Campagnolo Chorus Bicycle Cassette (12t) - 11 Speed

Painstaking work was carried out on the sprockets!

The additional speed led Campagnolo to devising a new support structure for the last six sprockets in two subsets.

Key Features:

• Eleven sprockets that are even more efficient; despite the reduction of the thickness.
• The teeth have been designed to optimise the speed and fluidity of shifting.
• This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets.
• The large pinions are divided into sets of three and are mounted on a new aluminium frame.
• Thanks to this rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.
• Nickel-chromed finish.
• Light alloy supports for the final two triplets.
• Light alloy lockring.
• Weight: 236g (Manufacturer claimed).
