Description
ROTOR cassette 12-speed
The lightweight rotor 12-speed cassette is the perfect option for a 1x12 drive in combination with a Shimano 11-speed road freewheel 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 subjected to wear by a lower chain wrap, are milled from a steel block for increased durability. But not only because of its low weight, the cassette is convincing: After intensive analysis of the performance data of cyclists from all disciplines optimized rotor the gear jumps for all gradation variants. Unlike other wide-range cassettes, the faster 12-speed cassettes are much closer together. This makes the gear jumps over the entire range of the cassette harmonic and gives you the opportunity to be able to kick your well-being frequency even in the high speed range. This makes the rotor 12-speed cassette, in addition to the MTB use, especially for the road and gravel area.
NOTE: The pictures show, except for the omission 10er pinion, 13-fold versions of identical.
