The SunRace CSRX11 cassette has 11 speeds and an 11-34T range.
Super Fluid Drive is a design feature in bicycle cassettes intended to make shifting smoother, quieter and more efficient. It reduces chain drag and improves power transfer. This is achieved through precision-shaped gears, specialized materials such as polymer spacers, and sometimes a lighter design with alloy components for improved ride quality and durability.
