KMC Bosch Gen4 chainring

KMC Bosch Gen4 Direct Mount Chainring (38T, 12s)

Elevate your e-bike´s performance with the KMC Chainring, meticulously engineered for Bosch Generation 4 drive systems. Designed for riders who demand reliability, efficiency, and durability, this premium chainring is the ultimate upgrade for your 12-speed e-bike. Unleash the full potential of your Bosch motor with a component built to withstand the rigors of high-torque electric-assist riding, ensuring a smoother, more responsive, and longer-lasting drivetrain.

This KMC chainring is purpose-built to integrate seamlessly with your Bosch Gen.4 e-bike, providing a flawless connection that translates every watt of power from the motor and your legs directly to the trail or road. The Direct Mount design not only offers a clean, modern aesthetic but also creates an incredibly stiff and secure interface with the crank arm. This eliminates flex and ensures maximum power transfer, giving you a more connected and powerful feel with every pedal stroke. Whether you´re tackling steep technical climbs or accelerating on flat terrain, you´ll notice the immediate improvement in efficiency and responsiveness.

One of the standout benefits of this chainring is its advanced tooth profile, specifically optimized for 12-speed systems. This design ensures exceptional chain retention, dramatically reducing the risk of dropped chains even on the roughest terrain. The teeth are shaped to perfectly engage with the inner and outer plates of your 12s chain, providing a secure grip that inspires confidence on every ride. This superior chain management works in harmony with your rear derailleur´s clutch mechanism to deliver a quiet, stable, and reliable drivetrain performance.

Installation is streamlined and straightforward thanks to the spacer-free design. The chainring is engineered with a precise 4.5 mm offset to achieve a perfect 47.5 mm chainline, which is critical for optimal shifting performance and minimizing wear on your cassette and chain. This perfect alignment ensures smooth gear changes across the entire 12-speed range, reduces drivetrain noise, and extends the life of all your components.

Built to handle the increased torque and mileage associated with e-bikes, this KMC chainring offers exceptional durability. It is constructed to resist wear and tear, providing thousands of miles of reliable service. If you are looking to replace a worn-out component or simply upgrade for better performance, this chainring represents a smart investment in the longevity and enjoyment of your e-bike.
