Chorus 11X Cassettes

**Warning: EPS Groupsets will not work with 11/29 ratio cassettes. Use 12/29 instead.** Every sprocket tooth has been designed to achieve the 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 during shifting under stress. The surface treatment of the 11 steel sprockets assures longer component life, maintaining the maximum long term performance. Technical Specifications: * Steel * Nickel-chromed finish * Light alloy supports for the final two triplets * 11x Spacing * 11x Tooth machining * 11x Light alloy lockring * Thread 27 x 1 * Weight 230g
