I am planning to build up my own bike - however bottom brackets compatibility is very confusing,in particular bb 30 pressfit and the bbright bb30 - I can get a standard Sram force crank - GXP - in a groupset fairly cheaply but how would you adapt this crank into the above bottom brackets?

    it depends on which one you have.

    there are a few different BB30 to BSA adaptors.

    a threaded sleeve.
    reducers to fit the BB30 bearings
    and a self threaded BB.

    back to you for more info.
