RockShox Reverb Service AKA How to Fix Sagging Reverb Droppers

Oil change on a RockShox Reverb A2 dropper post. I demonstrate how to fix sagging Reverb dropper posts by doing an oil change on them. This post was working fine apart from aeration of the oil. If the post has lost fluid due to worn seals, a more extensive service is required. I can make a video on that if it is of interest to anyone.

Sagging is a very common problem for these posts and is caused by aerated oil most of the time. Aerated oil is mostly caused by pulling up on the seat when the post is retracted, which creates a vacuum and aerates the oil. To avoid this, it is best to always extend the post unless the seat actually needs to be lowered.
The other common issues with these posts is that the post does not react to user input from the actuator. This is caused by air in the actuator hose due to a leaking lever or improper bleed.
