This is a Campagnolo Proton rear wheel with a 10 speed 12 to 25 Chorus Cassette and Campagnolo Proton hub. The rim is in good shape with some brake marks just below the brake track. The Cassette is in very good condition showing light wear. The wheel is round and true with no hops. Also included is the plastic spline that holds the cassette together when it is not on the freewheel, the cassette tool for Campagnolo cassettes and a KMC 10 speed chain. The hub was serviced at my LBS because, well, it was too complicated for me. I admit it. LOL Spins smooth. The tire and tube where some old ones I had laying around. The tire has a bit of life left in it.
I purchased this wheel used at a great price to use on my Schwinn Circuit in friction. I was hoping the extra 3 gears would make a difference in my abilities. The wheel and cassette worked great. My Superbe Pro chain rings did not like the 10 speed chain. Made a lot of noise and grinding when shifting chain rings. So I am not going to change crank sets to use this wheel. I am not looking to get rich off the wheel. I just want to get the money I invested back. The cassettes go for $75 on ebay. Asking price $90 shipped in the CONUS
