I currently have a 2008 Scott CR1 Pro with a FSA Carbon Pro Team Issue crankset, I current BB has internal bearings which I believe is a BB86. I am stripping this bike to transfer everything to a new titanium frame which has a 68 english BB. I know I need an external bearing BB but I do not know which one for sure, I looked at the FSA site and still was not sure which BB to purchase, any help appreciated.
