The Campagnolo Chorus 12-speed cassette delivers smooth, reliable shifting and outstanding versatility, designed to work seamlessly with both disc and rim brake Chorus groupsets. Fully compatible with Record and Super Record 12-speed systems, it provides a flexible gearing solution for a wide range of riding styles and terrains.
With the introduction of the 11–34 option, riders benefit from an expanded gear range, making steep climbs more manageable while maintaining tight gear steps for efficient cadence on flat terrain. Whether racing, training, or tackling varied routes, the Chorus cassette adapts to your needs.
Engineered with precision, the cassette features single-block steel sprocket groupings to maximise stiffness and minimise energy loss. Advanced surface treatments improve durability and ensure long-lasting smooth performance, while consistent spacer thickness simplifies installation and guarantees accurate setup.
Maintaining the same width as an 11-speed cassette, it integrates easily with existing wheels and frames, making it an ideal upgrade to modern 12-speed performance without additional compatibility concerns.
