I recently got a set of mavic wheels with campy hubs/cassette on them. I am going to rebuild the rear wheel for my fixie, and I'm trying to decide whether to keep or sell the rear hub. Since I am not usually able to afford Campagnolo parts, I know nothing about how to identify them. They look to be newer (not vintage) and they do not say the gruppo name anywhere on them. Could anyone help point me in the right direction to indentify these? Also, since I am a "newbie" here, does anyone know of someone on these forums who would be able to identify them at first sight? Thank you.
