Good video. Just got a new bike and went back to coil. Have bottomed it out a couple of times. Tuned spring calculator suggests a 25-50lbs increase from what I’m running now which makes sense.
Bottom line: go see Mike or call Lost Co to get the correct spring. I bought a marzocchi Bomber CR with Fox SLS spring from these guys. Mike set it up and took all the worries and work out of it. So just to go to your local shop and get it right. Since riding my set up I spent a week or so tweaking with compression and rebound and now I only make slight adjustments for summer vs winter riding. So worth it. Thanks Lost Co guys
So I did everything backwards. Spent all night bashing my head into my laptop trying to figure this sh*t out, found your website and ordered a spring this morning. One of my buddies just sent me the link to this video. Boy I wish I had found this sooner, but hey, you still got my business! My spring shipped this morning. I’ll likely be a return customer in the very near future😂 But, all that being said, great video and thanks for dumbing it down for the noob here.
Yes I run coil shocks on the rear of my 03 Azonic Saber . And It came with the Romic .( which came on the used frame ).It has a 650lb × 2.43 spring and I am only 5'7"-160lbs. Without even trying to set the sag formula , im sure the spring isn't the correct rate for me know ,after watching your cool info show. So now Im going to hit the calculator and most likely buy a progressive shock that will suit my size . And I will take ANY advice you may throw my way . great video , great info, great channel. Stay cool brother.
Yeah did that and then called y'all and talked to Alex and decided to go one higher on the spring rate that was recommended for me, because on the type of riding I like to do mostly. Thanks
Hey Mike i was just wondering is it possible that you coud do a basic setup video on the dpx2. there is just so much going on and it would be helpful to get a baseline to start friom, your 36 grip 2 video is great btw
If you have an air spring installed, you can calculate the force needed based on the air pressure you set it up to. You need to measure the piston diameter tho, or get some technical drawings from the manufacturer.
Super helpful just like your other video on tuning the Grip2 fork. Thanks dude. Also, I really like your cable-less iMac and the artifical typing haha. "And the Oscar goes to...!"
(For those light riders) This is perfect for me i have the same bike but i weight 132 lb, currently im riding 450, and i feel like i have to put a lot of more effort than my old airshock, specially on jumps and lifting the bike. I should use a 350lbs spring
I only run air, will rarely swap bikes after recent purchase, could never justify buying extra springs "cause i gained few kg" or cause I carry a lot while in the mountains......so i clicked this video
Would love to run a progressive spring on my stumpjumper, but no one makes a 650 pound spring, ya ya ya I know I need to shed some pounds but it is what it is.
Hi I just enjoyed your video Amazingly explained Can you please tell me which Spring will be fit for my Motorbike for proper sage and jumping recoils My bike has a long dirt bike like monoshock but its spring is too soft not working properly My body weight is 62 kg My monoshock total length 15 Inches and spring length is 8 Inches with 9 Coil loops having 10mm coild external diameter but its too soft and when I sit its sags 1 feet to ground too soft
Spring for rider weight and valve for riding conditions. You should not use a stiffer spring to prevent bottoming out. what you need is more low speed compression if you are bottoming out on big hits, and more high speed compression if you are bottoming out on sharp edges. If you are near the end range of you shock adjustment and still bottoming the internal valving is not aggressive enough. using a spring that is too stiff will just result in poor traction and a bouncy ride.
Cool video, love the energy. Coming from a HardTail into a trail bike, I was wondering if the fittings (bushing/bearing/pivots) of the shock are a standard size. Cheers
I bough a Commencal Meta Power SX Race 2 weeks ago and it has a RockShox Super Deluxe Ultimate rear shock. It came with a 450lb spring on the XL frame size. The TF Tuned website suggests 495lb at 33% sag or 529 at 28% sag. I havent noticed the shock bottoming out but I suppose it has that bottom out bumper so it would probably soften the blow a bit. I'll probably buy one of the 500lb red RockShox springs at some point but it seems to be running fine for now. How much lighter are the red springs compared to the black ones? Or is it simply colour?
Hi, How do you choose the correct progressive spring weight?. I normally use 400 lb x 65mm linear spring on my 230x65mm coil shock 28-30% sag. For example some brands spring show MRP 400+ x65mm, others show DCO 350-400lb x 65, others CANE CREEK 400-488x65 and I get confused, I'm not sure if those are the correct weight o should I chose the next range with more weight. Thankyou.
Cool info. Just got a used 2016 DB recoil 29er that has a DNM burner rcp2. I can't read the spring rating because its worn off. I'm sure im heavier than the previous rider and the pedal bob is pretty noticeable. I dont have an owners Manuel for the bike or shock so I don't have much info about those numbers you mentioned. Im considering a new coil or a new shock upgrade possibly. Progressive coil sounds nice too. Mostly trailriding and stiffer might help me pedal longer with less fatigue but I am interested in stepping up my riding to include drops and jumps full send. I have a Manitou marvel 120mm on the front. I don't even know the travel of the bike on the rear lol. Any help?
