Rotor 12-speed Cassette

The high-quality and extremely light 12-speed ROTOR cassettes with Flow Ramp cassette tooth profiling are assembled in Spain from 2 parts, which are each milled from the full block. This results in an extremely low weight with the most precise function.
The UNO Group’s previous many years of product development and manufacturing experience, INpower power meters, cranksets and hubs, has given Rotor engineers a deep understanding of the powertrain transmission. The knowledge about the development of solutions to optimize the pedalling power of cyclists and the know-how in CNC machining made it possible to incorporate this knowledge into the design of the cassettes in particular.


Features – 12-speed Cassette

  • Cassette teeth profiling based on ROTOR’s years of experience with Q Rings ensures optimized shifting
  • The cassettes offer a larger bandwidth and optimized sequencing for better ranges
  • Large aluminium sprockets – CNC machined from a full block – for maximum precision and minimum weight
  • Reinforced steel body – best possible durability at low weight, milled from one piece
  • More even gears for the toughest climbs with more range to push harder on flat or fast descents. – True Cadence is the keyword for this technology
  • Rotor´s innovative Flow Ramp cassette tooth profiling gives you control over your shifting process in the desired situation and speed
