Rockshox Reverb Issues

Has any one else tried the "cycling the dropper post whilst the bike is upside down" so called fix to fix sag issues in a Reverb?

Mine was sagging about 15mm a few months ago, but after a service it was alright for a while. Over the last few weeks it has developed a 5-10mm sag (just enough to be annoying more than anything), so i decided to try the cycling it whilst upside down fix that i had seen online.

Well, now the post is about 1000 times worse. It sags about 100mm and wont even stay down at the bottom. I bled the line, but that didn't change anything.

I've decided I've had enough with Reverbs, so i have ordered a Fox transfer. I will see what Canyon say in regards to warranty, but am not too fussed whether it gets replaced or not.

Cycling it whilst upsidedown noooooo. Once it's sagging - service time. Bleeding the line will do nothing. It's got a u-cup seal in there to allow slippery action, but sometimes air gets sucked past it. Yes, terrible post compared to others and I don't recommend anyone spending their hard earned on one*

*unless you have all the tools, parts and time for servicing then the thing will literally last forever*

As above except forget it even if you gave the tools.

My reverb developed 10mm sag after a couple of years use. On disassembly it was clear that air and oil were mixing. This causes sag.

Did the service myself - after quote from LBS which was more than the value of the post. Post like new.

It is all doable but is a massive commitment of time. You also need specialist tools. Would definitely be easier the second time having learned a few quirks and from my mistakes.

These posts are more complex than suspension or brakes but have some similar processes, others are unique.

There are some great guides online including some which show work arounds for not having proprietary tools.

Have since gone to a one up post on a new bike. Other than solid reviews, ability to get more travel and great price an appealing feature is that you just purchase a new cartridge and throw out the old one. Not much more than a RS service kit

First ride with the Transfer ans all good so far. We will see how it holds up long term. Can't be worse than the Reverb.

I guess for the average punter the reverb is above their servicing skill set.
I do my own suspension etc, years of doing moto stuff. Just did my X2 shock.
I actually found the reverb easy enough to do, just a bit time consuming the first time.
I've serviced a few other posts, KS, Specialized, Giant, X Fusion.... for all the negative crap the reverb gets they are actually built a bit better than most, just the added complexity makes them unservicable to most people and more complexity means more things to go wrong.
There are many now that do the job for a lot less money, but when they fuck up, get a new one. Those brand x things seem well priced. Not had one apart yet though.
I have 2 reverbs and they have served me well but if I buy a new post it may be time to try something else.

Lately I have seen more non reverbs with warranty claims, which wasn't the case a couple of years ago, but this is probably due to manufacturers speccing cheaper posts on their oem builds these days.

I Had @c3024446 above rebuild and perform magic on my sagging reverb for a $100 with return postage and it has been performing flawlessly ever since. It feels more solid than it ever did.
To my mind money well spent. Better than throwing it away.
I wouldn’t buy another Reverb and have since bought a KS lev and One Up but if you have an old sagging one and c302 still services them I’d consider it.

The quick & free fix for sagging Reverbs which worked on my wifes bike with the old style Reverb was to turn the bike upside down with the post raised, push the post all the way down while the bike is inverted wait a minute then turn the bike the correct way up and raise the post. Doing this a couple of times fixed about 20mm of sag that has not returned since so it's worth a try before binning or rebuilding your post as it only takes a few minutes.
I too would not buy another Reverb though and I have been using a One up dropper on my own bike which has been faultless.
