Suntour XCT V2 Fork Service - Disassemble/Clean/Lube/Re-assemble

- I show how to tear down, clean, lubricate and rebuild Suntour XCT (SF10-XCT-V2) forks/shocks. Periodic maintenance will help prolong the life of the fork and maintain performance. Basic service to keep your suspension working and from becoming stiff or frozen. I bought this fork on craigslist for $20. The XCT fork models have varied over the years. This fork is a SF10-XCT-V2-P-26-80. The bike is a 2010 Specialized Hardrock.
There are different versions of XCT forks. This is an SF10. If yours has a lockout, you have a different version. You might check out my video overhauling an XCR fork that has a lockout:

The part number for the plastic sleeve is FEE460-10.

* Use grease made for forks. I use Slickoleum which is also sold under the name Slick Honey. You can also use SRAM Butter or Judy Butter. If the fork uses oil, use the proper fork oil. Use of a grease/oil not made specifically for forks can damage the plastic/polyurethane parts, or otherwise leave the fork not working properly.

Love all your videos bro
Keep up the good work
hello...
um i just want to ask a question cuz i want to know if i can install a fork sus on a retro rigid quilstem mtb its a chevaux mtb thanks if u can answer this :)
@@tito_ribin Probably, but they are longer and will raise the front end of the bike, changing the geometry. So it may ride funny.
@@RJTheBikeGuy well ill guess il just stay in rigid fork thanks for answering
Rj pls. Solve this problem
My bike won't change to lower gear(bigger cog) but can change to lower gear(smaller cog)?
please read this!
Watched This video. Then ordered parts from suntour. Quick delivery 4days, comes with grease/an preload tool. Thanks RJ.
I bought a specialized hard rock today from a friend that needed money. I know $200 is way to much but I am a softy. The bike is a reck. I love this Vedic because the front forks are the exact front forks on my new purchase. I have big plans for my rebuild. I plan to follow you step by step.
I found a bike in a trash can. It's from 1996. Only a rear tire needs to be replaced.
I like older bikes from 80's and 90's. They are very simple to maintain.
RJ thanks for another great and informative video. Can not count the number of times I use your instructional videos to fix my bike. Cheers
Great vid.
RJ. Here's a cheap hack that doesn't seem to get a lot of mention.
Look up plumbers tape or silicone tape. Usually its 1-inch wide and come in rolls. I bought a 10 foot roll in black (in adhesives aisle) at home depot for $4.95. wrap around chainstay to prevent chain slap. It only sticks to itself and pretty thick. A little prettier than old tire tube and zip ties. Enough to do 3 bikes i think.
I notice these forks have a serial number. This reveals some information to the person who understand some basics. Fork travel, where it's made and of course serial. You may have to contact SR Suntour for advice on the part numbers like I did. One of my forks I bought New Old Stock didn't include a brake hose clamp, so I finally found a dealer than did sell them and ordered 2 of them. I may lose one in the future, or break it. but cheap.
Really helpful.
As always another great informative and helpful video. Im sure it will help many me including. Keep up the great work you do, all the best Andy
RJ's the best..!
Simple clearcut instruction 👍
Very informative as always!
Love all your videos bro
Keep up the good work
Thanks for upload this video meistr RJ!!
This helped me a lot! The Suntour XCT V3 fork is similar but with only one side bolted at the bottom.
Great video RJ. I have these same forks on the bike I'm working on. I think I'm gonna have to perform this task very soon as well.
Nice one! Easy to follow.
Love your vids sir,very informative👍helps alot👏
Hey that fork is in pretty good shape due its age (SF10 = 2010) ! No rust no dust, nice.
THANKS! You saved me some money on a tune up!
excellent video once again
I know my limits and for the most part would never attempt the work you do but the videos are always entertaining to watch.
Actually, the information here is enough for the average person to take on. There were no bearing settings, or pre-load adjustments for anything. Just loosen parts, take note, clean, regrease and install. But don't over do it.
The brake lever arms you could just unbolt and put to the side and they will reattach without further adjustment.
Thanks for your reply. I saved your video. If I ever have to work on a fork I'll watch it again. BTW, my bike only has one spring. Thanks for showing how to ID it.
Thank you very much for teaching me how to do it. Saludos desde Costa Rica. Pura Vida.
Great video!
i never would have guessed there was only 1 coil...and only 1 bolt...
Crappy OEM fork, not suitable for mountain biking. Mostly there because people like the idea of suspension (but not the cost of an air fork)
@@MrJonas2255 i see that, but even other coild forks have 2...i just bought a new bike with an xct fork...wont see trails though...just commuting
That's what I thought when I opened one for the first time but mine have 2 bolts, I broke the one without the spring because it was stuck and eaten by rust and corrosion and now I have a fork with 1 spring and 1 bolt just like the one in this video.
