What BB Do I Need
 

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.

I examined the crankset more and found where it says ISIS Drive on it too, I looked online more and some of the BB's that are ISIS have splines out each side, but do not look like they have external bearings. Anyone have ideas???

ISIS bottom brackets are not external bearing designs but very similar to Shimano Octalinks. They have an internal cartridge that is usually threaded into a 68 mm English threaded bottom bracket shell or, more rarely, a 70 mm wide Italian threaded shell. They have splines at both ends of the spindle and the crank arms mate with these splines and are held by threaded bolts.

TH ISIS BB's available here (and elsewhere):
