Product details:

A clean gear change is influenced by all components of the circuit, but only the optimal matching of cassette and chain makes this work reliably and silently. In the optimized design of the PowerGlide 1170 cassette, SRAM has 3 sprockets mounted on a spider, which leads to lower weight and higher stability. This creates a cassette that shifts efficiently and safely in all situations. Compatible with SRAM RED 22 and 1170 11-speed chains. Requires Shimano 11-speed compatible rotor. The 11-36er gradation is specially designed for the Force 1 group with X-Horizon technology.Cassette design for exceptional gear shifting with even quieter cassette/chain operation.
Lightweight, durable and efficient half star design.
Sprocket with 16 teeth (except for WiFLi: 14 teeth).
Conforms to ISO 4210.
