Can anybody tell me please if a SRAM Red BB30 crankset will fit straight onto my SRAM equipped 6.9 Madone with BB90 bottom bracket?

Considering buying a Quark power meter but need to figure this out to prevent a potentially expensive error.

Thanks

The BB90 is high-end technology manufactured by TREK. It also has the advantage of being compatible with any chainset, giving you a great choice.

No, a BB30 crank will not fit a trek BB90
It's about the only combination that's not possible by any means.

The baboon is right. Can't be done, bearings are too small.

Well... It is physically possible by running two bearings each side, but it doesn't actually work.
