Rotor UNO 11 speed Kassette

The Rotor UNO cassette is extremely lightweight at a staggering 134 grams. Besides the bizarrely low weight, the cassette shifts perfectly and is highly durable. The cassette is made from a single piece of milled steel from the 11t up to the 21t. The 24 and 28 are both made from a single piece of aluminium. The surface of the cassette is completely coated, ensuring a longer service life and reducing the amount of friction between the cassette and chain. Ideal in combination with a Rotor UNO groupset.
