My Reverb has suddenly started to go both up and down slowly. The only thing that could have caused a difference is me flying over the bars and the bike having a good bounce around after which the seat no longer pointed forward. I loosened clamp and re-aligned it but am wondering if this has caused the problem. I have tried slackening off the clamp completely and this makes no difference to Reverb speed.
How to return it to its previous rapid movement?

check the pressure. They try a bleed.

Clamp too tight?

Clamp too tight?

Could be this. Dropper posts can be quite susceptible to being clamped too tight.

IIRC the Reverb has a max torque setting of 6.7nM
EDIT – Ignore that, I missed the bit about undoing the clamp. 😳
Try a bleed first.

has the speed adjust twiddleyknob been moved?

Still does it with clamp completely slack

Re bleed

What M1llhouse said….could be something simple like that.
