KMC’s e-Bike Solution’s chainring roller seats between teeth are perfectly matched to chain rollers for exceptional component engagement. The benefits of this unparalleled “Chain Mate” are higher power transmission efficiency and longer component lifespan. Utilizing a reinforced pin design – Shield Tech – the pin surface is raised by 10% and significantly increases 25% pin power. Chain retention prevents chain drop while also reducing friction associated with traditional narrow/wide designs.
