Upgrading chainset

specialized_nick

Hi all,

Apologies if this is a stupid question but I have very limited mechanical knowledge :oops:
Planning to upgrade my Cervelo R2 chainset from the stock FSA Gossamer BBright to Dura Ace 9000.
Both 11 speed but will I need a diferent BB or are they compatible?

thanks!

Not directly compatible. The BBright is designed for cranksets with a 30mm spindle whereas your Dura Ace crankset will have a 24mm spindle consistent with all the Shimano HT2 kit.

There are adapters available such as

but you may be able to source a cheaper option than the Wheels Manufacturing one
