Shimano 6800 bottom bracket compatability

Postby Phil485 » Wed Dec 25, 2013 14:34 pm

Hi all,

I want to upgrade my 2013 Felt AR5 from an FSA gossamer pro crankset to the new ultegra.

Can anyone reassure me that the bottom bracket will be a direct swop out.
The FSA is it's own 386bb standard and the ultegra is hollowtech 2.

Also I'm assuming the front mech is band on. Is this correct??

Unless your bottom bracket is the hollow tech 2 standard or BSA English threaded type your Ultegra 6800 BB won't work.

You'll need the correct BB386 to Shimano adapter to run an Ultegra crank.

Cheers Major Mantra, had a look at adaptors..
It's a real minefield out there....
Front mech is braze on, again need to do more research on the differences.

All because I want to try out a stages powermeter.!!!
