BB30 / Rotor crankset compatibility

Morning all

I appreciate this is a very noddy question, but, could you please let me know what equipment I would need in order to be able to use my Rotor 3D+ chainset with a Power2Max PM across my three bikes with the following BBs? I

1. SRAM BB30 with - presume nothing special needed
2. FSA BB30 w/ 24mm spindle reducers - no idea what this means - can I take off the reducers and therefore it's a BB30 as above
3. Shimano Hollowtech-II - presume I need to buy one of these: http://www.sigmasport.co.uk/item/Rotor/ ... /10QE?wmp=?

bought the chainset on a bit of a whim from a friend of a friend's dog's friend's friend and now realise that there's probably some more admin to this than I had thought. Cue doing some reading on swapping chainsets and BBs...

Any help much appreciated!

1. May need spacer as crank is wider than standard BB30.
2. Remove adaptor, then May need spacer as above.
3. Hollow tech too small so replace BB with Rotar 30mm BB as you suggested.

Agree with above:
1. Rotor 3D uses longer spindle that conventional BB30 - expect Rotor make some sort of adaptor/convertor
2. Correct - remove spacers, as above
3. Remove Hollowtech BB and fit Rotor BSA30 BB