I have a DVO Jade coil on my YT Tues now, size is 10.5x3.5 and I'm having a heck of a time finding a lightweight spring that is long enough to work on it. Pretty much looks like the standard Fox steel spring is the only one that fits. 😞
I'm 110kg with riding gear and I have a 2019 Stumpjumper Comp Carbon 29 wih 140mm (50mm shock stroke) of rear travel. Ive seen others running coil and I know that the Stumpy has a progressive leverage ratio so I'm considering getting a Fox DHX2 to match the 36 Factory Grip 2 I bought recently however when I check the spring calculator it tells me I need a 750lb/inch spring rate for my weight and leverage ratio. Unfortunately the Fox SLS Springs only come in rates up to 700Lb and I cant even find one of the regular black springs in a 750lb rate. I would really prefer the orange SLS spring because of the weight savings and also I just think it looks cool and would tie into some of the other orange bits I have on my bike. Any help?
How can I replace my 500lb/inch coil for a 750lb/inch coil for a 184x44 rear coil shock? I just want to change out the coil not the actual shock. Is there a way to purchase a 750lb/inch coil for a 184x44 rear suspension? I’m 300 lbs also….I appreciate the help man. Thanks!!
Shockcraft advanced is the best spring rate calculator. Why do you measure sag with full weight? When going down hill you will be in attack position on an incline. A 30% sag the way you do it will turn into a 20% sag on an actual ride. Add preload to stop bottom out is not right. Choose spring from mass and lr. Choose sag from kinematics and riding style. Use HSC damping adjustment to control bottom out.
Depends on how the brand measures it. With fox they say a 2.25 free stroke spring works with a shock stroke of 2.25 or less. I assume there's a bit of leeway in that measurement.
Get a EXT spring. Their tolerances are +/- 5% whereas a Fox spring for example is +/- 30%. Get your spring dyno tested to ensure a 420lb spring is actually 420lb
Do I have to purchase hardware when purchasing the rear coil shock to mount on my bike? Looking into purchasing the bomber cr because my fox x2 keeps squelching!!
Hey Danilo! You could use the mounting hardware from your Fox X2, but it also sounds like your X2 just needs a rebuild to make it sound brand new again! Popping the mounting hardware out of your old shock and into your new one is something you can do by hand, so you don't have to worry about buying a new tool for it. -Tor
What would happen if different lengths of spring than is designed for the shock is used? Given that they fit and other than length and proportional weight, are the same.
So its common for people who are more freeride and jump line focused to want a stiffer set up for bottom out protection ? I always kinda felt everything i rode should be a bit stiffer. would one of the main cons of this be a rougher trail riding ?
Every rider prefers a slightly different setup! However, the 28-32% sag range generally works excellent for all humans riding mountain bikes that aren't competing in Rampage. However, if you just prefer a more stiff and supportive feel, then that's just how you like it and how you should set up your suspension! -Mike
Quick question for anyone who can help. I need to change the spring my bike came with as I’m pretty light for my height. Current spring is 450x2.80. The manufacturer calculator says I need 350ibs spring. Does the 2.80 stay the same? Is that just the value I need for that particular sock? Thanks in advance
i currently have a 330x2.5 spring on my bike. this came as stock and ive always tried to use preload to stiffen up the spring. this video showed me the proper ways. only question is, after putting all my details in the spring calculator, it recommended 685-695 spring rate (yes I'm heavy). I went with 700 as this was the closest i could get, but the other number is different than 2.5 I had to go with 2.8. will this change, 2.5 to 2.8 be an issue?
You may need to get a different adapter for the larger diameter spring. Shoot us an email or give us a call and we'll help you more! sales@thelostco.com // (360) 306-8827
best thing is to order 3 cheap spring try each and find the right spring rate, then send back the other ones they usually show no use of wear after one ride
Hello, I just got a Santa Cruz Megatower with the Rockshox Super Delux Select with 160MM of travel. I would like to still the Red Color Spring, which spring will I need buy?
Did you enjoy finding your spring rate? Or did you think it was a pain in the butt?? 🤔
Too much fiddling and work for marginal gains, not my cup of tea so I'll stick to air.
Good video. Just got a new bike and went back to coil. Have bottomed it out a couple of times. Tuned spring calculator suggests a 25-50lbs increase from what I’m running now which makes sense.
Wait, what do I do with the bottom out bumper again?
TF Tuned was pretty much spot on with the spring rate that I had to get for the amount of SAG I wanted on my bike.
What's the wheel travel in the TF Tuned calculator ?
6:03 the computer is not plugged in but he's still using it

