Campagnolo Chorus 11-Speed Cassette

Campagnolo has given their Chorus 11-speed cassette a complete makeover, resulting in superior efficiency, stiffness, and durability. The sprockets have been redesigned to be thinner, which reduces friction and allows the chain to run more smoothly, while the ramps and pin placement have also been reworked for crisper, more precise shifting. The new design reduces stress on the chain, making it easier to move onto the larger sprockets. The large pinions are mounted on a new aluminum frame, which increases rigidity by 180% and makes the individual sprockets 70% more resistant to torsion. The cassette is finished with a sleek nickel-chrome finish, and the final two triplets are supported by light alloy. The lightweight alloy lockring completes the package, bringing the weight of this high-performance cassette to a mere 236g.
