Product Details

With the REACT series, KMC has filled a gap in its lineup of drive solutions. Just like KMC chainrings and sprockets, REACT cassettes are precisely designed to match KMC chains. This perfect synergy reduces friction between individual components and enhances the lifespan of all drive components.

Meticulously crafted ascent and descent ramps ensure precise chain guidance, improving shifting performance across the entire range. Made from high-strength steel, REACT cassettes are compatible with Shimano HG for 10 speed systems.
