These Bosch-compatible CNC-machined aluminum alloy direct mount chainrings are available in sizes 32 / 34 / 36 to complete your eKAPIC crankset. The chainrings are precision engineered for a perfect fit with the crank and motor interface. This prevents chain drops and prolongs the life of the crankset without interfering with the motor.
Universal Tooth Design
In the arms race for proprietary designs encouraging strength or efficiency of any one system or another, an often-overlooked lynchpin is the chainring. It must be compatible with the entire drivetrain, from cranks to cassette to chain and back around again. Our engineering team has finally found the solution and engineered a universal tooth profile to unlock compatibility with every 1x e-MTB groupset on the market.
ROTOR’s Universal Tooth design is compatible with SRAM®, Shimano® and KMC® MTB chains.
