Just rebuilt my mom-in-laws mongoose switchback that had been sitting for years in the elements. It now is ridable but I got some extra bonus features for her and her Chihuahua
I've noticed 2 things watching you. 1. You a really good at working on bikes and explaining what you are doing. 2. Someone drinks a lot of soft drink at your house.
Thank you for taking the time. Renovated a cheap Suntour front fork that didn't even have real nuts on the bottom. No room for a polygrip, no hex, nothing. I had to WELD on real nuts on top of the round/blank ones just to get them off and replace them... If you get stuck at this without a welder, drilling a hole in the side of the round/blank/factory nuts might do it (which you then use to turn them). Careful not to damage the threads of the bolts. If your suspension is top-grade, a lint-free cloth is beneficial, most shocks take 30cc's of oil in each tube. Purpose-made oil is great, but for an old or cheap fork regular car motor oil works too. I found a bottle cleaner brush does great for cleaning the inside of tubes. All the best to you and happy tinkering.
i really liked the video and i really want to see more complicated forks that aren't working fixed by you. i would like to see a more "in depth" video about the basic mechanics for a rebound or a high speed compression cartridge. I would loved for example to see in this video that rebound cartridge opened and explained from top to bottom and then reassembled. You have the basic videos for the "basics in how to fix a bike" but it will be awesome if you can show us how to fix a more technological advanced bike (like a superior suspension cartridge) Keep up the great work, i love your channel!
Foxey Glad to see someone else understands these were never designed for 'boulder level' brutality!-) Using these shocks 4 downhill comps would be akin to driving. 'Modern Day SUV' through a MISSISSIPPI mud pit....why? U R great!-)
Thanks a million for the video.. Used it as a guideline for my 2018 RST Gila 100mm, and it worked flawlessly.. Now I don't need to buy a new fork for a while. If anything, I've made my suspension buttery smooth!! Thank you! . (edit) Also followed and did your DIY preload adjuster cap ratchet socket.. Works like a charm. Brilliant ideas!
I have the 2009 version of the F7. It has RST Gila T5 Pro non-lockout. Cleaned them from your one video and they are what they are. Better than working on Suntour XCM or XCT. Great bike, upgraded whole bike except forks. That's next. Great video thankx
Thank you for making this video! It looks like you had fun. The guys at the bicycle shop said that these forks aren't worth fixing. I say, they aren't worth fixing. 😒
just did the same service on the exact same bike and fork...lol. In my case the hydraulic cartridge was locked out and the adjustment knob didnt do anything...I probably could have just removed the adjustment knob and reset it, but went ahead with the full regrease. I was wondering....have you ever taken apart one of those hydraulic cartridges? it looks possible with the nut at top. I didnt want to risk not being able to put it back together, but wondering what replacing the fluid would do. RST website just shows a replacement with new as part of the service. Would love to see a video of you taking one apart. thanks again.
Hi there ! Im having a problem with my suntour xcm 100 mm fork. It moves front and backwards ate the seals. I already changed the dust seals but its still the same! Im wondering if u have any advice. Greetings And keep up the good job
My cheap Sunsucks (Suntour) front fork didn't even have real nuts on the bottom. No room for a polygrip. I had to WELD on real nuts on top of the round/blank ones just to get them off and replace them. Ridiculous. When I see something like that I get determined to fix it if not ONLY because they don't want me to xD. Feels great sticking it to them so to speak.
Hey RJ, love your videos mate! I have seen all your videos about these rst forks and i have that problem with the spinning bolt. The problem is that I have tried everything you mentioned at your videos exept the impact driver cause i dont have one! Nothing seems to work... Any ideas for unscrew that bolt???? I am working on an old bike (but on good condition) and it doesn't really worth a new fork. Any advice would be much appreciated!!
If you can get the stack out, I think the bolt in the bottom (see @ 10:34) may have a hex fitting that you can grabe from the inside the tube with a long extension.
I've always used a ratchet strap for compressing forks. Hmm, looking at the parts when you pulled it apart, is the cartridge serviceable (needing periodic fluid changes)? Just wondering if those are still friction/MCU damped or are actually hydraulically damped (I know RST makes both styles, although the friction damped ones are more common).
What can I do if those screws down the fork spin freely even if i compress the springs? The suspension is a Zoom with double crown, springs without blocking and 180 mm of travel. Please help me, your videos have been really helpful for me 👌
If you get a really long allen wrench (4, 5, or 6mm), you might be able to take out the stacks and reach down and the other part to keep it from turning. An impact driver combined with compression might work.
Hello from Le Mans FRANCE, thanks for the videos you made. It's very usefull, giving the good way and sometimes new ideas. But mister, watch out your feet !
Hi Rj can you help me I try to clean may RST fork but I had a mistake instead of unscrew the bottom I start to open it on top then I can't remove the lower stanchion
i noticed when you work on front sides of bikes.. like in this case the fork..or front brakes, every time i see that blue thing that prevents handlebars from turning..... its pretty useful... whitout its so annoying somtimes... is this self made or is there one to buy actually...? btw very nice work on that fork !!! ;)
This fork (RST Gila Pro) and the other fork you posted on (RST Gila T5) do not use oil. You need to find instructions for the EXACT fork you have. Not one LIKE the one you have.
Sucks that they take a specialty tool to disassemble. I have some gila plus t7's on an old specialized hardrock sport. They just have a preload adjustment on both the forks. They still move but are super stiff.
why the lockout cap turns only a quarter turn after rebuilt ?? before it was an half turn.... got hands on one of those...im just curious... also think i need to readjust that cap....
probalby yes...mostly of them have a valve that can be opened and closed.. to lock or unlock the fork when its closed, the valve lats no oil trough..so its firm ;)
Hey RJ i Wonder What is the use of the left cap of the barrels, i dont mean the lock cap, but the other one, (which has a + And a -) i Wonder What is the use of that if anyone could Tell me
Great job! I almost watched all of your suspension repair videos and this bike has the same parts that I have on my 2010 TREK 4300. I am waiting for the SRAM silikoneum to asamble it. For those who are interested, the preload adjuster, the special tool from RST and the RST Dust Seal Kit can be found on the link below. They are little pricey with the shipping but couldn't find a US seller.

