Precision manufacturing and special hardening processes make these replacement e-Bike chainrings for Bosch motors extremely durable.
E-bike motors transmit extremely high torques(200 - 250 Watts) to the chain. All that torque runs through a chainring that drives the chain. Thanks to Connex 100+ years of expertise in manufacturing drive train components (they make the best bicycle chains in the world), Connex can draw on special production technologies, materials, and coating procedures to ensure that Connex e-bike chainrings will withstand these extreme loads and last longer than the others.
