The open design of a high-strength steel alloy combined with heat-treated 7075 aluminium gives the UNO cassette an extremely rigid structure and limits the weight to a top value at the same time. The surface coating reduces friction to a minimum and thus increases the life of the cassette. Compatible with the UNO Group thanks to the Freehub technology, but also with 11x groups of Shimano and SRAM as well as compatible systems.
