Will this crank work on my bike? BB30 or GXP?
https://www.specialized.com/us/en/bc/...jsp?spid=56855
It says BB30-"COMPATIBLE", but will it still work with a GXP BB?
The bike in question is a Roubaix SL2 which currently has a Truvativ Powerspline BB and SRAM S150 crankset.
I really appreciate any convincing insight here. Thanks.

That's a good question that I'd like to know too. With all the different BB standards, things get confusing. I'm still using square taper and ISIS BBs and cranks.

With so many different standards, it is simplest to always go for the same standard that you currently have, rather than attempting to get adaptors, just get another crank which will worth with a BB30. All this info will be on the manufactuers websites, just match the part number with what you are looking to do with it.

Question: Is the actual cavity needed for BB30 larger than that for GXP? I've seen adapters that allow a non BB30 crank in a BB30 compatible frame, but not vice versa, which leads me to to believe BB30 is bigger, and the adapters can only make things smaller.

I agree with Reptilezs, it won't work. This is not a BB30 crank. It's a Powerspline crank and will only work with a Powerspline BB. BB30 cranks only work with BB30 bearings which are outboard, you can see the ring on each side of the outside of the housing. A BB30 crank is held on with 2 bolts, 1 on each side of the crank then the other crank is attached to the axle.

Ok, so SRAM Red GXP it is. Thanks guys, would have been easier if Specialized had worded things better in the description.
