ROTOR cassette 12-speed
The light rotor 12-speed cassette is the right option for a 1x12 drive in combination with a Shimano 11-speed road freewheel body. The low weight of the cassette is achieved through a two-part construction. The large sprockets are milled from a full block of aluminum and make a spider superfluous. The smaller sprockets, which are more exposed to wear due to a lower chain wrap, are milled from a steel block for increased durability. But the cassette is not only convincing due to its low weight: After intensive analysis of the performance data of cyclists from all disciplines, Rotor optimized the gear jumps for all gradation variants. In contrast to other wide-range cassettes, the faster gears are much closer together in the Rotor 12-speed cassette. This makes the gear jumps over the entire bandwidth of the cassette more harmonious and gives you the opportunity to pedal your wellbeing frequency even at high speeds. This makes the rotor 12-speed cassette, in addition to MTB use, particularly suitable for the road and gravel area.
NOTE: The illustrations show the identical 13-speed versions, except for the omitted 10-pinion.
