Campagnolo Chorus 11spd Cassette 11-27, 11-29.
Every sprocket tooth has been designed to achieve the maximum synchronisation, shifting speed, and silent operation.
The six larger sprockets have a double frame system for extreme 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 the maximum performance through time.
Ultra-Shift sprockets synchronisation: improved shifting precision, less stress for the chain
Ultra-Shift teeth shape: upshift optimisation
Optimized teeth space: longer life, lower wear
Ultra-Shift aluminium frame for last two sprocket triplets: precision and greater stiffness, weight savings
Nickel-chrome surface treatments: longer life, lower wear
Light-alloy lock ring: weight savings
Only compatible with mechanical shifting systems / not compatible with EPS
