Nicholaswrote a review of Campagnolo Chorus 11 Cassette on April 3, 2015
Familiarity: I've used it several times
I have 3 bikes on Campy and 2 on Shimano.
The two on Campy are Record and the one on Chorus. I have to say, this is a heavy cassette (naturally) but if you can handle a little heavier, the cassette is flawless and works just as well as record.
