Hi there folks, just putting a question out there for any knowledgeable peeps regarding rear shock on my codeine. Got cane creek db air which was great till the damping blew up, so returned to tf tuned for warranty repair, however before and after repair I seem to be hearing a knocking noise from rear over really rough fast terrain, Ive checked bushings and they are nice and tight (it sounds like loose bushings) could it be an issue with the shock, thanks in advance.
