Great work Henry! Never done this service but your video gives me the confidence to give it a go. Great tip regarding removing the bottom out spacer.

Love your videos! Keep making them!

I had a lot of fun taking my 2012 Reba's apart when I got them used this spring. I learned a lot about the duel air system. Problem is my Bike cave / workshop was my front porch and it's now 5 degrees out...

Nice, I’ve never done this service but I will now!

Just what i needed. Thank you !

Thanks for the helpful video now i can try it my self

Just had to get the air out of the neg chamber on my new lyric 170's. Scat a satisfying sound THAT makes 🔊👌😁

Done. Managed the damper too with the help of another video

Perfect. Keep these coming.

Great video Mr Quinney👍 and very helpful, 😀👍

Some important steps missing there from the rockshox service Henry. Especially the orientation of the circlip, MASSIVELY important, one side has smooth edge, one sharp. Sharp MUST go outwards/down. Didnt look like u checked, hope by chance u got it right!

Worth pointing out for anyone with the pre Debonair airshaft the circlip needs to be twisted onto the raised bit. The new design on the debonair is much easier and Henry has obviously done this a few times, don’t despair if it’s more fiddly. If you change travel at the same time the new airshaft is easily worth the extra £/$/€ 10

Great video - Can you please do a service on the damper side of the Pike fork, or is that not really necessary?

@GMBN Tech: that general rule that the air spring has to be longer than the damper shaft is NOT true for all forks. I was upgrading the travel on a customer's 34 Rythm today and the air spring was 10mm longer than the damper. I had spoken to Fox personally to verify that the air spring I was putting in was compatible with the damper but did some serious second guesssing due to this advice! I guess you meant significantly longer, by some margin unbeknownst to me.

Henry you beast! Double dipping too ✌️

What should I say? Thanks! Love you guys!

Hi Henry. Any idea on how to service a 2001 Rockshox Hydra Air SID XC? Planning on tackling it myself. Thanks!

Should you do a damper side service every time you do an airspring service? Or should one be more frequent? Great vid by the way, I wish I had watched this when I did my fork service.

literally swapped to a longer travel air spring 2 weeks ago haha

Can you do a how to on a manitou Mattoc please? Cheers👍

Should one put a little bit of pressure in the air spring before attaching and bolting the lowers on to prevent air in the lowers (and negative chambers) Pleae help

question, how would removing that top out bumper increase your negative air chamber size. wouldn't it reduce it because you are removing a spacer on that shaft and by doing so you effectively will allow the fork to extend further into the negative air?

How often should forks be serviced as I’ve never bothered with it before and mine still feel fine, but yes newly serviced would probably feel very plush and nice

could u make a coil shock service video

Hi there ,Will removing the bumper not make it noisy? Thanks 🙏

The manual said something about some maxima plush fork oil to put in the negative and positive chambers of the airspring. maybe it does not apply to Pike? i own a Lyrik

Can you please. Please. Make a video for manitou m30 airfork. Mine is loosing air. Ill pump 85psi but the next day it only ratains around 20-25psi

I've done this in the past didn't have an issue this time around I'm working on 2019 lyrics 170mm I got the updated 180mm air shaft I removed black spacer (topout) like you recommended. The fork isn't smother reassembled and it's sitting at about the 15% sag setting when I'm not on it 😒 what do you recommend? When I was assembling the lowers b4 I added air after adding the bath oil I fully compressed the fork with the lower bolts installed a few threads burping the air out of the lowers as I compressed it.

this guy is Bob Ross of mountain biking

Does removing the topout spacer really give that much more volume? Going by the drawings in the RS service manuals, the negative chamber looks to be quite big and it also uses the volume of the air shaft itself. Removing a tiny spacer doesn't seem like it would make that big of a difference when the negative chamber is already massive.

Wondering about the bit where you remove the top out bumper. I know my Luftkappe does not have one and never had any issues ... but not so sure about a stock standard airspring ... please give us more details on this removal ?

Hey Henry or Doddy, how does one lower the travel of a rockshox boxxer rc, ive looked everywhere and all ive found was someone saying to cut the spring and add a spacer to make up the difference but idk how I feel about cutting the spring, its a 2015 boxxer if that helps. I knows its possible because specialized did it with the specialized enduro evo expert to 180mm for the 2015 model, just dont know how, is there a shorter spring that can be purchased? Before you ask why I want to shorten the travel because its an extra fork I have just sitting in the garage and want to use it on a mondraker dune xr haha 🤓

hello, why now in extension you feel a knock as if it reached the end of the stroke. are there any shims to remove? thank you

This is sa great idea. See as youhave the time now.

