Anybody running oval rings (specifically Rotor OCP3 compact, or Stronglight BioConcept compact) on Sram Exogram BB30? I read the Exogram thread, and it seems like there was some controversy on chainring timing. Any experience/advice is greatly appreciated.

I have Q-rings on my Quarq Else, which is pretty much a de-labeled SRAM Red. 50 aero OCP3 outer and 36 inner

@jooo - You should probably examine the bolt pattern in the picture then reconsider your statement.

It's because I'd looked at this picture in the gallery only a few days ago:

:oops: serves me right for not looking at the picture for more than a second...

So the Biocoencepts will not fit on a Red Exogram BB30 170 50/36 without filing. Does anyone have a basic filing pattern to follow for this procedure?
