SRAM PC-EX1 10 Speed Chain

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