I have the same bike. Hopefully you've figured it out, but if not, here you go. . The preload is a very small adjustment, not too much is really done. It still does affect the suspension, but only by a little
Can anyone tell me how to possibly fix my bike? I bought a full suspension mtb and got it last summer. I assembled everything and took it for a test ride. I was really upset because both the front suspension and rear suspension were squeaking. I went to the store and bought some lubricant and sprayed it on the rear and the front suspension. The rear suspension was fine forever after this but the front suspension was not. I later took it apart greased it and put it back together. It was fine for a while but it later came back I repeated this 3 or 4 times since I bought it last year, but the squeak just keeps coming back and its soooooo annoying. My front fork is a sr suntour m3030. Thanks.
RJ The Bike Guy i just found your channel,and is great,on the lock area is difrent,im gonna see if i could do it,i have a tyax mongoose 2009,by the way i like your channel

Thank you for making this video! It looks like you had fun. The guys at the bicycle shop said that these forks aren't worth fixing. I say, they aren't worth fixing. 😒
If they are good shape, then simple maintenance is warranted.
After seeing how these are made I’m wondering if there was any point or benefit to cleaning them other than polishing the chrome.
So happy I fuond your video just in mid of disassembling the same fork :D for left leg, also just pliers with some fabric wrapped work nicely
Also right leg I unscrewed just rotating that lock cap :D
Most informative video on TH-cam 👌🏻 👍🏻
Very detailed overhaul, nice job...
“Have no friends”😂😂
😂😂
1:11 let's just say I'm working alone, social distancing 🤣
Nice 👍 I have rst saturn and it is almost the same. Need to figure out how to bring back lock out option- doesn’t work after my overhaul
just did the same service on the exact same bike and fork...lol.

