Replacing Ultegra with FSA Compact Energy
 

Hi,
can I replace this:

with this:

Is this possible? I suppose I need to buy an Isis bottom bracket but which one?

does everything else stay the same (apart from lowering the front derailleur)?

Thanks for your help

As I read it you need an isis 108 spindle BB to go with the FSA crank. Threading obviously has to match your frame threading.

I have a similar question, i am looking at the Vigorelli cranks for my pursuit frame, it has a 36x24 70mm italian bb, I understand that i need ISIS 108 spindle BB, but will this fit into the bb?

Can anyone shed some light, i have explored quite a bit and even read FSA tech articles, still mystery.
