Campy's New Chorus 12-Speed Group Benefits from Trickle-Down Technology
The new Campagnolo Chorus 12-speed Cassette has been designed to optimize fast and crisp shifting. Its innovative machining reduces stress on the chain, allowing it to ascend more easily onto the higher diameter sprockets. In addition to 11-29t and 11-32t options, the new generation of Chorus introduces a new cassette specification of 11-34t, providing cyclists with a larger gear range for more efficient climbing.
The larger cogs on the new Chorus cassettes are divided into sets of three, 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 12-speed rear sprockets.
