- So one of the most common questions I get asked is regarding 1x. So after a few failed attempts, I tried to make a video explaining my own reasons for going 1x, and also a non-subjective explanation with hard numbers that might help anyone decide if 1x will work for you or not.

1:51 The two big issues
4:07 Why I did it
8:44 Numbers (To help you decide)
I just went 1x - bike is intended to do gravel as well as road via a wheel swap - very happy. Road wise it keeps up with the guys on 2 x 11 and they are now looking at 1x solutions! I don't think the gaps between gears are a big problem - I am not that fussy/particular with cadence and this is offset by no need to deal with the front rings, front mech etc, lack of chain drop (gravel). I sacrificed a tiny bit of top speed on downhills, but not a problem and compensated by less complicated gearing setup. I used a XD freehub and which allows a bunch of other cassettes and gear options, I am running 10-44 which gives a wider range and my front chain-ring is chosen for climbing and the 10T gives sufficient top speed. Anyway at the end of day plenty of options re gearing and it doesn't matter if you are 1x 2x or 3x so long as you are riding and smiling
Cassette 10/40 fors shimano?
@@NinoSpinner Sorry Shimano Freehub will not accommodate 10T - have to install an XD Freehub, which is typically available for most modern hubs. 10-42 XD cassette 11 speed - available in SRAM (MTB) and I think for weight weenies the top line spec is 265grams. Shimano rear derailleur and shifting works fine. Perhaps, obviously, adjustment of B screw and appropriate cage length of RD needs to be considered. It is all do-able
You may want to pin this... It's starting to work its way down the comment section.
I went 1x last year.
It’s flat here, so the lowest gear is not a concern.
I spin out at ca. 58 km. which I hardly ever reach, because I don’t race not group ride and... yes... it’s flat here.
It does what I want it to do.
44/11-28
I’m considering 44/11-25. For weight and aesthetics.
So... not a hardcore traditionalist.
It works.
Excellent video 👍👍
Your explanation made me realize that I actually don’t care at all whether I ride 1x, 2x, or fixed - as long as I’m outside and the bike is under me then all is well
🤗😜
So thanks!!
That’s pretty much the best thing anyone can take from this video haha 😅
I need to go out as well!
From a guy who works 90% with people who speak other languages, your english is pretty good lol
Same opinion!
No apology needed.
Probably the best reason I can think of switching to 1x is not having a front derailleur.
2-6 Watts less efficient, chain needs to be replaced more often, some groups are HEAVIER than 2 x...
I don't see any reason to switch to 1 x, I suppose it must be something for MTB.
@@DR_1_1 for sure i have an old klunker with a 3*8. Tour set up. The chain is loose on granny but i need it to get my heavy ass uphill.
You wouldnt need as many gears if your just on trails.
I had the same 2x setup with 50/34 chainrings and a 11-32 cassette. Switched to 1x with a 38t wolf tooth chain ring and kept the 11-32 cassette. I hardly ever use the 11t cog. On steeper downhills I just coast, saving my energy instead of fighting the wind resistance .
That level of organization in your videos is superb👌
I tried one by four years ago, and I loved everything about it, simplicity, clean look,i was able to use all the gears, and few months ago tried double crankset again and for some reason could never find the right gear,so I went back to one by. I use mostly 44 NW chainring and 11-36 cassette
Also a one by 11 crit bike for the flats is amazing, 52 up front with an 11-28 cassette
Sounds like an ideal crit machine 👍
I’m still riding 3x6 uniglide on my old Ritchey. Does what I need it to do, which is make me grin ear to ear! 🤗
Richard Cannon the grin-factor will rule all other argument for sure! Happy days!
Rides of Japan agree 100! Buuut currently debating to build up a 1x gravel due to your videos. I haven’t bikepacked in 2 years. I got the itch for a project and an adventure!
RollinRat thanks. I’ve done a lot of touring on 3x and 2x in my days and I agree about range in mountainous regions. I just know for weekend trips that I want to do 1x will be sufficient.
