Grand Cru Sealed Bearing Universal Jockey Wheels
VO Grand Cru derailleur jockey wheels are made from a special Swiss nylon that we believe is superior to that found in most other jockey wheels. They use sealed cartridge bearings and - this is the best part - they come with a set of shims that will allow them to fit most modern or classic derailleurs that use 11-tooth wheels. They will also work with some derailleurs that came with 10-tooth wheels, but check that there is room for 42mm diameter wheels. Per pair.
