CAAD9 BB30 shell IS NOT BB30, HELP!
i purchased a 2010 CAAD9 in feb 2010.
i purchased the caad9-6 with the tiagra group so i can start riding and slowly upgrade.
i have upgraded everything up to the crankset, just bought the hollowgram si sl set and noticed that even though the downtube says BB30, the BB shell is still standard sized.
it is standard bb shell size, threaded, and too small to receive the bb30 bearings.
what gives? is this a defect?
aren't all 2010CAAD9's supposed to able accept bb30 parts?
