The high torque of E-MTBs requires robust components. The EX1's straight chainline allows a wider and more stable chain to be used than drives not specifically designed for E-MTBs. The EX1 chain offers smooth running during gear changes and allows greater power transmission to the rear wheel.
The EX1 chain is wider and designed for E-MTB use with high torque and high load.
SRAM chain engineers have developed PowerLock as a tool-free, safe and constant way of connecting our chains. Although PowerLock does not require any special tools for installation, each PowerLock can only be used once, given the narrow tolerance range of an 8, 9, 10, 11 and 12-speed drive.
