Can somebody enlighten me as to the mysteries of BB30?
I ride a Cannondale RZ120 2, 2011, which was advertised as a BB30 bb. Now the frame has BB30 decals on it, but it came with a set of Deore cranks and a Hollowtech External BB.
I recently purchased a set of X0 BB30 cranks, which didn’t fit my old bb. I have since sent them back, and will be running a Hope bb with X0 GXP cranks, with the little converter thingies. My Hope bb screws into the frame fine, but the diameter of the frame is bigger than the diameter of the Hope washers on the bb, so a ring of shiny Aluminium is visible – is this an issue?
What BB did I need to run these X0 BB30 cranks?
Clear as mud???????
