The KMC X11 EPT is an 11‑speed chain built for broad drivetrain compatibility, working seamlessly with Shimano, SRAM, Campagnolo, and other 11‑speed systems. Its design uses asymmetrical and additional chamfering to reduce interference and promote smooth, precise shifting.

This model features KMC’s EcoProteQ (EPT) anti‑rust treatment, offering strong weather resistance and surpassing 650 hours in salt‑spray testing. The chain is engineered with high pin strength and optimized riveting for durability and low‑maintenance performance.

Suitable for 1x11, 2x11, and 3x11 setups across road, mountain, cyclocross, and downhill bikes, it comes in an EPT anti‑rust finish and uses a standard 1/2" x 11/128" size.
