ROTOR expertise in drive train design is applied to the UNO cassette, resulting in a superlight and precise piece of art. The hollow design from high strength steel combined with 7075 heat treated alloy provides a stiff structure while keeps weigth as low as possible.

Gear steps are designed to always fit your perfect cadence. Surface coating reduces friction and increase durability. It is the perfect cassette to combine with ROTOR UNO groupset but it is also compatible with other 11s groupsets, and those freehub bodies using Shimano/SRAM pattern.
