Got a Canyon Ultimate CF-SL in the workshop that needs replacement bearings in the headset, the lower "crown race" bearing was very rusty and fell apart when I removed the forks with the upper section of this bearing still rusted and stuck inside, best measurement I can get is 48mm x 40mm.....question is does anyone know the correct replacement lower bearing size as the old one is in bits? any help/guidance gratefully received cheers Griff
