What the heck do these numbers mean: Q908289 600000/blk B1-0302. I think my bike was built in 2005 and its black but besides that???? My crankset went belly-up. The threads for my right pedal broke loose from the crank arm. Pedal still can be mounted but is very loose. Local bike shop said it can't be fixed. They want $500 for a new carbon crankset! Trying to find alternatives. like a used crankset. Any help out there?
