Campagnolo Chours 11 Speed Bicycle Cassette

He is the only difference with the Chorus 11 cassette is this: All 11 cogs are made with nickel-chrome coated steel where the as the Super Record 11 cassette has 6 Ti cogs and the Record 11 cassette has 3 Ti cogs. With the Chorus 11, you get no Ti cogs, which is 56g more than Super Record, and 35g more than Record (Save your money, go with the Chours).
