The Chorus 11-Speed Cassette is Campagnolo’s most durable 11-speed cassette. Nickel-chrome coated steel sprockets are 180% more rigid and 70% more resistant to torsion for fast and fluid shifting action. Each sprocket tooth is designed for maximum synchronization, shifting speed, and silent operation. The six larger sprockets have a double frame system for extreme torsional stiffness, so that operating precision is maintained even when shifting under stress. The surface treatment of the 11 steel sprockets assures longer component life and maximum performance over time.

• Ultra-Shift Teeth Design means every sprocket tooth is designed and placed to perform a specific function, such as raising or lowering the chain or giving maximum power transmission to the wheel
• Ultra-Shift Synchronization sprocket tuning allows for maximum shifting performance without hesitation — it’s fast, accurate and quiet, even under stress
• Reinforced mounts for second and third triplets offer greater sprocket set rigidity, performance and precision
• Steel construction with nickel-chrome surface treatment reduces chain/sprocket friction and extends sprocket life
• Light alloy lockring for weight savings