I tried 1x for 2 years to give it a chance. Never could ride without gear hunting, and spinning out. I tried it a year and a half too long. Where I ride with tons of hills and headwinds. You're totally right in the beginning, if you're concerned about the gaps and your cadence, you're not gonna dig 1x and compromises you can't get around without 2x. And now, GRX gearing with 48/31 and 11-30/32 or 34 ,... game over , reverse slam dunk for the win for all-road/gravel riding.
Great video explaining the details and your reasoning for a 1x setup. We are pretty flat around here, and one of my bikes even sports a 1x9 setup with an 11-36 cassette and 48t chainring.
Strong man setup 👍👍
I had my 1x gravel bike on the roof rack of my car yesterday and someone drove up next to me and yelled “HOW DO YOU LIKE 1x!??!”. I rubbed my chin thoughtfully and said “Still getting used to the huge gaps”
very helpful video and explanation! thanks a lot! i'm going to switch from 2x to 1x and now my knowledge is much more complete. great job!
Flawless video! I think with a 1x system you have to just accept that your speed or cadence may not be optimized in some situations. I put a Wolf Tooth Components 34T front chain ring on my old, 26" mountain bike, removed the front derailleur and shifter, and installed an 11-34 nine-speed cassette on the rear. I am using this bike as a commuter, with a rack and rear pannier bags. The gears are low enough to climb up the hills in the Metro Denver area, and still give me a top speed of 23.14 mph at 100 cadence. I certainly can't keep this bike at 20+ mph on the flats, so more gears just doesn't matter!
Well done. I have a Haanjo Exp with a 2x, 48/32 crank and Deore M-6000 11-42 cog. I'm in WA state and can't imagine just a 1:1 ratio. Some gravel out here requires an MTB trail approach and some of the roads around I-90 are quite steep.
Sounds you have all bases covered!
And sounds like you have some fun terrain as well 👌
I ride 1x7, works perfectly. You don't need that much gearing. I am not riding tour the france every weekend.
I run a 44 x11-36 (11 speed). 44x11 is plenty for speed, 44x36 is about the same as 34x28 so fine for climbing as well. The bottom is 11-12-13-15, I do notice I miss the 14 on the flats. Will probably change to 12-36, still plenty of speed possible with 44x12.
I seriously recommend ritzelrechner.de/ gear calculator for visualising and deciding on gears if you hate tables full of numbers. Great tool to compare your setup with your possible next one.
If you are not trying to win races, 1X is very viable, is simpler and lighter. Ezpz.
I enjoy my cycling but i'm no tryhard, 1X is all good for me. The "bigger gaps" crap never bothered me.
If you are trying to beat KOMs in your area, trying to win competitions, or are overly sensitive to ratio gaps or whatever, then go 2X.
Very informative. 👍🏻 Hope you’re feeling better soon. 😷
if only id seen this before I bought. keep putting out the great content
Your english is great and much better than my Swedish or Japanese!!!. Dont be that hard on yourself!!!
That video was great. Congratulation from Spain
I am 61 , I dont ride fast once above 20mph I'm rolling. I have just converted my bike to 1 X . I'm using 28 chainring and 11-42. It suits me and I like the simplicity. The big jumps arent a problem as they are in the low gears , by the time I am using those I just spin and chill and sometimes almost die :-)
"a very strong typhoon in my back" 😂😂😂😂
Thank you for this info.
I live where the hills have hills and I do mostly transport and touring, have a child who has decided that due to hills, seeing cars hit bicyclists, while also having a heavy Norco kids' bike, has deemed that she hates riding her bike, and this info hopefully helps me inform how I can make her love bikes again as we upgrade her bike and maybe mine.
Not interesting? This was VERY interesting & helpful, gratitude for sharing your thoughts & reasoning behind your decision to go 1x.
I'm eyeing a Chinese clone of the Open U.P., as well as a well used U.P. first version (post mount), O'm still undecided if you or others would like to give some input....?
Joseph Farrugia I can’t comment really on the Chinese clones as I don’t have any experience with them ... I hear they have gotten a lot better lately though.
