SRAM PCEX1 Powerlock E-MTB 8 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 quietly across the gear range and transmit more power to the rear wheel.