Thank you! This really helped getting a coil PROPERLY setup on my bike.
Great video. You answered every question I had about this subject. Now I'm confident that I am educated enough to buy the proper spring.
Wow! thanks for making this video. I found it more informative than GMBN and other Coil shock Videos also the calculator was a great help.
Just brought a frame that comes with a coil , this video is very helpful for a first up coil owner

Best vid i've seen on coil shocks. Period! Thanks man.
This was on a few days ago. And it back on again. Mike we seen you, to many times now. 😂
Haha we wanted to make an editing correction that we caught when we uploaded the video Sunday. Easier to do it now rather than later 😎
2:36 super true. I’m only 65kg but run a 450 lb spring on my enduro rig
Thanks so much!
Best expansion I've seen on choosing the right coil shock!
Thanks! I happen to have a 2019 Devinci Troy as well, so this video let me know exactly what I need for spring rate.
Hey Mike i was just wondering is it possible that you coud do a basic setup video on the dpx2. there is just so much going on and it would be helpful to get a baseline to start friom, your 36 grip 2 video is great btw

Informative and entertaining without sacrificing info, great video as usual.
DAMN!, i want that, a battery operated IMac 😂
LOL
bahahahaha
I thought I like coil until I watched this video. I have so much anxiety about choosing the right spring rate now.
Might just be safer to stick to air! 😂 -Tor

thanks a lot for the video, i just bought my first downhill bike and i realised my spring is 100 pounds to high
At least that is an easy fix now!
@TheLostCo can you make a video about spring rate and all that stuff for coil forks/front suspension also?
Front suspension that has a coil/spring inside instead of air
Thanks so much for the help! I am looking for a new coil and this helps heaps👍🏻
Watching this i figure out what spring i needed
Awesome video very informative and no B.S. but still entertaining too. Much appreciated xxx
The commencal is like a 1 to 10 I bottom out every time with a 600# spring.
I want to use coil springs to dampen my 4 stroke motor vibration on the motor mount. Trying to make the Cadillac of motorised bicycle rides :)
E-bikes require a heavier spring rate for the motor and battery and the orange springs sag out after 6 months but they are light and look good.
very helpful. big thanks
Hi

This is motocross logic and I love it 🙌🏻
It was so helpful thx mate
Oh shoot those bikes are cool! I want one lol. How much for an entry level one that has a coil spring system?
Love my Sprindex!
you deserve more views
Did you guys try the ripmo af with a jade x? Ordered mine with a 550 spring, I'm 200lbs riding ready! Can't wait to try it out
PL MTB I have a ripmo af with a jade x. I’m 180 kitted up (172ish without) with a 450# spring

What is the disadvantages of replacing a linear spring with a progressive spring ?
such a helpful video. thank you!
I want a progressive mrp spring on my fox coil, run a 400x2.80 and it seems too firm off the top end and bottoms out a little easy
Great info bud!
