slow motion,,, yes,,, finding that sweet spot makes a world of difference... Thanks for sharing...
Question : if you were to be able to measure the weight distribution between rear and front wheel, wouldn’t that be a way to establish the best position on the bike? Dunno, just asking...
I am new bike and I need a lot to learn from you, greeting from pacific.🚲🚲🚲 thank you Neil and Sam.
Thanks again for these fitment videos, really helped in understanding what my legs were trying to tell me. I'm re building a base fitness (casual rider) and passed most aches of as, you just unfit suck it up. Great guide and conversation.
A racer or casual rider should feel comfortable in the saddle. "Comfortable " is relative to the final position desired. Either way; you should feel good/comfortable on your bike. I hope you find that happy position 🙂. You will know it when you get it. You feel as if you are floating on your bike.
Great video mate. Neil explains it with very solid examples, which helped me to visualize the impacts of changes.
He is right about as far forward before too much hand pain. It really is an experiment, you will also have more power with the seat further ahead and cleats all the way back.
The last part of him talking about the saddle angle in relation to BB changing dynamically as the road undulates, are we presupposing the rider will be riding on level ground more therefore setback is established on level ground? If you’re a rider who spends their rides ascending 100ft/mile would it better to set the saddle for that?
I certainly ride with my saddle set up for at least a slight angle forward and less setback because i end up spending so much time riding uphill and got used to it in all situations
The Vertex Fit Cycle is the only fit platform that completely isolates saddle setback (effective seat angle) from the rest of the bike fit web. You can sweep it through a huge range of setback while rider works under load yet without altering distance to pedals, bars, drop, etc. You should check it out.
I have saddlebags for bikepacking on. That makes weight distribution always heavier on rear.
Amazing stuff but one thing i wish he'd have adressed is how i tend to compensate saddle for/aft changing by sitting differently on my saddle which makes it even tougher to address properly.
Cheers mate, Neill does sort of cover this at the end when discussing climbing but I know we could have gone deeper.
7:40 "Do the balance test when you're riding 20 minutes effort" ⇒ I understand it in the way that you *don't have* to ride this test for 20 minutes, it's just push your pedals for a few minutes but with Watts similar to your FTP. Am I right? Regards!
There's more to saddle set back than discussed here.
Spinal flexibility and low back pathology
Hip joint morphology (FAI)
Leg length discrepancy
Iliac artery morphology and effect of increased hip jt angle. (risk of iliac artery endofibrosus or compromised venous return)
Respiratory efficiency - chest expansion, diaphragmatic excursion.
Abdominal congestion/comfort
Injuries carried
Aerodynamics improvement by lower back angle and elongated upper limbs
Rider center of gravity and its influence on steering and braking control (especially relative to avoiding speed wobble)
Cadence efficiency and comfort
Endurance vs sprint power
Optimal saddle height and setback, and stem height/length are reached after consideration of which of the above are being prioritized.
In grand tours some riders adjust saddle position based on terrain and role within the team.
I was surprised to hear Neill confounding saddle setback with stem position.
Saddle height and setback are better determined prior to and independent of stem location.
Neill's views expressed here don't account for why most GC riders use a bike frame one size below recommended by the manufacturer.
Thanks for sharing
Working with my girlfriend on this recently. I know this sounds very novice but teaching people how to sit on the saddle first is critical. Too many new riders do not understand where the contact point is supposed to be and there is serious discomfort or injury caused by it.
Where is the contact point supposed to be? I tend to slowly slide forward to the nose of saddle as I pedal, then push my butt back to get the sitbones on the wider part of the saddle again. This keeps repeating. Not sure if it's about saddle fore/aft or saddle tilt, or other
Thanks for the great video. In listening to what Neill has to say re determining position when under load (close to FTP), what about a scenario like very long distance rides (300k+) where you are not putting out anything near FTP on average. Should setback be different as you aren't putting out the same forces to offload your hands?? Specific example here is a 200 mile gravel ride. Thanks!!
Great questions Alex, I'll set that one up for the new RCA channel where Neill will now be more involved.
@@CamNicholls Excellent...already subscribed to the new channel!
Thank you and Neil for this bike fitting series
Learned so much
I adjusted my saddle position forward until it felt right. Consequently I measured my 45 year old road bike which is like an old shoe. My new Cannondale Topstone L size wound up with identical saddle nose to center of the hoods dimension. The classic with 40mm shallow drop bars, the Topstone with wide gravel drop bars. The nose to center of bb dimension is also identical. The saddle height is identical. The Topstone has a more relaxed seat tube angle, and would be about a 57cm bike, The Dave Moulton is a very steep angled bike with a short top tube, and would be about a 53cm by most measurement standards. The only measurement consciously selected was the saddle height. Short leg length, long torso and arms. The sloping top tube allowed the L frame to have straddle height. It's amazing bikes from vastly different eras can fit comfortably, and ride so differently. Also my aluminum track bike feels great in a different way, but with vastly different handling ( razor sharp), and similar to that on the body after 100km!😂
Greetings from UK, I hope you're doing well over there with all this Covid_19 BS right now. Another brilliant video, by far the best on this topic I've come across. Thanks to Neil as well obviously. Safe riding 👍
Cheers Gavin, agreed re the BS
@Wooly Chewbakker You're reading it incorrectly. I don't believe the disease is BS, but I believe the media carry on and the way Govts are reacting to it is BS. People die every year of all sorts of illnesses including bad flu seasons that kill hundreds of thousands. However, COVID-19 is used as fear-mongering clickbait by the media and used to political advantage by Govts, rather than really carrying about the community as a whole.
