ROTOR 12-speed cassette
The lightweight Rotor 12-speed cassette is the perfect option for a 1x12 drivetrain in combination with a Shimano 11-speed Road freehub body. The low weight of the cassette is achieved by a two-piece construction. The large sprockets are milled from a solid aluminum block and make a spider superfluous. The smaller sprockets, which are subject to greater wear due to less chain wrap, are milled from a steel block for increased durability. But it's not just the low weight of the cassette that is impressive: Rotor has optimized the gear steps for all gradation variants following intensive analysis of the performance data of cyclists from all disciplines. In contrast to other wide-range cassettes, the faster gears of the Rotor 12-speed cassette are much closer together. This makes the gear steps more harmonious across the entire range of the cassette and gives you the opportunity to pedal at your comfortable frequency even in the high speed range. This makes the Rotor 12-speed cassette particularly suitable for road and gravel use in addition to MTB use.
NOTE: The cassette is only compatible with YBN 12-speed and SRAM Eagle 12-speed (not flattop) chains.
