Campagnolo Chorus cassette

The Campagnolo Chorus 11-speed cassette is also used in the Athena and Veloce groupsets.

Optimised tooth profile with a treatment that extends service life. The tooth profile of the Campagnolo Chorus cassette improves the speed and smoothness of gear changes. This tooth shape reduces the stress on the chain, allowing it to move up to the larger chainrings more quickly. The larger sprockets are grouped in sets of three and mounted on an aluminium carrier frame. This increases stiffness, and the individual sprockets are 70 per cent more resistant to torsion.
