i know ive posted this before but nobody seems to respond . Im desperate here, all i get from shops is "we will send it away". I have a rock shox SID team 2004, it is leaking air on the negative side. First of all, what causes air to leak on the negative side? I assume by looking at the SID service guide it is those 0 ring seals which you can but replacents, SID dual air 0 ring service kit on Alfred E bike. Is this correct? And finally would a bike shop be able to replace these things for me? ANy help at all is appreciated!
