Are the older silver hollowgram Si cranks compatible with the newer BB30a standard ?
Seems like I just need a 109mm spindle and appropriate spacers/washers etc... is that right ?
I’d prefer to have a set of silver ones rather than the newer black ones.
Thanks !
Cannondale Hollowgram / BB30a compatibility
The 'pitch' of the non-drive side crank arms needs to be different to maintain the same Q-factor when changing axle length, a BB30A and BB30 non-drive side crank arm are different. So if you take a BB30 crankset and use with a BB30A axle the Q-factor will be different on the non-drive side as the pedal will effectively move further away from the centre line of the bike.