I still prefer the originals obviously, but better a clone than no bike at all.
I changed from x1 38 - 11-40 to the new grx 48/31 and 34-11 for better speed on the flat
Love this topic, which is really two: what are the pros and cons of 1x and how to choose your gear ratio. We have been working on a automated calculator for finding the best gear ratio which will give you a recommended setup from a few basic variables....but I have been distracted. You have just encouraged me to dust it off again. Cheers from UK
Nice, looking forward to see what you come up with 👍
Nice! Did you finish the calculator yet?
Great video! Clear and camera/editing is superb.
よろしくお願いします。
Well done. Thanks for putting all the work into this!
Haven’t watched the video yet, but hope you addressed that SRAM AXS 1x has Less range than non-AXS. You get the 12th gear, but lose range. The only solution other than 2x is to mullet with the mountain bike Eagle AXS rear cassette.
You speak english better than I do and I live in the States! It's a very complex and difficult language to learn.
Great vid.. after taking my 1X 40/42-11 Sram Rival on a few recent groups rides w roadies, I can definitely notice the gaps in my cassette. May have to create a Franken-cassette myself for better spacing (spin/cadence) on the 11-18 ish cogs (taller gears) so I can ride at a faster pace without too tall a gear to pull. Your analysis on speed changes when going up and down the cog as interesting, where cadence was constant.
Great video as usual! You should do a Q&A, love watching your witty talking videoes ;)
Even with overlapping gears on 2x, being equal in ratio does not mean equal in friction drag as smaller cogs and rings of the same ratio will be less efficient. This means that even if you have a tall enough top gear in 1x for a reasonable top speed, the drivetrain friction will be greater than on a 2x. Is it enough friction to matter? Depends on what's important to you I guess. Having ridden and raced during the last 25 years, I want the best riding and pedaling experience possible. Getting rid of the front mech and going 1x does not improve my experience, it makes it worse due to being less versatile. Comparing a total range between the gear ratios is not the same as having two sets of ratios in the real world.
The weight savings is negligible and shifts more weight to his flywheel on your back wheel which I can feel. One of my bikes has a 3x7, totally old school and I completely enjoy the utility of even 3x over the progressing drivetrain technologies over the last 25 years.
Does 1x allow you to have more fun or faster, or is it just about fulfilling the insecurities brought about by bicycle marketing managers? Plus if you change your environment, you'll have to change your chainring to be optimized for that environment, where with a 2x, you should be preparted for riding in a wider range of places without changing anything.
This.
1x definitely improved my experience. I build my Gravelbike with a 2x system and immediately hated the front mech. I hated the shifting complexity, the Noise (Di2 front mechs are very obnoxious) and that a huge part of the top range was u usable for me. Even with my 1x I never use the smallest cog, I only use as big a chainring as I do (42) because it gives me a straight chain line during a normal effort on flat roads. Yeah sure the friction in each gear on 2x might be a bit lower, but that is not worth all the hassle that it causes.
Btw, by your logic, you would also need to change your rings in a 2x if youre switching environments, because you'll not be perfectly efficient anymore if your average speed and therefore gear changes.
Thank you for using font colors that match your cap
Willis Thompson thank you for noticing 🤝
Your English is not sketchy man it’s great
Good film! Yes, the rainy season has been long this year. I'm wondering whether using a 1x system would be preferable on my commute bike. 22 gears seems just a waste. Yes, on the flats tailing behind a dump truck I put some good speeds out but generally not much above 45kms (good day) by myself. Great info and I will ponder further!!!
バイクパッキングの動画が面白かったし、キレイでした＼(^o^)／
I like your bikepacking video. I could learn how I pack the stuff in bikebaggs and what I need to prepare for it. I also like the drone filming while you biking in the mountain. The view from drone is awesome!! Sky, mountain, and all the nature was so beautiful! So I'm planning to go bike and camping soon. It seems like rainy season is gone lately in Japan!!