@@paullmight42 I think usually forks will have the spring in one fork leg (whether an air or coil spring) and the damping parts in the other (compression and/or rebound damping, if they have these at all). Since this fork has no damping there's nothing in the other leg, but the other coiled forks you've seen with two bolts might have had damping parts in the other leg that needed to be bolted in order to slide with the lowers.
@@MrJonas2255 How many times should i say this, it's not about air, it's about having a damper. Coil is just fine.
Got the same fork model,done step by step like in the movie fork works like new,thanku and sorry if bad english.
Благодарю за информацию 👍
Good job!
Awesome sir
Thank you!
I enjoy your videos. It's awesome to show people how to work on low end gear. Just curious when your going to work on a real fork. RockShox SID? Fox 36?
I like your vids it is very detailed ☺️☺️☺️
Love it.
I can’t imagine that a marine grade bearing grease would damage the plastic parts. However, even without damaging the fork it still probably wouldn’t give the same performance as slickoleum or Judy butter. Just another option if you’re really on a tight budget.
very helpful..
Nice bike
Tried this with a pair of suntour, had to throw them away... very difficult job you make it look easy :)
It's really not that hard.
Probably you don't have enough patience.
Like this fork
Hi RJ, please show us sometime a SR fork with oil cartridge and maybe with remote lockout repair/assembly/disassembly tutorial.
فيديو جيد شكرا لك
First!
Second!
Great vid! Can you do one for pneumatic forks?
Hi RJ. Love your channel. I have the suntout xct v2 and using your video to service my forks along with you. However I find the rubber elastomer inside my spring is in 3 pieces. I guess it’s broken. I can’t find a replacement and wondering if it’s still ok to use with the broken elastomer? Do you have any advice? Thank you.
Great Video! I just got a Hotrock 24 (2011, 21 speed) for my child, it has an sr suntour sf11-xct-jr-24 fork and I'm wondering if the process and parts for the process would be the same cuz its just 1 year older?
could you please test if carbon paste (anti slip) would be any good on steel/aluminum bikes.
Hey I love your videos can you please make a video on how to fix wobbly fork
It would vary by fork. If you have a Suntour like this, replace the plastic sleeves.
Do you have to twist the plastic sleeves back
These are the same as what I have on my Trek 3700. I got run over by a car not long ago, so it will be awhile before I am riding again, but a little project like this might be fun in the meantime.
Sorry. Get moving again as soon as your broken parts are healed. I was run over, had a truck tread "tattoo" from my right butt to my left shoulder. Nothing important broken. Rehabbed every day until I was exhausted (nothing else to do). Bicycling got me back to health, but I needed to do more sideways movements (but didn't,) so I have a few issues. It's been 2.5 years and I am doing great. Don't let the initial pain hold you back. Good luck.
@@bob-ny6kn I got pretty lucky and kind of rode the hood of the car, and almost got away with just gnarly road rash but just my left left leg got caught under the front right wheel while it was spinning...my ankle is pretty much metal and screws, with some pretty large surgery scars on either side...maybe about 40 or so staples...I just recently got out of a cast, which I had for about 3 months or so...then an air cast for another month...so this is my first month I can take the air cast off and start walking around. My foot is always going to be a little messed up, my ankle more so, but the road rash is long gone, and I am up and able to walk, even without a cane...though I need the cane if I have to walk anywhere too far. I am hopeful I will get most of the movement back in time...I always look at Steve-o, cause he had a similar ankle surgery and he's, well, still Steve-O lol I think I'll be able to ride before the winter hits...fingers crossed. Thanks for your comment and encouragement...getting hit by a car sucks...especially when it was a random ex-girlfriend doing it intentionally after me not speaking to her for over a year...so yeah...that's what happened lol
@@AaronHendu Random ex "accident" - Hahaha. Are we twins? Know what pain is good to chase and what pain is telling you to have a rest. On your worst days, find your inner strength or a good friend and just get past the bump. LOL. For sure. You will be back, and stronger.
For me the preload knob moves clockwise/anticlockwise for about 2-3mm. That's not normal right?
When I try to unscrew it, the whole knob that keeps the coil goes out. I've tried to oil it, but with no success. Any tips on what should I do?
Yes another fork service 🙂
Hi Rj I'm watching your videos for a while i love videos they are very informative and instructional! I have an old vintage bike that i love and i was wondering if it is possibile to make an old vintage front suspension blockable?
Not really. Plenty of rigid bikes out there. Or get a suspension corrected rigid fork.
Sorry i think i didn't express myself 😅 I have a rigid vintage bike i was wondering if I could make an old suspended fork bloccable for uphills and climbs like the newe ones
@@SupadaiduS Lock out? No.
