    Lefty Sometimes Seems to Lose All Air Pressure but otherwise fine

    I have a 90mm travel Lefty PBR (2011) about 100PSI in there. Sometimes I'll stop and maybe lean on the handlebars and the Lefty will just lower very slowly...all the way through the travel, so it's bottomed out and sat there. If I then take my weight off it, it'll come back up and after that behave as normal. (ie: seemingly functioning perfectly)

    I've never had this happen whilst riding and it doesn't seem to be a problem but I wondered if this is normal and what is actually going on to cause it?

    thanks for any advice.

    Not normal. Looks like some air sneaks out of where it should stay. Bad seal? Something not tightened correctly? I'll let the internal experts get more precise on the cause (there was a thread on the same issue a while back).
