Chains

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 - Compatibility: 10-speed - Chain length: 144 links

The chain is the heart of the Eagle 1x12 drivetrain, ensuring quiet operation, long life and precise shifting. It features the same link geometry as XX1 Eagle, with solid pins and a more modest finish treatment. - Not for use with front derailleur drivetrains - Links (links): 126 - Drivetrain Speeds: 12 - Chain Connection Type: Single Use Master Link - Half Link Chain: No - Weight: 260 - Compatibility: All levels of Eagle drivetrain systems

SRAM's PC-850 Chain makes a trusty partner over hill and dale. It's easy to install, too, thanks to the no-tools-needed PowerLink. Quiet, smooth, reliable and very affordable, the PC-850 is a fine value.