Kiyoyuki Imai 今年の梅雨は長いですね。これから新しいバイクパッキングの動画作っていこうと思ってます。🏕
This is a great video, really helped be select the drivetrain on my new bike. I think I'll be going for a 1x11 with a 40 tooth chainring and a 11-42 cassette.
Seeing as I ride mostly fixed, I'd probably be overwhelmed on a bike with 22 gears. I am on the market for a geared bike and I am pretty much set on getting something 1x. Also, the area I am living in is flat as a pancake. I simply would not know what to do with a massive gear range found on 2x bikes.
I'm lucky enough to have multiple bikes and have both 1X and 2X setups. I know it's just shifting gears on a chainring up front, but honestly, the 1X setup is far simpler, there's less fiddling around, and I really not bothered by the larger jumps between gears. I know opinions vary, but given what you describe, I think you'll like a 1X setup.
Great video!
It would work for me. I would choose a 44t chainring with a 11-32 cassette. That is still 46 kph at 90rpm and the easiest gear is even a bit easier than what I have now on 2-by.
That's what I chose for my Aethos build, figuring the light weight would a factor at 12.9lbs with pedals! I'm just testing it out this week.
I remember I bought 2by system from Canyon because I thought 1by is slower, but 1by SRAM had 10-42 cassette + 42 ring vs 2by Shimano which had 11-42 + 30/46 ring, I think that fast gear on 1by system was smaller, therefore is actually as fast as 2by system. I wish I knew that calculator so I could check before I bought it. I really liked 1by AL Grail AL 7.0 SL and it was in stock...
Really great video. Thank you!
Just RIDE. Ride what you have, ride what you can afford. Just RIDE
No arguments from me 👍
So...I have four bikes. Two of them are 2X and two of them are 1X. If you MADE me decide, I think I'd pick 1X, primarily for the simplicity. I can't say that I miss the closer intervals of 2X and I certainly don't miss having to shift chainrings.
I tried many combinations on paper for a 1x setup for my Venge but none were functional since I ride a lot of very fast downhill where I can easily reach over 70 kph and I also do a lot of climbs. So the 11-40 cassette has too big gaps and I can't figure a chainring size that would fit my top and low speed. Furthermore, a good Di2 setup will make you forgive about the front chainring shifting.
Anthony HT sounds like 2x is a no brainer for you then 👍
@@ridesofjapan sadly it will be a 2x. I wish I could have a 1x like my 2013 MTB but the gear ratios for road bikes aren't not easy to deal with.
Anthony HT don’t be sad 😜
It’s all about maximizing the enjoyment in the end! 👍
Your English is great. How many languages can you speak?
Speak two... making myself understood, three maybe ;)
I also live in Japan, ride 1x FSA Omega 42t crank and GRX clutched rear mech. I definitely won’t go back to 2x! 1x narrow-wide chainring gives that instant moment transfer to the wheels, like on fixed/track setup. My cassette is 11-36 XT, and I feel quite comfortable on japanese mountain terrain.
Great video my friend!
Brilliant. I run a 11-46t rotor cassette with smaller jumps on the the bigger gears and decent climbing gears paired with 44 ring in the front and sram AXS red derailleur
Wanted the same 11-40 cassette and XT mech; however, wanted a very low climbing gear, and a reasonable road gear.
So, picked the 28/38 (cough) double chainset.
I have both shifters as a gravel bike, so no problem there.
another great video. Your content is always great no matter if it's talking or not talking, or talking with a frog in your throat (get better soon!). I do this sort of thing in Excel but I may give the site a check, thanks. The thing that occurred to me is that someone needs to make a continually variable transmission for bikes! No more cadence jumps, just pedal faster or slower. Well, it's a dream, maybe...
Think about the cassette as a pyramid. Going higher to a cog with less teeth. Going down to go slower and easier
Or think of it in normal automotive terms, 1st gear is slowest gear with most torque (easiest).
