I putting together my new bike and I discovered the front brake nut is too short to fit through my carbon fiber fork. I have Campy Record brakes. I looked in the specs and found out that Campy makes a longer nut. The part number is BR-RE427. Can anyone tell me where I can get one? For now I bought a longer one but it's a cheap steel one. I would like to get an original Campy titanium one.
