well biked

Btw, you've now entered the dark, mostly uncharted world of newfangled bottom brackets with your Shimano pressfit bb. My newest bike is equipped with PressFit 30 bb bearings (essentially nylon encased bb30 bearings that require a slightly larger size bore in the frame than bb30), Ultegra 6700 cranks, and Wheels Mfg adapters (they shim the 30mm spindle hole in the bearings to fit the 24mm Shimano crank spindle).
