My Rock Shox Revelation is bottoming out after traveling approximately 30mm when it is set at full travel. If I crank it down to where is should have about 100mm of travel, it is essentially locked out, and only travels 5mm tops. I've checked and double checked air pressures and the lockout dial. This is my first air spring shock, so I'm quite inexperienced with the newer equipment. Does anybody have any insight or am I best to take it in to my LBS and have them rip it apart?
