Is my rear shock too soft?

[Mububban]

I'm new to air suspension and dual sus bikes. On my only trail ride (so far) the O ring on my forks (150mm) seemed to indicate a good use of travel, but not bottoming out. However the O ring on my rear shock (140mm) seems to be right down near the bottom of the stanchion (?).

These pictures are after riding up on the street, hopping kerbs, bouncing on the pedals, and riding over a home made ramp:





I'm maybe 70-72kg fully loaded for riding. 66kg in the buff The bike shop set my initial air pressures, sag and rebound etc. 110psi in the rear and 75psi in the front. The bike doesn't feel bad, or harsh, or too soggy either, but then again, I don't know what I don't know...

Do air shocks leak air pressure over time like tyres do, or are they pretty much "set and forget" once they're dialled in?

Doesn't look too bad... is there a preload knob still with air shocks?

Afaik air pressure will leak out eventually, there's no such thing as a perfect seal.

Looks like a bit much travel used unless you’ve taken a fairly big hit. Def worth checkig the current pressure.

I think you will find the o-ring for the rear will work its way down very quickly regardless of true travel used.
You should be checking it after a static sag test not after riding.

Same with the front, but obviously the front o-ring is not going to work its way up without help from travel use. Doesn't have gravity on its side
