I receive an answer from a webstore for BB Rotor:

For Shimano cranks (24mm axle diameter) the following BB would be your choice:
- Rotor PressFit 4624 BBright Steel Bottom Bracket (item code: ROT134528)

For Sram BB30 cranks (30mm axle diameter) you can choose between the following BBs:
- Rotor Press Fit 4630 Road Steel Bottom Bracket (item code: ROT134525)
- Rotor Press Fit 4630 Road Ceramic Bottom Bracket (item code: ROT134526)


Than now, it is possible to place a BB30 crankset on a Bbright Cervelo frameset :thumbup:

If you mange to put it on, don't forget to let us know :wink:
I would strongly urge you to read carefully what Sram 30mm spindle crank you can use with bbright.
I can also refer you to:
http://www.bbright.net/" and Cervelo forum.

IF you do, in fact, try to install a Red crank WITH INTEGRATED SPIDER onto a bbright frame, i'll be here to say I told you so.

And anybody use this model :

FSA BBright Adaptor Bearingcups for MegaExo Road Carbon Cranksets

Is this ok for Shimano crankset?

You will likely need a 1mm spacer between the bearings and the arms on one or both sides. Otherwise, your shimano preload cap will bottom out early. Other than that, it fits.

For the one you mentioned- FSA bbright adapter for carbon megaexo road cranksets.
If you find their adapter for ALUMINUM megaexo road cranksets, you will not need any 1mm spacers.
