I recently built a new bike around a full suspension frame that's been in storage since it was built in 2007 or 2008.
It came with a shock, but there are no markings or decals to indicate a type, or even a brand.
The shock is losing air at an alarming rate. I had put both chambers at 170psi just before the first test ride, and within minutes the rear chamber lost all pressure.
The front chamber seems to keep some air because it doesn't collapse and is capable of carrying my weight, but after 2-3 minutes of riding it feels all wobbly and mushy even on flat roads.
Because I didn't have a clue as to the correct settings, I had my pump with me and re-inflated the shock a few times. All to no avail though, it kept losing air. I assume that one of the seals is leaking and the shock will need an overhaul.
Before I take it to my LBS, I'd like to know what type of shock this is so they can order the right parts. I've Googled a bit for RockShox, DT Swiss and Fox shocks of that era, but didn't find anything that matches this one or even comes close to it.
It has dual air chambers and a rebound adjustment knob, but no lockout. Eye-to-eye, I'm measuring 168mm.
The rebound adjustment knob has a dual-sided arrow with "+" and "-" marks, and a "R" on it, but no further identifying marks.
Any pointers as to the brand or the type would be greatly appreciated.
