If it’s not the bearings, check that the silver bit of the pedal body isn’t separating from the black bit. It is a known warranty issue with vector 3 and I just had a pair replaced.
I was eagerly following this too, along with the cranks. I guess it’s the nicest 11 speed silver campag group. The new 4 arm cranks are ugly and are powertorque, and the levers don’t have ultrashift.
Anyone?
