Jan, That quoted weight was less tires, as the tradition was? I bought a carbon fiber Centaur derailler, only to find it was the same wei ght as the all alloy version it replaced. Plus to rub salt into the wound, Campy had cheapened-up the construction of the carbon fiber version. I'm looking forward to getting the latest issue of VBQ. Cheers!
