KMC X11 Chain Description: The KMC X11 chain is a very good performing and durable chain at a very attractive price. The exclusive X-bridge shaping of the plates in addition to extensive chamfering of the edges of the plates help this chain to mesh better and more quickly to gear teeth, resulting in a much better shifting quality. Solid pins that are mushroom riveted in are rugged and hold up to aggressive shifts under heavy loads. Last but not least, these chains are non-directional and are compatible with 11 speed drivetrains from Campagnolo, Microshift, Shimano, and SRAM, meaning this chain can be used on a wide range of bicycles.
