The post was slow after a few weeks of riding. I turned the screw to the fastest setting. The post locked up and wouldn’t move at all.

Took it in to the shop, they bled it, and it was fast again. They said sometimes an air bubble forms in the cable. One week later and it’s stuck again.

(I’m not lifting the bike by the post.)

Any ideas? Thanks!
 
It seems that one bleed is never enough for a Reverb, they much prefer a course of daily bleeds spread over a few days. If that doesn't work then it's probably time to give the post a proper service.

One thing you might notice if you look at any air bubbles in the Reverb bleeding syringe is that they're going nowhere in a hurry, they're very content to just hang about in the fluid. This is not conducive to a good bleed, and is probably why it takes two or more well-spaced attempts to get the worst of the air out as any remaining post-bleed bubbles need to slowly drift up to an area where they can be bled out on the next attempt.

The remote actuators also need servicing (or replacing) periodically as worn seals and pistons here will introduce air into the line.

I've found that cold weather brings on issues with my Reverb if it needs a bleed or a full service. I've wondered if a partial service (just a post fluid change, without replacing seals and IFP) would also cure most sticky issues, but I've never had the nerve to try this as the thought of having to strip the thing down twice fills me with horror.
