10,000km+:
Lasts. And Lasts. And Lasts.

The 10,000km+ drivetrain is the solution for frequent riders. The combination of our e101 EPT/eCargo1 chain with one of our 3mm wide sprockets and chainrings guarantees a mileage of 10,000km+.

KMC e101 EPT

For the e101 chain, we have embraced the classic design of the bushed chain. The highest quality materials, in combination with this elaborate construction, make the e101 chain extremely durable and provide an unsurpassed life cycle.

KMC's EcoProTeQ technology (EPT) protects chains against corrosion for twice as long as conventional rust protection, setting new standards. Each component of every chain link is individually treated with EPT. This results in a 100% coating that offers the lowest susceptibility to water, salt, and air humidity. Another characteristic of EPT is its very smooth surface, providing chains with excellent running qualities. Long-term dirt build-up is minimized, significantly reducing the need for chain maintenance.

KMC eCargo1

eCargo1 – the heavy-duty chain for the most demanding applications. With a tensile strength of 1,350 Nm, the eCargo1 exceeds the required standard by 150%. This allows the chain to withstand the immense forces exerted on the drivetrain of a cargo bike, stemming from high engine torques and heavy loads. When combined with KMC sprockets and chainrings designed to match, it becomes the perfect solution for rugged everyday use – even on non-motorized cargo bikes.
