I am upgrading my cranks to XX1 from XX. I have a 2012 Superfly 100 pro size medium and need to know hat my current Q factor is so I can order the same in this crankset.
I believe it is the smaller 156 I believe but I am not sure. I have the BB95 internal bearings on the frame.
Any quick help would be great so I can get these ordered.
