Hi All
Advice please...I was wondering is there a real diffence by upgrading the cartridge bearings on my wheelset (Mavic cosmic carbone sl) to ceramic?
Also can anybody advice on what bearings it would take size/model. From what i can tell these are the model numbers but other sources give diffent results:
Hub: 1 x 61903
Rear Wheel: 2 x 608
Front Wheel: 2 x 61901
thanks
