Are the SID inner fork legs identical? I have the Rock Shox Sid Carbon World Cup. The manual as well as decals on the fork show the left hand leg to be the postive and negative spring air chambers and the right leg to be some other air adjustment (damping?) but the air valves are not. (left and right from drivers positon) So I am thinking they have been assembled back to front? Hence the question. Anyone know if it is an easy job to take apart and reassemble? Anyone know about the "SID threaded base retainer tool" that is needed to remove the dual air assembly?
