Replacement rear axle to fit Campagnolo track hubs.
158 mm in length complete with 26 tpi x 10 mm track nuts, cones etc.
Identical to, and completely interchangeable with, Campagnolo.
If you're having problems sourcing the real thing, everything here will more than do.
You could even use it to convert your old threaded Ghibli or Khamsin road disc for use on the track or fixed wheel time trialling (together with one of Harry Walker's 'fixed wheel converters').
Sourced from Italy. Superb quality. In stock and ready to dispatch from PDQ HQ.
