    PF30 Stages in BB90 frame?

    I have a Niner BSB9 (PF30) and considering a Trek Boone (BB90). Is there either an adapter to run this or a replacement spindle for my crank to make this work? I'm running a CX1 crankset with a Stages power meter, which has a custom Stages spindle. Maybe there's a different spindle replacement? I just want to avoid buying a whole new power meter in order to get a different frame.

    'brifter' is a lame word.

    Trek frames use the 'standard' axle size from the 3 big manufacturers...Shimano, the GXP from SRAM and Campy. They are all based on a 24mm axle, nothing larger (BB30) will fit. The frame is 90mm wide, if you do the math that's a standard English bottom bracket (68mm) + 2 11mm wide bearing cups that the threaded bottom bracket of old uses.
