hello, am new to MB'ing. Have real nice Commencal Combi S MB soft tail w/ Bar R shock. It just doesn't hold air long, but intermittently does- so I'm thinking it's not "bad" but I'm doing something wrong. I notice it holds air longer if the 'rebound' knob is seated CW. If I attempt to adjust after its filled it seems to leak rather quick. When pumping it up it seems to respond and extend quicker if the 'rebound' knob is a little CCW. then tightened up, but this seems weird as it shouldn't make a difference? Any advice is appreciated. Incidentally the bike itself it the best bike I've every owned.

Thanks...

Reply to own post.... I squirted a little light oil in there, after removing the valve core, of course. It seems much better, This next week will really tell.

That may be all that was needed. Not so much the oil, but the valve core removal and re-install. May have been a bit loose, and snugging it up may have solved the leak. So long as you didn't put in more than a couple mls of oil, that shouldn't cause any trouble, though it may cause the shock to ramp up into it's travel a bit more. Dump all the air out to ensure you've not added so much as to impede the shock stroke.

As for the rebound knob? No idea.

thanks scrublover... I've put only about 30 miles of commuting type up and down on it, and it sure is holding air. thanks for your input.