I'm 6'4 on a 60cm cyclocross bike that I use for gravel and road biking... they have slightly different geometry from a strict road bike...
I find myself never being able to find a true/perfect position.
I'd say my limb lengths, torso lengths are all proportionate (in other words, I'm not 6'4 with long arms/legs short torso, or short legs long torso... I'm proportionate).
In order to get full leg extension... I extend my seat post fully at its limit. Maybe 1cm passed it actually.
Not only that, but I have to slide my saddle all the way back for a bit more leg extension, and reach (Since if I keep the saddle neutral or forward, I feel cramped up front).
I even have a 110mm long stem.
The position this puts me in.. gives me a feeling of kicking forward while my femur bones are too close to my torso (which doesn't allow me to put out as much power... although it puts me in a more aero position).
Issue is...
If I shorten the stem... I'm cramped.
If I slide seat foward... I'm cramped.
If I slide seat post down... legs don't get extension.
I think I've come to the conclusion that my frame just isn't enough for me... Gotta go full road bike, maybe a 61cm.
Thoughts from anyone? Looking for all the ideas I can get...
Thanks for another great bike fitting video. As Neill put, one thing changed can affect others. So what is the correct sequence to adjust the whole bike setting? Saddle height -> fore-aft -> cleat -> bar?
Good question mate, I’ll see if Neill can get to this
Hey...I'm not going to sweat the details. Right or wrong I'm comfortable with my current position.
If I bought a new frame then I may revisit my saddle position.
Hi good stuff. What would you recommend for a forward crank cruiser type bike where you sit straight up? I ride hard and about 40-50 miles a day.
Currently has the big padded seat which is terrible. Is my bike bad with the forward set cranks besides being inefficient and seat being far back? Thanks
Hey, thanks for these videos, it's a great source of knowledge ! One question, I found myself want to sit far back on the saddle in order to get the full muscles working correctly and to get that feel of pedaling in circles. How should I set my saddle to stop that need to slide back ? If I move it forward, I'll only exagerate the issue where I feel the need to slide back. I dont know wether I should move it back, up or set the cleats further forward to the front of the shoes. If you have any tips on this, thank you.
cleats all the way back and heels at 5 o'clock pedal position without any shoes on. I'm a nobody but you can try this for comfortable ride🤷♂️ it works in My case
I've heard of another bike fit quick tip on saddle fore and aft. Pedal at a cadence below threshold (ex95-105 is my face pace, pedal at around 80ish). Let go of the bars and pull your upper body up, too much core involvement, or a significant increase in cadence indicates your saddle position is incorrect. Usually an indicator of too far forward.
This is also assuming you've got all the other variables correct.
Interesting to hear, thanks for sharing on the thread Jaspreet.
I’m 6’ 4” tall and manufacturers have always recommended 60cm frame size for me. I have two bikes at this size but have generally felt a bit too stretched out even with a shorter stem. A year ago I decided to buck the advice of the manufacturer and bought a 58cm Cannondale Synapse which feels a lot better for me.
Even so, having followed Neil’s earlier advice regarding the balance test I still find my saddle needs to be as far back as the seat post will allow to pass the balance test and not slide forwards on the saddle. This is with a 15mm setback seat post as well and something that is also not touched upon in these videos i.e. seat post setback.
I’ve shortened my stem down to 100mm as well and it’s not slammed either but my position on the bike does feel a lot better. I’ve ordered 165mm cranks as well because I do have some hip impingement due to a couple of accidents in the past. That will obviously put the saddle up a bit as well.
Bottom line is even with the smaller bike, saddle right back and shorter stem I still feel like I am not totally nailing the balance test without sliding forwards on the saddle a bit when pedalling. I’m not sure where I can go from here. On my 60cm bikes (Scott CR1 so not race bikes) it basically is what it is. I’ve gone as far as I can with those and just have to accept that maybe they are too big for me.
I am 6’3”, 170lbs. I always have a very hard time doing the balance test. I’m going to go ahead and call BS on the balance test. I don’t think it works for all body types, especially tall guys like us.
I am 190cm and I also ride with the saddle nearly all the way back. I tried to move it forward but it didn't feel good, so I pushed it back again. So maybe there is nothing wrong with it :)
Get a 20 mm. setback seatpost. Maybe a 25 mm.serback is better for you.
