Reverb fault

At the end of a ride, just as I was within sight of the car, my saddle would not descend all the way. Instead, it stuck half way down and only slowly returned. Once off the bike, I leaned on it a few times to explore the problem. It feels as though it is binding mid way down the stanchion. With enough pressure, it will go down all the way, but is tight at the mid point, before slowly coming up, sticking briefly at the mid point.
Has anyone had this failure mode before and know whether it is terminal or recoverable with a service?
My usual failure mode with Reverbs is the saddle drops a few mm and then slowly gets worse. This is a new one!
The seatpost collar is not too tight, in fact I also use Finish Line assembly gel to allow a lower torque setting on the clamp bolt. Over tight clamp bolts are a common cause of Reverb failure, as it compresses the delicate internals. The stanchion is not scratched or scored and the dropper stanchion and wiper seal have been cleaned and lubed before every ride. The Reverb is one month outside its two-year warranty! (typical!)

Steve - I've no idea what it is but could it be a sticky remote that needs a bleed?
Plan B is send it to these guys for a service:
https://www.ebay.co.uk/itm/ROCKSHOX-REV ... :rk:1:pf:0
They brought mine back to life."Ride, crash, replace"0 -
I took the bike to Dale at Sherwood Pines Cycles. He took the bike home, fixed it overnight and brought it back the next day, all for £60 including labour and vat. I was expecting to be told it was either scrap or not worth fixing!
The problem was that the post was "full of gunk". The fix was a good clean up and the application of a 50-hour service kit. The Reverb now has a fresh seal, bush, guides and has been bled.
When I asked what the "gunk" was I was told it was "oily dirt" and I was advised to have a lower service every six months to keep the dropper running sweet. The dropper has had zero maintenance since new (2 years 1 month), apart from wiping and lubing the stanchion before every ride. Maybe that was where the oily dirt came from? :oops:
What an excellent service that was from Dale at Sherwood Pines Cycles. Not only did I not miss a single day's riding, but there were no postage charges that I would have incurred if I had sent the post off to a specialist.

Glad you sorted it. For £60 you can't go wrong.
Just to offer an alternative - the link I put up for the eBay option was £39. It cost me £5 to send the Reverb back, they got it the next day, fixed it and sent it back on the same day. I received it the next day and was without it for effectively 72 hours.
The cost of return postage was also included, so £44 all in. I know I had to post it etc but it's still good value if you don't have a LBS close by. I've had good service from Pines before when they respoked an e13 wheel."Ride, crash, replace"0 -
I was hesitant about using eBay for something like that, plus the delay, plus the faff removing and refitting the stealth Reverb, bleeding the hose etc. I've done it so I know how much of a faff it can be.
Super glad it worked out for you.
