My rear hub cracked a flange at a non-drive side spoke hole. The Campy website doesn't give a part number for the flange assembly (everything else, though). I'm probably missing something. Any suggestions on where to purchase (1) just the flange assembly or (2) a complete rear hub. I'd like to rebuild the rear as as a backup wheel.

I replaced the Vento's (32,000+) with Fulcrum 5's, sweet wheel, but would like to rebuild the rear if possible.

Thanks,

Bill