42CR with an XD river and 10-50 12 speed cassette will give you everything you need, but the problem then becomes brifters not supporting 12 speeds. But wait, AXS to the rescue ... once they start selling individual components and you can mix the Eagle AXS 10-50 capable rear derailleur with the Force or Eagle 1x shifters. Currently you have to get 2 AXS systems to mix/match, spend a fortune and try like hell to recover some costs by sell those components that you didn't use.
neutered10mm yeah, I don’t really need the 50 cassette, but paired with a rotor 11-39 cassette I would be very happy.
Not really looking to go sram though... but if Shimano keeps stalling there might not be any other choice soon 😅hehe.
I think its ok/good for mtb but road and gravel seems to miss the spot for me.
No. I'm surrounded by steep hills. I like to be able to select easy mode on the way up, and I like to go as fast as possible going down. So 34/50 and 11/30 is perfect for me.
I realy liked the site ritzelrechner.de for finding the gears I needed for one by on my bike
White page on Chrome.
I have combined my GRX 1x with an 11-46 XT cassette in the back. I used the Wolftooth goat Link to manage „smooth“ shifting. I like it a lot on my Gravelbike.
A good explanation. I tried 1x with a 42 with an 11-42 cassette but I did notice the gaps. Where I live there is a lot of flat road between gravel sections and those flat sections always showed up the missing cog for a comfortable travelling cadence. I now have the Praxis Alba 48/32 with Shimano RX long cage derailleur and 11-34 cassette. I love it for both gravel and road rides (two wheelsets) and if I run out of higher gears on downhills then it’s the gear god’s way of telling me to coast.
Andrew Kirk coasting is underrated 😁✌️
just my two cents, 1x hype is just marketing from the industry, yes there are few new tech (xd driver, 10t smallest cog etc) but I’m using my old miyata 1x7 !! for commuting here in kyoto (that bike is 30ish year old-was top level hybrid mountain city bike back then) so if you still confuse whether to upgrade or change to 1x, just try it !! I personally still using 3x10 for my mtb and 3x9 for my touring/bikepacking/gravel steel bike and Do Not Need nor Want to change to 1x ... why? money ... hahahah tried several low end 1x bikes and I don’t feel any real advantage for my style of riding.
I went from a 1x12 to a 2x10 set up on my gravel bike. 30-42 in the front and 11-336 on the back currently. I have not had any issues so far with it (3 months). My speed in flat is excellent, and when I get extreme climbs I have the gearing, unlike before where I had to give up on speed or climbing. So it's up to what you decide to ride on!
Diego Aguilar 11-336 is a pretty good spread! Sounds like some big gaps though
Diego Aguilar excellent, as long as it makes you enjoy the time on the bike more, you definitely made the right choice for you 👌
Thanks, and yes, there are some gaps for sure, but so far they are manageable!
@@diegoaguilar8789 Agree 11-36 10 speed is a nice compromise on range and gaps. Have it on my 29er. Have 11-28 11 speed on the old CX and often change 2 gears at once because gaps too small.
Have 1X for one and half years , finally back to 2X. Not issues of gaps or edge ratio, but the f**king Sram Force narrow wide chainring and stupid chainline. When I use 1X 42T front 420mm chainstay on flat road in 30kph, noisey chain and 180w power to maintain it. Swich to normal Red 50T big ring, quite & smooth just 165w power demand.
I'm also thinking of going back to 2x because of noise. Currently running 3T cassette.... Maybe they are just noisy.
@@byrondixon4648 in my case. the main noise comes from the chainring especially using small gear. The hg800 11-34t cassette is ok.
8:25"The only time I really go hard is when I'm climbing". 🤣🤣
I need help choosing tyres for a 100km off-road/gravel race. It’s birkebeinrittet in norway. Do you know of it? Haven’t done it before but I hear it’s mostly pretty fast and not too rough but I think there a couple rough sections, although based on average speeds I’m guess these sections aren’t that long.
Should I go slick-ish challenge bianchi/panaracer gravel king and go for say 35-36mm or should I get something with a bit more bite to the tread and possible more like 33mm??
What people winning all the biggest gravel races on these days?
