This Campagnolo Chorus 11 cassette has been designed to optimize the speed and fluidity of shifting. Its innovative machining reduces stress on the chain, allowing it to ascend more easily onto the higher diameter sprockets. The larger cogs are divided into sets of three and are mounted on a new carrier, increasing the rigidity up to 180%, and individual sprockets are 70% more resistant to torsion. The steel sprockets have a Nickel-Chrome surface treatment for durability. You'll love the solid, precision shifting offered by the new Campagnolo 11-speed rear sprockets.
