Chorus 11 Speed Ultra-Drive Cassette

Chorus Ultra-Drive 11-Speed Cassette Optimized 11-speed tooth design for shifting speed and fluidity. Evolved sprocket timing reduces stress on the chain and allows for easier shifting through the higher cogs. Top six cogs are divided into sets of three and are mounted on aluminum carriers. This increases rigidity by 180% and the individual cogs are 70% more resistant to torsion. Cogs are steel with a nickel-chrome treatment. Only compatible with 2015+ mechanical drivetrains and no EPS, due to chain wrap capacity.
