non stealth version /external routing/ is different. it is necessary to use vise clamps with 10mm hole (i have seen some on aliexpress for 15 euros or so).

Why dont you recomend replace the green seal?

This is a great video - thanks. My ~2018 Reverb Stealth is rarely compressed but has developed a loud creak under pre-loading sag, IE, when sitting on the saddle or every slight unweighting with each pedal stroke. I have not stripped it yet but was wondering if this is a known issue - it is definitely in the Reverb and not in the frame or saddle. Varying the pressure 190-250 psi makes no difference but the creak is much less obvious in colder temperatures, below ~15^C. Other than that, it works as normal, fully locking out at arbitrary heights, with minimal sag (activation is via SRAM Force LH lever, as this is a 1-by setup - Vielo V+1).

this sound is probably from one of two sources: from dirt in bushings/brass keys; from top out plastic ring. you can try to clean bushings without opening oil system - step 2.5 is last step for you while disassembling. usually it is preety easy. if this not helps, probably there is a problem with top out ring. it is inside a part i hold at time 7:55. newer service kits contains this part. older kits contains only inner seal and topout plastic ring, but inner seal is very hard to replace.

@@cassobiker Thanks - I found my problem: My dropper collapsed last Sunday and the culprit was the lower circlip; the OEM part is vulnerable to corrosion and mine had almost completely vanished before bursting through. I only retrieved a tiny fragment. I opted to buy a 3rd party stainless steel replacement and guessed this size (30.9mm OD dropper post): Simplybearings: 1 x Stainless Internal Circlip 29mm Diameter Un-Sprung Dia 31.1mm pack of 2, £6.49 These are probably one size too big: although they fit inside at full circlip plier compression, they have a thickness of 1.1-1.2mm which did not cleanly seat in the undercut, so I flat ground it to 0.9-1.0mm with a Dremel disk and chamfered the upper surface, keeping the working face untouched and sharp. This worked perfectly on tonight's 20 mle test ride - silent, with no creaks!

How does this tutorial differ for an A1 model? Will this video be helpful?

@cassobiker

an A1 model is very simmilar to a2/b1. main difference is an IFP. i strongly recommend to replace old type with new one, because old type IFP makes most problems. you can buy new IFP as a spare part, it is cheap.

Thanks for the video, and the most recent of them all. Thank you for not filling empty space with lame pirate music. I don't know why people make such a fuss about removing the oil. I just use the same syringe I use to bleed the remote, attach a 6.5 inch piece of tube (depending on your model) on the end, drop it in and suck up the oil. A lot easier than some of these other DIY hacks.

Great video, thanks man. I think I need to do mine. I just bled it and also added air to 250psi. It comes up nice and quick but going down, it’s stiff like there’s some kind of friction. Do you know what would cause this?

Could it be that i did something wrong. I'm sure my IFP is set correctly. Around 51mm for my 150 B1.

if dropper goes slow down, probably some seal on poppet valve is broken or scratched. or one hidden seal inside upper tube. try to unpressure seatpost. if you have a lot of oil in air chamber, it is broken seal inside upper tube, if not, you have some problem vith poppet valve
