KMC REACT 11 speed 11/42T BOX cassette

The 11-speed KMC REACT cassette delivers excellent shifting performance, both upshifting and downshifting, thanks to carefully integrated uphill assists. The cassette's visual appeal is truly eye-catching thanks to its black coating on all sprockets, and its robust construction made of high-strength steel makes it ideal for e-bike use. With the REACT series, KMC has filled a gap in its drivetrain offerings. Like KMC chainrings and sprockets, REACT cassettes are precisely engineered to match KMC chains. This perfect synergy reduces friction between individual components and increases the lifespan of all drivetrain components. Meticulously crafted entry and exit ramps ensure precise chain guidance, improving shifting performance throughout the entire range. Constructed from high-strength steel, REACT cassettes are compatible with Shimano HG freehubs and available in a variety of configurations for 8- to 11-speed systems. 11-13-15-17-19-21-24-28-32-36-42T For Shimano HG systems Perfectly matched to KMC chains Hardened steel Item no.: BCS111142 Color: Black
