The Single Speed Disc hub is functional, easy to maintain and strong. At 244 grams, it is one of the lightest hubs on the market. The specially designed shortened cassette body is paired with mix and match spacers for maximum chain line adjustability. Standard cassette lock ring lets you run a few gears from a Shimano/SRAM cassette to turn the hub into a multispeed system. The flange spacing was designed for optimal dishing which is the balance point between wheel triangulation, spoke tension and lateral stiffness.
