The KMC X11 chain can be used with Shimano and SRAM drivetrains and is our chain of choice for all 11 speed road and MTB bikes a VeloRunner.
E bikes (especially MTB) should use the E version due to the increased Torque. 
This 11 speed KMC chain is high performing and extremely durable.
The X-Bridge technology is specially designed to enable fast, smooth and precise shifts thanks to the outer plates. Compatible with all 11 speed road/MTB systems. The X-Bridge is a new outer plate configured with precisely articulated angles for quicker and smoother gear shifting and quieter riding. Light weight shorter length pins combine with high-grade materials to reduce weight. With unique stretch-proof treatment, the durability has been effectively enhanced by reducing the attrition between inner plates and pin. As a result of this, chain life has been significantly improved.
