Hi guys

 

I found the O-rings leaking on my 2015 reverb dropper lever as the dropper no longer raises and the handlebar was full of oil. This happened about 4 months after the post was serviced but I noted in the bag containing all the old seals that they did not contain all the lever piston, speed adjuster and hose O rings.

Can one purchase these orings separately?

I have measured them all so could possibly source new but prefer to get OEM.

 

Any suggestions who may stock these seals.

Came to the same conclusion just last night - replace seals.

 

Should be able to purchase them from a seal supplier your bearing man should also have them as they are pretty standard.

I remember when I got the dropper back from service the speed control was not operating properly and it seems that O-ring is a bit tired as well as the piston o-ring an there was a fair bit of moisture in the lever.

The piston o-ring has a nylon backing ring.

The sizes I measured

Hose saddle end 4.2x1.5

Hose lever end 4.5x1.5

Filler plug 4x1

Piston 4.2x2

Speed control 9.4x1.5

Drop me a PM if you need a hand, I'm in CT.

 

If your lever is shot, not just seals, I also have a spare in my box.

Thanks. I have bought the orings already.

 

All I need is a bleed kit which I haven't yet found.

Have a complete spare dropper post and lever from a mate of mine that got diddled by a guy on gumtree that sold him a dud and he wasn't prepared to pay for it's service and repairs so I scored it for parts.
