RockShox Quadra 21R Shocks/Fork Service - Disassembly/Clean/Lube/Assembly

- I tear down, clean, lubricate some RockShox Quadra 21R shocks. They were working fine, but had almost no lubrication at all. General maintenance. If the elastomers had been bad, I could have replaced them using a rebuild kit. Another company makes springs to replace the elastomers. But the elastomers in these shocks were okay. I used Slickoleum for lubrication in these Rock Shox.
The extra long hex socket I used was part of this set:

* 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.

Sorry to be offtopic but does any of you know of a way to log back into an Instagram account??
I was dumb lost my account password. I would love any assistance you can offer me.
You do a great job of explaining each step. You don't assume people know anything by skipping ahead, which I love. Camera work is flawless. Tool size and explanations of them are also very clear and essential.
@13:50 Service every 25 hours of use. Its been probably 25 years since the fork I'm working on was last serviced. Great video as always, thanks RJ!
Thanks so much for these videos, I did everything you demonstrated on my 1995 Gary Fisher Hoo Koo E Koo, the fork was stuck solid, now it works nicely. Really enjoying the bike again. Had to cobble together that extended 5mm hex tool from bits and bobs from the local hardware store.
This is the set I have: www.amazon.com/exec/obidos/ASIN/B001NT2LK4/ref=nosim/youtube25-20
Considering buying my first MountainBike on Craigslist and I know it'll need to some maintenance. Thanks for all these great videos, you are a fantastic teacher, RJ!
It's great I always wanted to see the quadre from the inside and there was no opportunity. Thanks
I just ordered new elastomers for my 21r shocks. They were on my 1990 giant ATX880. Can't wait till they get here. I had to order them from a place in Arizona.
The old elastomers are disintegrating, so they may take a little work getting out. These forks never been serviced. I know the first 2 owners personally, and they never did it. The bike sat in a bedroom and garage for years and years before i bought it from my friends. I hope these 30 plus year old elastomers come out easier then i expect them to.
People mention the spring replacement, i don't believe theyvare available. I could only find the elastomers at one place. Mine were ordered based on my weight.
Thanks for the video. I needed to fix a Quadra 10 fork (similar build to the 21R) and this video helped me. The fork moves freely now.
I have a quadra that feels like its completely locked out. No travel at all. Could it possibly help to do this? id rather not put money into it with a rebuild kit..
Thanks, my elastomers are powder, looks like a spring kit and an hour's work would do it with the right tools. That saves me some money. Great video!
Thanks I just bought a schwinn with this shox did not know why I was having a problem with them.
The spelling of the grease used is Slickoleum. Thanks for the great video.
That old time when you didnt have to put 3 types of different oils on your fork, and when servicing it wasnt doing a mess... :D
Ben June, I leave them on there to protect the stanchions from dirt.
nothing like the old elastomer forks for the 90's, my favaroites were always the CNC machined Manitou's they just looked sexier than rock shox equivalent quad series
I just replaced the elastomers in my manitou answer 1 last night. What I thought was grease was actually old elastomers that were degraded from being so old
Wow!
Hi,i have a answer manitou mach5 sx,if someday you put a video of this fork,i wil be really hapy!Thanks for share your videos!
I'm having an issue with the 5mm allen socket. Mine tapers down to 5mm and doesn't go through the hole far enough to turn the bolt. How much past the hole is the bolt because I can't seem to find a single 5mm socket that is as long as the one you have.
I just acquired a Gary Fisher with the Rockshox Quadra 21R's. When servicing the front forks, is it recommended to replace the original elastomers with springs, or simply replace with new elastomers instead?
Would you happen to have a link to the aftermarket springs you mentioned?
RJ do you need to leave those black rubber plastic cover sleeves on the fork? Or can you just let the metal stanchions breathe? Thanks
RJ great video thank you very helpful! Now are most forks set up the same way?
653jpk219 Some are, some aren't.
Friend gave me bike with these forks. Seized no movement at all. Took out elastomers and cannot loosen 5mm whatever is down there. Trek 8000 bike. Not sure wht to do next.
