The KMC 11-speed cassette in 11-42T pairs a wide gear range with hardened steel durability, making it a smart choice for 11-speed MTB, gravel, and e-bike drivetrains that face varied terrain. The ED Black coating guards against corrosion, and the hardened steel cog construction stands up to the elevated torque loads common on electric-assist bikes.
