Campagnolo Chorus 11 Speed Cassette 12-25

Campagnolo Chorus 11 Speed Cassette 12-25 The 11-speed Chrous Cassette works in harmony with the Campagnolo Chorus drivetrain as it calls upon new levels of precision that its engineers have delivered. Every sprocket tooth has been designed to achieve maximum synchronization, shifting speed and silent operation. The six larger sprockets feature an alloy 'sub-carrier system' for improved torsional stiffness so that operating precision is maintained even during shifting under stress. The surface treatment of the eleven steel sprockets assures longer component life maintaining maximum performance as the miles rack up.
