Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

But I still need the BB30 BB right?

If you get an axle you should get all the BB parts with it.

If you get an axle but no bearings and whatnot, then any BB30 BB kit (bearings, covers, wave washer, 1mm preload spacers) will work, although you might have to make the larger spacers yourself if you are fitting a 109mm axle to 68mm BB30 bottom bracket shell. Some headset spacers work for this.

Any non-ceramic BB kits out there?

Not sure if Cannondale do a 'non ceramic' kit, but they can be had from SRAM, Token etc but you won't get the cannondale specific parts with them.