hello, thank you for your video. I got a bit of play in mine. Are there sleeves/ in the lowers, too like in the suntours?
I never done before it looks fun it perfect the bike 🚲
Thanks RJ really enjoyed that video i have learned so much from you very grateful.
"If you are working alone or have no friends." This is definitely a video made for me lol
Nice. Like all your vids😊
Thank you Mr. RJ 👍
Fantastic as always!!!
Another great video...as always.
Hell yeah! These are the type on my 4900 that I'll do the same as on my 4600~ Thanks👌🖖⚡️
Hi there ! Im having a problem with my suntour xcm 100 mm fork. It moves front and backwards ate the seals. I already changed the dust seals but its still the same! Im wondering if u have any advice. Greetings And keep up the good job
Dunno. Might be worn out. I think there are bushing in there that may or may not be able to be replaced.
These companies make all these ridiculous special fasteners and tools when they could easily just use standard stuff.
John Smith it’s to stop people fixing stuff and make them buy new stuff
100% true!!

Hey! Do you know what is the stanchion diameter for the dust seals on this fork? Thank you so much!

that is something I learnt thanks
thank u for d video its is the same procudure for the xcr suntour 2016??
A Suntour XCR is a different brand/model fork. So the procedure is likely different.
I would like to know if using high temp silicone paste would suffice.
Hello from Le Mans FRANCE, thanks for the videos you made.
It's very usefull, giving the good way and sometimes new ideas.
But mister, watch out your feet !
Great video RJ, Do you mind making a video on how to increase the travel on suntour M forks?
Probably buy new forks with more travel.
But then your frame was probably designed for the amount of travel of those forks.
Cool project
Hi Rj can you help me I try to clean may RST fork but I had a mistake instead of unscrew the bottom I start to open it on top then I can't remove the lower stanchion
I love that bike it so awesome amazing it looks similar my bike but becarefull
Sehr gut.Danke
I cannot remove the Phillips screw from the lockout Lever. It just keeps spinning! Any ideas how to resolve this problem?
Be careful not to lose any of the mounting hardware, on the floor?
i noticed when you work on front sides of bikes.. like in this case the fork..or front brakes, every time i see that blue thing that prevents handlebars from turning..... its pretty useful... whitout its so annoying somtimes...
is this self made or is there one to buy actually...? btw very nice work on that fork !!! ;)
It got weird when the rope got pulled out but ironed out pretty quick
how can I find the part number or order the part, of the dust seal at the top of my lowers on my RST Gila Plus T-5 forks?
0:20 it`s the screw. If you lose the screw it helps
No. The screw shouldn't be loose. And that wasn't it.
RST = "Rozwal Sobie Twarz" = "Get Your Face Smashed" in Polish :P
Hi! how do you put extra sucide levers on your top bar so you can stop when you dit straight on your cross bike
th-cam.com/video/K2ZgNrS7hSc/w-d-xo.html
great vid bro just keep it up
NICE VIDEO,VERY INTERESTING, THANKS.
So there is no Oil just grease, nice.
Só de ver fazendo já é muito legal
This Fork is like mine, it has an enclosed oil reservoir for lockout and maybe dampening purposes, does the oil Reservoir need to be serviced?
This fork (RST Gila Pro) and the other fork you posted on (RST Gila T5) do not use oil. You need to find instructions for the EXACT fork you have. Not one LIKE the one you have.
RJ The Bike Guy ok your right, mine is a Gila TNL, it seems they don’t make the Gila pro anymore.
Exactly. You need to find instructions for your specific fork.
thank you
Sucks that they take a specialty tool to disassemble. I have some gila plus t7's on an old specialized hardrock sport. They just have a preload adjustment on both the forks. They still move but are super stiff.
Gracias, me sirvió mucho 👍🏼👍🏼👍🏼
why the lockout cap turns only a quarter turn after rebuilt ?? before it was an half turn.... got hands on one of those...im just curious... also think i need to readjust that cap....
It was messed up to begin with. I don't know if a previous owner messed it up or what.
OK, need to find some Marzocchi air forks and do them. The service manuals lost a lot in translation :D
Was the cartridge an oil damper?
probalby yes...mostly of them have a valve that can be opened and closed.. to lock or unlock the fork
when its closed, the valve lats no oil trough..so its firm ;)
The man loves his Pepsi.
Hey RJ i Wonder What is the use of the left cap of the barrels, i dont mean the lock cap, but the other one, (which has a + And a -) i Wonder What is the use of that if anyone could Tell me
Preload.
RJ The Bike Guy thanks, the minus is for a softer suspension And the plus is for a more stiffer suspension? Or the other way
I have some forks like this an the lock out thing is old where would you get a new one or is it even worth it you think help plez
You probably aren't going to find new parts. Maybe buy a used fork and part it out.
hey i need a question! , i cant remove one of the lower screws!! turn on itself . . do you have any solution ?
Did you compress the fork?
And you can go down inside with a tool like in this video: th-cam.com/video/mIrydAhvOns/w-d-xo.htmlm36s
yess i compress at the maximium posible, and the screws turn on very easy on itself. y have not more ideas , please help me =)
thats alot of pepsi
We buy it when it is on sale.
Rust removal hahahha:P
My rst gila has a broken lockout knob..is there any way to replace it?can someone give me a link? Thanks
RST parts are not easy to find.
is lithium grease ok to use instead
th-cam.com/video/5pl-oVYVLvA/w-d-xo.html
Do you know how to reduce the travel of this fork?
Nope.
how'd u know i had no friends?? my Trek has RST 191...i assume its the same to overhaul?