You Missed cleaning out all the old grease from inside the stanchion, and clean with isopropyl, and then lightly regreasing 15cm around inside again. Key, certainly on RS. That tiny bit on the seal head is insufficient, will lead to binding later...make the fork worse after a few rides. Really need to be careful what gmbn recommends different to manufacturer stated steps, as will lead to problems for your average joe giving it a go. + Exposes psn.

Really good tip with the bottom out bumper, will try that. Sometimes the shafts get stuck when pulling on the sliders when doing a lower leg service. If the damper shaft get stuck and you pull on it too hard, over extending it it, can the damper get damaged?

Hi Henry, I didn't explain it very well at all. I bought a second hand bike and it had obviously been neglected. I had to service everything on the bike. The bike came with Lyric RC2's. I thought I'd dislodged both shafts from the base of the slider legs. The damper shaft must have been still attached to the base of the slider though, I did manage to get the sliders quite far down before I realised this. After your comment about pulling apart the damper and causing serious damage, I wondered if it was possible to damage them by just pulling too hard on the damper shaft. having said all this the forks work ok :)

This may seem like a stupid question but does the rod for the air spring need to be greased of does It get lubricated by the lower leg oil? Thank you

how about putting some loctite on that valve instead of lube just to be sure therse no air leak?

#GMBNtech if there any chance? The damper shaft got scratch is the fork skill safe to use or we have to replace the whole fork?

There's no way that a blob of grease is going to withstand the air pressure trying to migrate through the equalisation port. It's a total myth that frequently mention on all the forums. I didn't expect to hear it mentioned here too. Sucking down occurs due to either a worn piston seal, or incorrect assembly/inflation.

Can you remove that spacer on the upgraded version

Had a hard time trying to put the c clip back in its place tho...

Is this normally done while fork is still installed on the bike?

Great vid - can you do one on replacing / upgrading the damper ? Also, thought had seen that you are supposed to clean / re-grease the inside of the fork tube ?

@Henry Quinney cleaning and lightly regreasing inside stanchion is pretty vital sorry henry. Least on RS. The grease can get dirty, u cant properly inspect inside without thorough clean, and then a tiny bit on the seal head will spread so thin that it will be ineffective. Also, pulling the spring out dorsnt clean the grease out at all...the grease sits above it. Have to say, not doing this part as per sram service steps risks dry seal head and problems down the road. Nit to mention, orientation of the circlip. The most vital part. It ur have smooth edge down, they can pull out, even if seated well. Think an edit to add that bit is vital...has potential for fork fubar and maybe crashes as a result...unlikely, but possible. Sorry to not be my usual H fan self...but agree with poster...key (on RS) elements missing. Will post separately re the top out bumper...major no no on new RS airsprings...too much neg then

Follow the manufacturer steps for ur fork. E.g. the 2020 onwards pike/lyrik etc use a special new fluid, not grease. But mixing these to older forks will cause seal problems. H missed this key point...the new new RS dont use grease like that...will ruin the fork Sram website has all service vids

Now I can't unsee that ....

I cannot see how removing the bumper increases (!) the volume of the air chamber!? The length of the chamber shrinks by the height of the bumper which will affect the chambers volume, too. Second, Iam guessing it will increase travel as more of the airshaft is exposed out of the stanchion towards the bottom of the fork.

@gmbntech

4 жыл бұрын

If you made this bumper larger it would reduce the volume of this chamber (just as the plastic volume spacers do in the positive air spring). Removing the bumper allows for the maximum amount of volume available. Don't worry the shaft remains the same length so travel won't be affected.

Great bike , rides smooth kzread.infoUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L I added a bigger spring loaded seat to it . Takes a bit of adjusting cables to get brakes and shifting to perfect . I've owned quite a few bikes in the past that were absolutely uncomfortable to ride and they always ended up as garage wall decor . I'm not seeing that with this one. It's pretty light I've only ridden it a few miles but I like it . As for the pedals falling off in the other reviews , the pedal arms are aluminum along with the pedal studs look to be also . I would not overtighten them. I can see it would be very easy to overtighten them and strip the threads right off . All in all I think it's pretty good quality besides the aluminum pedal thing

Not sure I can take Henry seriously with that nose ring.
