12 Speed Cassette

The ROTOR 12-speed cassette has been engineered with all sprockets manufactured from steel to maximise durability and long-term resistance. The first four sprockets, together with the following three gears, are integrated into dedicated inner carriers to increase cassette stiffness and improve drivetrain performance.

The cassette carriers and all non-contact structural components are manufactured from aluminium to reduce overall weight without compromising strength and reliability.

As a result, the cassette weighs 658 g in the 11-51 version and 533 g in the 11-46 version. An ideal choice for training bikes, adventure riding and ultra-distance competitions, where durability and reliability are prioritised over minimal weight.