James Hooker I hear the top racers at Kanza rode pretty narrow like 35 (not slick)
Ted king I think was on 40s
I have no experience racing gravel so I’m not the person ask... I always go as big as I can 😬
Rides of Japan thanks for the input. Think I nust need to buy both panaracer GKs and GK SKs and test them both ;)
I am big and heavy 100kg rider. Using 46x30 at front and 11-34 with 8s in the rear end, my cadence is very slow and I just blow maintaing more than 70rpm in the heavy gear...
Great video! And your English is excellent, BTW.
Jason Jarvis youthank! 😜
I watch your videos mainly for the sarcasm 😆
Nick Mancello 😬
The biggest issue I have with my 1x (Sram) system is a sticky back clutch after riding on salty roads in winter
Been on 1x for 2 years now, love the simplicity of it. Sram Force1 Easton EC90SL cranks with 48 chain ring and 11-42 in the back on a steel bike. There are a few 18% climbs in my area and some 25% but the elevation gain is never more than 150m at a time so I still have the gearing with the 42 at the back and better speed with the 48 up front. it came with 44 chain ring but i was maxing out on group rides and needed more top speed.
How many speed bro? Is it possible on an 8speed 11-42
Yeah how fast could you go with normal cadence?
Super helpful for anyone considering ditching a ring or those already on 1x who're thinking about changing things up (me)
Peter Shaw happy to hear that, cheers!
Great information as always!
Yeah, for my road bike I am using 11-30 & a 50/34 works great...I am now living in Spain and I thought that the crazy hills here would assassinate me with that combo, but after a year of training with those chain rings and cassette I find it to be doable. My legs have pretty good watts potential. But heck, for a gravel bike I would SURELY try a 1- X
Watch for those earthquakes out there! Lately the whole land mass of the earth is rather active! :0
Good video, i have one inocent question, do u think is it possible to use a non expensive 1x12 MTB transmisión instead of 1x11 in order to have less gaps between gears? thanks!
Problem with MTB 1x12 is there’s not many cassettes smaller than 10-46.
Can only think of rotor, but that are very expensive
I'm feelin a Mr. Rogers groove, just being neighborly and trying to make the world a better place. Thanks for another great video with pertinent content. "Please, won't you be my neighbor"
You worry too much about your English but it actually helps me being more focused on what you say... Strange I know. Important question!!! What's the cycling cap you wear? Please? :)
_Black.Pearl_ haha, excellent!
Caps are from my mates at voidcycling.com
@@ridesofjapan perfect thanks!
how do you like the EC90SL cranks? ive had mine for 700km so about 5 weeks and they have shit the bed. the carbon cranks have started to dis-bond from the spindle and they creak and click like crazy... Very disappointing, currently undergoing a warranty claim.
Matthew Napier I’ve gotten similar comments from other people as well. Luckily they still perform flawlessly for me. (Their BB not so much)
I’m keeping an close eye on the bounding areas though.
From a SSer’s perspective.... IT’S OK TO GET YOUR ASS OFF THE SEAT!!! Once in a while.
I am awaiting my GRX 48/31 crankset (paired up with 11-34 11 speed cassette). Reviewing the numbers in the third part of your video did make me think I made the right choice to stick to 2x as I am particular about my cadence (I do have 1x on my MTB). Another not so obvious (and less important) reason I felt it was right to stick to 2x: I am running mechanical (Ultegra/GRX mix) and I don't have a dropper post. So my left hand shifter would be useless, that thought somehow did not sit right with me.
Mission accomplished then 😁👍
Cheers!
No worries about the top speed here ... I'm 74 and grabbing the brake lever on the downhills .... Di2 with 36t on the crank and 11t-36t Cassette ... loving it !!
my "road bike" is a CX bike with a 44t chainring and a 9-42 cassette on the back and 38c tires. I have nearly 1:1 low gear and a 4.88:1 tall gear.I ride mountain bikes so the gaps are actually smaller than Im use to. How well does it work for me? Perfectly, I can climb anything and not spin out on descents. A double chainset would have to be a 53/34 with an 11-34 in the back.