Hey, I like your video. You show and explain it all very well. I've got an old Diamond Back Ascent MTB with Rock Shox Quadra 21R on it. I just followed your initial steps on how to pull it apart, but when I got to removing the (you called it the stack), well there was no stack at all inside mine... just a plastic piece (kinda like first part of stack), then a long metal rod came out. Hmm, not sure what to do now. I did take my bike for service last year, but they told me that the Rock Shox are completely stuffed and can't be repaired and that I should buy new shocks. Last year I was thinking that it would cost me a bit too much to be spending so much on such an old bike, but now I'm thinking that I probably do need to go out and buy new shockers. Do you know what would be the equivalent (size, etc.) for these shockers for new shockers? Would love to hear your feedback. Thanks. :-)
Shockers? You mean elastomers? I don't know the size. www.suspensionforkparts.net/eshop/rock-shox.html?page=all
it would be brill if you ever get chance to service a pair or suntour m series suspension forks
liam bishop If I find any.
i cant even see my 5mm bolt down there it looks flat like it isnt there? I have to get some thing down there and try and clean it better my compressed air didnt do it.
Hey RJ, do you have any videos on servicing shocks that use air suspension? I recently got a pair of RockShox Mag 21, but I haven't seen anything on overhauling them, I have found the manual to overhaul them online, but your videos are much more informative.
Not yet. I think I have a bike at home with some of those that I was planning to overhaul. So at some point when I get time.
Good one. I think i'll give my 1995 RS Judy's their first service.
a0667318 TThe Judy's might be different. Not sure off hand. I have some Judy's that I bought recently, maybe I will do something with those.
RJ The Bike Guy seems like this spring everywhere I go I am finding dirtcheap/ free Judys, picked up 4 sets so the video was very timely....
i enjoy your how to vids rj,i have rst shocks on my trek 3700 that need a little tlc like grease,they are the original shocks and i wonder if just lubing them would work instead of taking them apart? pull up the grommet and spray some good lube down the shafts and replace the grommet and push down to get the insides good and lubed
speedjunkie66 That might help some. I really recommend using the proper fork grease. I have a video tearing apart some RST shocks here: ruclips.net/video/d534ilYCaMk/видео.html
RJ The Bike Guy yeah i saw that one,thanks
Great video. I have the Q21R on my 1994 Bridgestone MB-3 Cro-moly and Ritchey Logic. A this moment the Q21R are totally dead. Looking forward to the rebuild. Tht said, I am still POed at myself for taking off the rigid Ritchey fork 25 years ago, (and threw it away..) cuz I 'had to have shocks', but nonetheless a great bike anyways...
big touble. My Elastomers are so old and dead they have turned to clay. only the top three sections of the stack came out. It is literally clay. How can I get the rest out, without destroying the inside of the tubes? I think i will need some really severe long tweezers tool to try to pull the nub on each plastic section out, then dig out the clay? What a mess. I was so ready to have an easy change out, and go riding...
@@dean4559 I'm working on one with clay or mud or something halfway down I am considering running a long drill down to clear what remains and then put a gas car hood strut inside where the elastomers once were
@@keithstone6766 Hi Keith. You need to get this tool I found. It is a triple jointed needle nosed plier. I found it at Lowes. its about 10 inches long more or less ( i don't have it in front of me). perfect tool for what we have to do here. That way you can actually reach down all the way into the tube and you are able to get a grip on every piece of the elastomer stack and pull it out. It takes patience, and a good head mounted flashlight helps too, so you can see down the tube. The pliers allowed me to basically pull everything out. Then I used some mineral spirits as a solvent with an old toothbrush and was able to clean out the remaining crud without damaging the inside of the tube. It took time and patience to get a grip on every piece, but you are very satisfied when its complete. I also located replacement elastomers at an online bike parts supplier. I was able to salvage the plastic spacers in between, but i assume those could be had if necessary. The shocks now are as good as new, and remarkably good. I am having a great time on that old, but rebuilt, classic bike. Good luck.
@@keithstone6766 Keith, do a google search for Irwin vise-grip compound long reach pliers. Thats what i used to get into the bottom sections of the tube. they are slim enough to get into the tube, and you can open them just enough to grab a hold of the stack parts. thats the key. well worth the 15$. considering what they will do.
He man just saw this video after searching for information on these shocks. Great video exactly what I needed. Unfortunately my shocks are toast, the elastic rubbers are gone and the forks are seized but having watched your video I think I can sort having watched your video but need either new elastic components or the springs you mentioned. Are either of these component available to ship to the UK. Many thanks great video.
Shrug. You will have to shop around to see if you can find replacements. No idea if these guys ship there: www.suspensionforkparts.net/eshop/rock-shox.html
@@RJTheBikeGuy is there a change you have the link of spring replacement for the elastomers?
@@rhuishin6719 Nope.
great video, do you have any videos to service RockShox Dart 1 came off a 2008 MTBike?
svcruz No, I haven't done one of those yet.
