Just got my SID WC 29 Fork and it came with out the o-ring that goes on the crown. A quick call to Specialized said "go to your local auto parts store or call SRAM". Any suggestions? I am sure Specialized did not make a special o-ring for the carbon crown but they did not the size o-ring needed. I am pretty sure SRAM won't deal with a consumer on this one. A little disappointed they left that part out but at the same time it wasn't ez to get the fork.
