I have a 2018 Cannondale (27.5"-650B) CUJO 3 with SUNTOUR XCR FORKS...are there any upgrades or IS THERE ANYTHING to change for a better ride? so many have told me to just get a new set of forks but the prices are almost what I paid for the entire bike ($1200cdn) & maybe I'd be better off just getting a new $bike$? I love the gearing/set-up for ME on the Cujo but I don't really know any better when it comes to this sport...put 740 km on it since August of 2018 - never jumped it or have done anything except ride on pavement normally due to my back injury BUT I DID GET OUT ON A BIKE with my Dr's OK & have been loving it since!!! YES, I'm sure a full suspension mtb would be better for my back BUT because I'll NEVER be jumping or "downhilling" is it really worth it MONEY wise? Would really love to hear your suggestions.

[@Asthbendriel]

Excellent video guys! I just went through this process a few weeks ago and this is very helpful for anyone in that process. Just as an extra tip: even if tapered is the current standard, there are different "tapered" measurements, so making sure you have the correct headset for the fork you wanna mount is also a must or it simply won't fit. That just happened to me, turns out my previous fork was a straight tube with an adapter to run into my tapered frame and when I tried to get a new headset for the new fork which was tapered, they weren't fitting because my frame was "the shorter" tapered standard 😅 you guys helped me to get the right headset, so thank you very much 😁👌

You can fit tapered fork to a semi integrated head tube (common on entry level frames) that came standard with straight steerer by replacing the bottom cup of the headset. Nukeproof do one called the EX44-40 - B5. This opens up a lot more options for replacement forks.

[@drobotk]

I've always been interested in getting one of these but there doesn't seem to be much info about them anywhere regarding what will fit where etc.

Hey thanks for the video, bike git stolen a couple of months ago and I recently got it back.

Plus 1 on the maker’s mark! ❤️ Got here since I am looking for more information if I can upgrade my Trek Marlin 7 2021 fork from Rockshox Judy to Fox 32. Things I thought off to consider are the axle. Marlins have a QR skewer while Fox32 has a TA. 🤷🏻‍♂️

Qr was the worst, I had to buy a whole new front wheel

[@joshuachin9799]

Great explanation! Can you make a video to compare 2021 RockShox SID SL Ultimate and Fox 32 Factory? I can't made up my mind on which to go for.

[@sheltermutts4185]

Great video. How do I determine the “travel” of an older Giant mountain bike fork? Thanks!

[@DamianNocun]

Hi Bikers, of course content is great and was enjoying to watch, however coming with question :) I have a XC bike, Trek Procaliber and was wondering if RockShox Reba would be a good fork for this bike knowing that SID has many issues. Would you recommend Reba as Judy SL replacement ? Or maybe something different in similar price range ?

[@thecakeisalie7070]

You "can" run a 29er fork for 27.5 frame but since the arch is taller, you lose about 20mm of possible travel per wheel-size. Smaller the wheel, the more travel you get from the same axle-to-crown distance. You can also upgrade your 26er with modern tapered fork but there are many things to consider. If you have an older freeride bike that can use 200mm 26er fork with 570mm axle-to-crown, you can run a 160mm 29er. If you are upgrading a 26er 20x110 DH to a 15x110 Boost you'll need a 5mm brake rotor spacer. Even though the axle width is the same, the designed distance from brake rotor to brake mount is 5mm wider on the 15x110 Boost spec. Also, you'd need to run something with torque cap compatible fork because the 26er 20x110's hub interface diameter is larger than what the 27.5-29er 15x110 hub. Maybe your 26er came with 1.5" headtube - you'll need a reducer top or if it's already running straight 1 1/8 reducer top and bottom, you'll need a 1.5" bottom.

[@invaderzimrocksify]

Well once I blow out the Rhythm 34 on my Stumpjumper I know what to get now 😂 But it has been a great fork for general trail riding.

[@therodenthitman]

Interesting one for you here, I have a 2004 Intense Uzzi SLX with nice upgrades by the previous owner. 200mm hydro discs front and back, dropper post and I've turned it into a mid-drive Ebike and absolutely love it. But I want to upgrade the front fork to something more modern. It's an old Manitou Sherman with the 1.5 inch straight steerer (not sure how much travel) and has the 20x110mm axle with 26 wheels. I'd like to be able to use the front wheel still even a 26 on a 27.5 fork is ok with me. Is it possible to use a fork with a tapered steerer using adapters? Would I just get the appropriate headset? Is it possible to have a bushing fit over a 15x110 to make it be 20x110 enabling me to keep my current wheels?

[@mrfrogg46able]

i have a 2018 GT Avalanche. 9 or 10mm QR. i use a DT swiss 350 with their 10mm QR axle. its great. i have a tapered full integrated head tube. i use a cane creek 44. headset. a rockshox recon tk gold 100mm. i an getting a fox 32 or 34, used. 3 to 4 hundred. fit float 3 position. all the bells n whistles. 120 to 140mm. it fits.

To reduce the travel on an air fork, such as Pike 2015, is it OK to simply increase the sag by reducing air pressure, and possibly adding a token to make it ramp up more? Your thoughts on this would be appreciated ;-))

What is the longest travel fork i could get for a 1 1/18 threadless stem bike? (besides double crown downhill forks)

[@Drago0900]

My bike is from walmart and I have no idea what offset it had but I changed it out for a scrap m3030 due to major failure in the Walmart one. The manufacturer says that the stock fork was 80mm and that a 100mm fork would be fine. Idk it’s just weird. After I changed forks my steering was a bit more responsive but that could be from the fact that there was no play in the stanchions.

[@tobyg4556]

Odd question: could I swap out my current 130 29er forks (with 27.5 wheel, 2.6 tyre) to a 150 27.5 fork (with 27.5 wheel, 2.6 tyre) ?? If axle to crown is very similar, only 3mm difference will it change to geometry very much?

You may set travel more, only adjust the pressure on your fork to lower weight.

I would really like to put a fox 32 xc fork on it but it came stock with a straight steerer tube.

Damper is the same it’s the air spring that defines the travel and I wouldn’t add more than 20mm or your bike will be horrible to ride.

[@JustAGlitchFL]

Another thing, they said 9mm QR, when they meant 5mm QR. A 9mm QR is a standard that Fox stopped using 2 years ago. They had stopped using 5mm QR a long time ago. Whenever you see a cheaper modern bike with QR axles, it is probably the 5mm QR standard. I was confused a while ago, so I measured the QR axles on my road bike, and they were 5mm. I have an older mountain bike, that has a 9mm QR front axle, and a 5mm rear axle. I have never seen a 9mm QR used as a rear axle, but they probably exist somewhere. My friend's Marin Hawk Hill 1 has a 15 mm thru axle on the fork, but uses a 5mm skewer on the back in a bolt through dropout, in some weird combination thing to keep the cost down.

[@JustAGlitchFL]

To clarify, the one they showed is a 5mm QR axle.