Your English is pretty much perfect. Reminds me of time I spent in Sweden though.
Gaps bother me on rare occasions when I am forced to climb.
Stuart Dryer 🇸🇪✌️
You should try 1x12, you can use any of the SRAM Eagle shifters (although you won't be able to use drop bars unless you go AXS) and depending on the cassette, either one of the Eagle derailleurs or SRAM mountain bike 11 speed derailleurs. You could use the 11-50 cassette to be able to run a larger chainring with the same gaps as 11-42 , or even 11-52 from Aliexpress or Rotor, the latter also offering 12 speed cassettes of 11-46, 11-39, and 11-36. Rotor's cassettes seem to favor smaller gaps in the harder gears which you'd prolly prefer. Or just go full Rotor 1x13 with the same cassette ratios plus a 10t cog if you're willing to go hydraulic shifting.
Braŭljo the rotor 10-39 looks like the first cassette that actually got it 100% right.
Didn’t quite understand if they will make an 12speed 11-39 version as well, it they did it would be perfect for my future di2 12 speed 🤞
@@ridesofjapan Yeah the 10-39 is their 13 speed cassette, whereas the 11-39 is their 12 speed cassette which are both already available. Does Di2 support 12 gears tho?
Braŭljo not yet unfortunately... was ready to jump on the new xtr di2 12speed but it never came, which have me thinking they might have something new coming for their electronic 12 speed, time will tell I guess.
The bikecalc website was invaluable when setting up my 2x and 1x for gravel. My 1x is 42 × 10-42 (Rival)and my 2x is 46/33 × 11-32 or 11-34(Ultegra). I can ride both and adapt to the cadence changes easily with my only problem being switching from the Shimano to the Sram shifting action...but after a few miles it's second nature again.
Love your videos...Keep up the great production and content.
Agree! It fun just to play around on that site for my pretend dream 1x14 setup 😁
Cheers mate!
Coming from a MTB background so once I got my first road bike I got rid of the horrible front derailleur cables and everything and I smashed an 11-46 at the back, now it feels like mtb with skinny tires
Hate 2x so much. Hate how just before a climb as you’re shifting to easier gears, eventually the chain rubs, prompting you to shift to the little ring, and then you have to compensate by shifting 2-3 harder gears in the back. So stupid, annoying and counterintuitive. Hate the force on the left hand required to get from small to big ring of mechanical groupsets and the gamble of the chain falling off while shifting small to big on bumpy roads. So stupid. And I’d much rather stand up while climbing the steepest parts than have a super low gear and deal with all that BS. And for me the 11-13 jump is fine because 11 is a bombing downhill gear, not useful on the flats while seated. Its also a good standing while pedaling gear on the flats to bring back some circulation to the ass. Even the 13 isn’t used that much on flats. 15-17-19-21 is the cruising gear range and those gaps are actually pretty small, and they’re pretty close to the middle of the cassette for a good chainline and quiet chain. Love 1x and not going back to 2x unless to add on a super granny gear like a 24 to my 42 for loaded touring and just super steep mountain roads that go up into foggy wild heaven.
Fantastic video. I live in very flat area and I am looking to convert a bike to SRAM AXS eTap, but something in the back of my head said go 1X, since I do not have to worry about hills. We only have bridges and wind, and there are days where I use the small ring to battle the wind when it kicks up, but since I run mechanical and a 12-25 cassette with a 50/34 , I have a lot of single tooth shifts to find the best gearing to fight the wind. I never knew about the BikeCalc, that will help me in my decision. Kudo's sir.
I was a mountain biker first - back in the mid 80s.
I didn't start riding road until I started racing XC seriously in the late 90s. For training.
I think because I still have that mountainbiker mentality - the gaps in 1x? Yeah.. they aren't an issue.
Cadence is usually not the focus on an MTB - simply getting meaningful power down on variable terrain is.
So you dont fret about getting that "perfect spin" because on an MTB... alot of the time when you DO find it, you have to change it up to accomodate terrain.
