12 Speed Cassette

The Rotor 12-speed components are the right choice for all those who are looking for a light and reliable 1-speed hydraulic shifting system with very variable gear steps and already have wheels with standard freewheel (Shimano HG / SRAM 10-/11-speed) feature.

The bandwidth of the Rotor 12-speed cassette is comparable to that of a 2x11-speed drive, but the system is lighter overall, more aerodynamic and nevertheless reliable due to the saved chain ring.

Like the 13-speed counterpart, the high-quality cassettes consist of a 2-part construction, whose sprocket sets are each CNC-milled from a solid block of aluminum and then assembled. This results in an extremely light weight, while meticulous and obsessive quality control ensures precise functioning.

Incredibly light weight: 11-36 teeth: 221g 11-39 teeth: 225g 11-46 teeth: 282g 11-52 teeth: 314g

  • CNC-milled 2-piece 12-speed cassette
  • Material: aluminum
  • Compatible with standard freewheels from other manufacturers
  • Fast and precise shifting thanks to the optimized Flow Ramp tooth profile