How long is the extension that it is required to reach the internal bolt?
Unfortunately, Sr Suntour does not make the sleeves for these model forks anymore. The current sleeves have a new design. So be sure to take the sleeves out carefully!
I see some other places that have them. Part number FEE460-10.
It went together easily in less than an hour. th-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Make sure the front fork is forward or the pedals will hit the front tire. Tires are both a little soft so it needs air before I ride it. The rear wheel didn't come with a clamp regular bolts hold it on. The front had the clamp. No scratches out of box. Rims are a little off with a slight wobble. They could have spent more time with the spoke tool fixing the run out. So far out of the box I'm happy with it. I did replace the pedals with a nice aftermarket set. After riding it a bit my A$$ is a bit sore so I ordered another seat. Overall I'm nearly 60 and didn't ride a bike in 30 years. I like my new 29" Schwinn. It will be used for casual rides with my friend.
Hello from massachusetts, so i changed out my bearing in my bottom bracket tightened it up and there is still play and it seems really tight is there a reason why there could be some play in it? thanks Raj
I can't tell you. I haven't worked on your bike. I don't know how it could be tight AND and play.
mine probably has two coil because there are nut sticking out on both forks. SUNTOUR XCE28.
thanks for the tutorial.
There are different variations. I have a handful Suntour fork vids.
Alternatively, your fork might have damping circuits in the other leg (these don't provide the *support* for the suspension that the spring does, but help to fine-tune the *rate* at which the forks compress and rebound). Often forks that have damping will have the spring in one leg and the dampers in the other.
Seeing how they're made, it's no wonder they're crappy shocks. They look stiff (maybe stiffer) as hell even after all that work.
Hello rj you would never guess what happed to me, my property suffered a massive lightning strike two weeks ago fire damage, house unable to live in for 12 months But cycle workshop is ok It took 8 fire engines to get it under control.
Ouch!!! Be safe!
Hi Sir, I do have a suntour bike with 27 x 1 1/4 wheels. What is the alternative wheel size for this if I want to change it to different size? Thank you.
Suntour didn't make bikes as far as I know. This fork will not work for a 27" wheel. The brakes wouldn't hit the rim. 27" wheels are antiques. Better off getting a new bike to start with.
It will be great if you service a fork XCM32 with remote lockout as it's widely used on budget bike.
I think it is similar to the XCR. th-cam.com/video/BUgt96qfV68/w-d-xo.html
@@RJTheBikeGuy ya maybe but it has a remote lockout.
@@LetsDiscoverMauritius The remote lock out is just a different thing that snaps on has a cable.
Hello, great video.
I have a Raleigh bike that cost me 47$ and i love it, but it's got a Suntour XCT V2 in very bad shape. Can you recommend a fork from Aliexpress that can replace it ?
You gotta do your own research.
👍🏻👏👌👋
How can one know what type/size of fork neck does a bike have without taking it apart?
its just a spring no shock absorber like on cars? So just the friction slows the spring down to prevent bouncing?
Rubber thing inside the spring acts as a damper.
My preload has been broke.. how to remove it... Any idea?
I really love your videos but I have a problem with my 1979 Peugeot ps10. So I replaced the old original simplex chain (it was due to break) with a Shimano road bike chain and it rubs on the front derailleur on the smallest cog on the rear and the smallest up front( its a 2x5) any solutions you may have or is it normal? ( I’m not running indexed shifters so I adjust the front so that it doesn’t rub when I’m using that gear combination)
That is called cross chaining. You are not supposed to ride in small/small or big/big combinations in the first place. Learn to shift properly.
RJ The Bike Guy lol so I have been the problem this whole time 😂.thanks for the advise anyways and love your videos keep em up
RJ The Bike Guy man I went for a test ride it works perfectly. Just have to get used from riding my old single speed cruiser to properly riding a road bike.thanks again
Can I just clean and regrease the spring?
i got that bike from you, can so if I wanted to set the shocks do I need that tool or do I just use my fingers to twist the dial thing
You just turn the preload adjuster with your fingers. They don't make a huge difference.
Ok thanks, I was doing that but I didn't notice a difference
hi RJ sensei, I have a problem, my suspension is exaclty like that, but that preloader adjuster cap is stuck inside and I cannot remove even with that plastic tool you use, if I try to use a metal wrench the plastic starts to wearing out... how can I solve this and save my suspension fork...
I don't know. You might have to destroy the adjuster cap to get it out, and replace it. Maybe vise grips.
why can't i find any with v brakes? can you add the stand offs for the v brakes to ones that don't have it?
Not looking hard enough. No you can't.
Only because I can't leave things alone, are there any upgrades that can be done?
Well, you can replace it with a better fork.