Hi I recently purchased a nice Rock Shox Quadra 21R. Would you recommend either a replacement of the Elastomers from suspension Fork Parts or SRP Steed Springs? Thanks for your time and opinion. Great review video!👌🏼
Did you fix your fork? Curious about how it went as I too have an old Quadra 21R. My elastomers look to be in decent shape so I'm hoping to not change them.
Hi, yes I did fix my fork. I installed new SRP Steed Springs and the fork is working perfectly!👌🏼
@@sihectorc are the springs instead of elastomers?? like you can get either?
Where can I get brand new elastomers or who is that company tha makes springs for it? Great video by the way
There are companies like "Suspension Fork Parts" (or also Shockcraft based in NZ) that may carry old stock. In the worse case, you may have to try make your own from solid rubber rod (try McMaster-Carr), but they wont work the same. Its an obsolete technology for forks.
Perfect thanks
thank you
Also, I have a 95 Judy XC Cartridge system fork with oil dampener. I read a manual on refilling the cartridges with oil, but I'm worried they are just going to leak all over the place.
I can't help you there. If they are going to leak, they are going to leak. You might be able to get parts, but probably not.
Yeah, I'm just worried about buying elastomers or springs for them and they end up leaking
nice sox
My electric scooter front fork is similar to this fork as far as components. How would you increase the dampening on the current setup? Replace the spring? If so, how do you measure what you’d need and where would you order from? Mine is a 14 inch Chinese fork and bottoms out on bumps so I’m looking for an alternative to factory.
Shrug. Maybe get a better fork.
Why have the same oak leaves been on your garage floor for like 10 years? ;) I have an old RockShox Q5 that I'm going to refurbish using your tips - Thanks
They haven't been. I routinely sweep them out, and the wind blows new ones in.
old rock sox fork extreme resistence fork.
God I miss the 90s
Hello. I have this fork. I want to know if I could find a rebuild kit? Do you hace the part id? Thanks
I do not know if the parts are available.
I have tried 3 different 5mm hex extension sockets. The tip is 5mm, but the shaft is 6mm. It doesn't fit through the hole. Only the tip goes through. Where did you get your socket? Will the T handle 5 mm work for loosening, or are they too weak?
This is what I used. www.amazon.com/exec/obidos/ASIN/B001NT2LK4/ref=nosim/youtube25-20
A T handle 5mm might work if it's not too tight.
Thank you!
I see this time you left the two lowers together. And this fork has the elastomer stacks, not the one-piece ones.
Do you have a Rock Shox Magnesium 21 with which you can do another video? I have one who can sure use some love, and I'm too afraid to open it up, since I don't know shit about forks. Thanks and nice videos
I have a couple of them.
@@RJTheBikeGuy Is there a video where you service one? If not a Mag 21, what would be the difference with? I've heard that Rock Shox Mag and Quadra are quite similar.
Thanks
Not sure. I have a Mag 10 and it's an air fork. Not sure about the Mag21. I think Mag is Magnesium. So maybe a Mag 21 is similar to a Quadra 21, but magnesium. IDK.
How can I find replacement elastomers for these shocks
Try suspensionforkparts.net.
I have a Q 21r that is about bottomed out when tire is attached --very little action--when bike is pulled up from bars off ground, wheel and fork just sag back down slowly. Worth tearing it apart and cleaning to resolve issue or should I just look for a replacement? Thanks!
What have you got to lose? Tear it down.
@@RJTheBikeGuy True---I went ahead and broke it down. Seems to me that fork on this rebuilt 97 Specialized Hardrock was either heavily used in dirt OR was in a flood. The stanchions inside were caked in mud...the elastomers prob need to be replaced. Thanks for the videos!
Hey how much is the suspension in mm do u know
@@Spark_plugs_without_the_sparks according to specs, I believe about 80mm
is there any way to buy somewere those fork boots...i have an old rockshok fork too...i do regular service but I've missing those fork boots...just to help extend their lifetime....greetings. ;)
Not that I know of. You can try ebay. Or try these:

@@RJTheBikeGuy thnks so much friend, first i `ll try with the 5mm ;))
Is there any form of damping?
The elastomers do that
Where can you find replacement fork boots?
If you find them, let me know. You can try these: www.amazon.com/exec/obidos/ASIN/B0010W3N74/ref=nosim/youtube25-20
I think I will try taking the forks off and sliding an inner tub up the fork.
where to find rimes for back of my 26 in bike i nee rime
Bike shop, ebay craigslist, amazon. I am not a shopping service.
Does this work for dried elastomers?
No. They are dead. Replace them. Or replace the fork. And before you ask, you have to do your own shopping.
