Reverb - able to lift saddle

mattjevans

I just got a new Reverb, done the whole fitting, hose cutting, full bleed successfully and its working fine in terms of uppy-downy-ness

If I pull up on the saddle while it's in the down position, however, it will lift up. Upon releasing it, it "sucks" back down again.

I have searched and seen anything from "you have a blown air seal or are about to" to "this is totally normal and mine has done that for ages and works fine".

What's the consensus on this "feature" here? Leave it or send it to SRAM?

I don't have one but it sounds like something you shouldn't need to do. It has a lever mounted on the bars so I've no idea why you'd want to pull the saddle up manually?

I know that's how some posts work. The Joplin 4 always does that.
What I don't know is whether or not the reverb is meant to do that, but it's certainly not unusual.

My reverb will pull up when its in the down position but it takes some force to do so and so I dont do it as it cant be healthy for the hydraulics, it then sucks back down as you describe. If its doing what it should do i.e. stay up and stay down when you want it to I'd just ride it.

No, I don't "need" to do it and its not what I do to actually extend the post upwards.

What I mean is if, for example, I pick the bike up by the saddle, the post doesn't stay locked down but instead has a bit of extension movement. That movement is reversed by itself as soon as the upwards force applied to the saddle is removed

Sorry just read it wrong then! I'd expect that from the hydraulics, so it seems normal.

turns out air pressure was low