Is a Trek mountain bike 1000 that has the composted frame about the same to do maintenance on the forks? What about the shock rock for the rear end and the swivel rear frame? Thank you for any information. I need to learn the maintenance on my mountain bike, I use to take it in but now I am retired and the maintenance cost is up to around 180 dollars.
It's the brand/model of the fork, not the bike. Different forks are different. If your bike has a Suntour XCT V2 fork, then this video is relevant. I have other fork videos too. I don't have any for rear shocks really.
@@RJTheBikeGuy are schwinn mountain bikes ok in your opinion from Walmart
@@Blu-Man Pretty much any bike from Walmart/Target is junk. There is a reason they can sell them for $100-200. Because they are cheap junk made with cheap junk parts. They will break.
@@RJTheBikeGuy well I'll return it get money back and go to a bike shop for better quality
I realized after I serviced my fork that my sleeves were moving 360 should I open back the fork to double check ?
Yes. They were probably not snapped into place.
@@RJTheBikeGuy I pushed on them and they were snapped into place , i left them with the back part that is supposed to snap in in the right place hope everything will work okey
What happens if the clip broke on the sleve
I'm fitting a set for a 50's ev bike for the disk and the old bearings will line up in balloon bike headsets. No jumping or hard riding though. LOL!
Hey make a video on fixing hydraulic brakes mine is spilling oil in the bleed port
Problems like that would be specific to that brake/lever. I do not have a solution. You will have to research. Could be something is loose.
Can anyone give an opinion on the breezer mountain bikes ?
Please make a video about fitting a 1 1/8" fork to a 1" frame i heard it is possible
Good luck with that! LOL!
6:00
RJ, you need to get yourself a bottle brush from a brew shop.
I have bottle brushes. They get greasy and hard to clean. They just don't work as well.
@@RJTheBikeGuy
Great experienced advise as always!
Hey men can i use threadless headset on threaded fork?
No.
Hi! I rly Like Ur Videos
But can u pls make a video on how seperate shifters and brake levers, I want to install hydraulic brakes in my cycle but the brake came integrated with the shifters.....Can U Pls Tell me how to seperate them?
You can't. Gotta buy separate shifters and brakes.
@@RJTheBikeGuy oh ok Thanks!
Hello RJ, sorry to be a bother but do you know how to measure a BMX Bottom bracket?
Many BMX bikes have Ashtabula one piece cranks and the bottom bracket is standard.
@@RJTheBikeGuy Thank you
+rj the bike guy seems a bit strange that theres only 1 spring in the fork,wouldnt that unbalance the fork?,1 of the upper tubes is shorter too which could unbalance the fork even more?
Why didnt u put threadlock on the 2 nuts in the left side surely they could shake loose over time?
Most forks have coil/air chamber only in the left leg. The right leg has the damper / lockout mechanism, or simply nothing as sou seen in the video. :) No need te threadlock the nuts, they wont get looser. I had a suntour XCM fork fewer years ago (SF12 version) wich has two softer coils in both legs, one in the left and one in the right. It was almost 3 kgs
There was no sign there was threadlocker on there in the first place.
11:50 ☻
Where can I order the rubber seals?
Maybe www.srsuntour.us/collections/fork-parts
You have to do your own shopping.
Could you use WD 40 for the suspension forks
This was answered in the video.
i have a 2013 trek and my fork was sticky and would only compress and come back up with persuasion
This vid helped
I have a very weird sound on my xcm when I jump something it makes a strange noise
These forks are not really made for jumping.
@@RJTheBikeGuy yeah but can't afford a new one for now and want to fix it
If it bangs on rebound there's nothing you can do because it doesn't have rebound damping.
@@no-prophet ok thanks
3:33 THATS what she said. 🤣
Hello...I'd like to thank you for your videos....
I have a question about replacing the inner spring shocks with air/spring shocks without changing the fork body.
spring have only one?
Yes.
I hate suspension forks with a passion. Never mess with them.
Also, i never put threadlocker on brake bolts. I’ m sure it’s good safe practice and’manufacturers do it but i’ve never heard or seen one unscrewing itself from it’s location.
.
BE CAREFUL SOME GAS CHARGE SHOCKS CAN SHOOT OUT LIKE A SHOT GUN SLUG THIS OLDER CHEAP FORK IS NOT DANGEROUS BUT SOME BETTER FORKS SHOULD NOT BE MESSED WITH ! THIS CHEAP FORK EVEN WHEN ITS WORKING 100 % IS DANGEROUS JUNK PERFORMANCE WISE BETTER OFF DRILLING THROUGH IT AND LOCKING IT OUT .
who in their right mind would go and buy replacement parts for a plastic tube LOL that is covered in grease how would it wear out
seriously what a joke
What threads does suntour use on the v-brakes???
