The high torque loads of E-MTBs require tough components. The straighter chain line EX1 offers allows the use of a chain that is wider and more robust than those found on drivetrains not specifically engineered for E-MTBs. The EX1 chain has been engineered to run quiet across the gear range and transmit more power to the rear wheel.
EX1 chain is wider and designed for the high-torque, heavy-duty use of E-MTB
PowerLock®
SRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect our chains. While PowerLock® does not require special tools for install, the especially tight tolerances of 10-, 11- and 12-speed drivetrains mandate that each PowerLock® is good for a one-time application only.
