Can you tell me if the Bottom bracket on a 2004 r1000 triple is the same as a 2006 r1000 caad8 ? I have a 2004 triple r1000 ultegra 9 and a 2006 r1000 caad8 ultegra double 10, I want to swap the entire drive train between the 2, ending with the 10 speed ultegra on the 2004.

Next question, am I better off building back up the caad8 with the 9spd of just parting it all out on the bay?

Reason for doing this, the caad8 is a 56 with 10sd ultegra very low miles, the caad7 is a 52 and fits me perfect.

They should all be BSA threaded unless they are marked Si or BB30. More than likely though there all BSA threaded.

Thx, the caad7 looks standard to me, the caad8 has a different
Looking set up, there are large end caps between
The bracket and crank arm? What does BB30
Look like? I don't think the caad8 has it, it's not
Marked anywere .

more than likely the caad8 has a hollowtech bb and the caad7 has an octalink bb. There both BSA threaded so you can swap the cranksets and bb between the frames
