Cassettes
With the REACT series, KMC has closed a gap in the programme for drive solutions. Like the KMC chainrings and sprockets, the REACT cassettes are also precisely matched to the design of KMC chains. The perfect interaction reduces the friction of the individual parts and increases the service life of all drive components. Carefully crafted ascent and descent ramps ensure precise chain guidance and improve shifting characteristics over the entire range of action. Made of high-strength steel, the REACT cassettes are compatible with Shimano HG and available in different gradations for 8- to 11-speed systems.
