Every sprocket tooth has been designed to achieve the maximum synchronization, 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.
Material: steel (nickel - chrome plated)
Gradation: 11-23t, 11-25t, 11-27t, 11-29t, 12-25t, 12-27t, 12-29t
Note from the manufacturer: The 11-29t cassette is not compatible with Campagnolo EPS groupsets.
- Ultra-Shift™ Tooth Design: every sprocket tooth is designed and placed to perform a specific function, such as raising or lowering the chain or giving maximum power transmission to the wheel.
- reinforced mounts for second and third triplets: greater cassette rigidity, performance, and precision
- Ultra-Shift™ Synchronization: sprocket tuning allows for maximum shifting performance without hesitation: fast, accurate, and quiet, even under stress.
11 cogs that besides there reduced thickness are more efficient? Campagnolo made it happen: The shape of the teeth optimizes the speed and smoothness of shifting. The tooth shape also helps the chain jump up to the large chainring. The largest cogs are attached to a newly developed aluminium spider. The stiffness has been increased by 180 % and the single cogs are 70 % more stiff.