useful & interesting
Where do you find your clients?
What clients? I only work on bikes I buy and friends bikes. I don't have an open shop.
I see. So it is your hobby. But you doing it like a professional.
I have a treck marlin 5 and my preload knob has no effect on the preload when i turn it. Can anyone help?

I would see if you can replace the seals on it. That could be the cause of the sound.
Liam Hangen j think that's what I should do because when I did the maintenance this time it seemed like the seals we messed up. Also thank you.
anonymous I was considering upgrading my bike and that was one of my main upgrades I wanted to do
Is mineral oil a good lube
Not for this.
RJ The Bike Guy i mean for normal lubricatuon
Thanks exelent
my bike doesn't have shocks :(*
Why is each side different?
Some forks are like that.
RJ The Bike Guy love your videos I'm fixing up a early 90s. Schwinn crosscut I found at Goodwill my first bike thanks
My suspension does no lock😑
Did you do everything I did in the video?
RJ The Bike Guy i just found your channel,and is great,on the lock area is difrent,im gonna see if i could do it,i have a tyax mongoose 2009,by the way i like your channel
How much this bike cost?
I got it for $140.
👍👍👍👍😍
Ok
Gila is pronounced "he-la", like Gila Monster ;-)
Well now I am going to pronounce it Guy Lay. :D
Wise ass lol. I've lived in the SW most of my life, I encounter that word a lot. Anyway, nice to see how those forks work.
Lol. Gila means crazy.. or mad or insane in my language.
8:52 Wait What That doesn't make sense
Using a grease made for suspension forks in suspension forks. Yeah, a really crazy idea. SMH. AH
No oil inside! Pure coil spring!
Bruvv,,,Listen,you need to buy some shoes,innit !!!
I hate avid bb7 disc brakes. I know the brakes in the video are bb5 but I assume they are shit too.
I was following along fine until I saw that gang green toe at 17:19. 🤮🤢🤢🤮
