Is anyone out there using an SRM Origin PM with a 24mm BB axle? I'm wondering how it is with the reducer shim that takes the NDS crank fitting from a 30mm to 24mm axle. Are there any issues with creaking or movement or anything I wouldn't appreciate? And how robust is the pinch bolt setup and extraction method on the SRM composite (not the Look Tri-Lobe) crank?

I currently have a DA9000 SRM PM that has been rock solid and bombproof and I don't want to add any hassles for myself.

Thanks.

Had no issues with my 24mm version of the Origin.

Two BB90 bikes with Origin and 24mm reducer. No problems ever. Please pay attention on "slit on slit" between crankarm and reducer.

Have cracked a few of the reducers which lead to creaking. Seems to be a new aluminium design now instead of plastic and no issues since.