I have a tendency to do the same on the road bike. Instead of gearing down to Crest a small rise, I just add power - and my cadence goes down, power goes up, but speed stays the same.
I just got a new Checkpoint ALR 4, 2021. It’s a 2x10, GRX 400. I really wanted a 1x, but this was available and affordable in a scarce market. I also really liked the fit and ride of it. What parts would I need to upgrade to a 1x system for it?
I live in a hilly town. I found the high end gears to be a waste. I found that a 34T chainring /11-34T cassette worked. Interestingly, I am converting to a 32T chain ring as it affords me a smaller cassette of 11-32Twhile still giving identical ratios. I also think a friction thumb shifter keeps you far more in touch with your bike mechanics while eliminating the finicky adjustments of indexed shifting.
Odd isn't it? I shouldn't be interested in this yet I am! Another brilliant vid. Thank you. I'm an old, heavy (or fat 🙄) x2 roadie with rim brakes and NOT tubeless, so WTF but this, like all (ok, most) of your stuff, was really useful. 🙏
Graham Wynde cheers mate! that’s probably the best type of review I can receive ☺️
11-42 cassette gives exactly the same range as 50/34 x 11-28. So only the gaps would be the issue IMO, especially with 11-44 or 46 cassettes available. Wish I could completely make my own cassette though.
Jaap for me a the rotor 11-39 (or 10-39) cassette has got it pretty much spot on... only need Shimano to catch up with the 12speed di2.
Hell no, the gaps are too big and I really want my cadence to stay above 90. For my MTB I use 1x but the changes in effort are typically a lot bigger, and sustained effort with minor changes in cadence does not really apply. I run 46/30 + 11-30 on the road, and 11-34 for gravel. My cadence is pretty high - average of 100+ otherwise I would run like 53/36 or some such likely with the same cassettes.
1x11 for me! 42 front, 11-42 rear and if I start to nitpick about a "gap" I just shift higher and tell myself to not be a pussy and get stronger.
I've got a 50/34 11/34 set up, and often find myself switching between chain rings to find the right cadence. I need the 11 gearing on our hills, my bike is 10kg, and I need that extra gear (last bike was lighter, and only needed 28 biggest cog. I can do the maths, but here's a question that might not reveal itself on numbers alone: when I get out of the saddle (without a change of gradient) I click down a couple of rings. With the bigger cog gaps, do you find yourself still clicking down 2 or 1, or is that not noticeably an issue?
playandteach when I was on 11-28 is was shifting between 2-3 gears when going from sitting and standing, now on the 1x I shift 1-2 gears.
I ride a Giant TCX 1x 46t chainring and 10-42 cassette. Working great on both gravel and road, plus occasionally a bit of singletrack. I love the simplicity and the gaps don't bother me.
Thank you @ridesofjapan for making this video!
Great video!!! As someone whose just an enthusiast/amateur rider and not pro or former pro, you can get caught up in all the hype. I wasn’t sure whether to go 2x or 1x for my new bike. And then I thought about it a bit differently not long ago: I live in the flat flat flat Midwest USA and we don’t have climbs or anything. And for riding in a fun event where there are climbs, I can just swap the cassette. I got two wheel sets, one for gravel one for road. On the road I have a more compact setup since it’s so flat, and the gravel wheels run a wider range. Being that I’m an athletic rider at 100kg, and I’m not a pro bike mechanic, having less thing to go wrong and less parts to have to adjust is great. And last fall I finally switched my XC MTB to an Eagle 1x, and I realized how much I love not having the huge jump caused by the front gear change. It’s great. :) Maybe not for everyone, but I love it.
1x seem's better suited to climbers? but climbers have to descend also! Choices, choices.
i'm currently riding a cross bike with a 40 front ring and an 11-36 cassette and i don't like it all, i don't have much speed on flats and spin out quickly on downhill and it isn't all that great for climbing either, not really sure what i should swap it out for
Korup7ion sounds like 2x would work much better for you then
Come ride w/ us in Korea bother.
