Chains

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 11-speed chain features heavily chamfered outer plates for improved shifting and quiet running. And, with its great PowerLock connecting link, installation and removal is a snap.

The Flattop technology of the SRAM Rival chain creates a lighter, quieter, stronger chain that's compatible with 12-speed 1x and 2x eTap AXS drivetrains. Ride far, long, and fast. This chain can go the distance. - Flattop technology allows for a narrower chain with quieter operation and increased strength and durability - Use for both 1x and 2x eTap AXS - Includes Flattop PowerLock

With SRAM's X1 Chain, it's 1x11 all the time, so the chain can be narrower, stronger, faster — all because it doesn't have to deal with high-stress, front chainring shifting. Since it only has to do rear shifts, gear changes are telepathically fast and feathery light. Its "wide tooth, narrow tooth" pattern perfectly matches SRAM's X-Sync chainrings so dropped chains and cumbersome chainguides are a distant memory. The durability is impressive, too, with SRAM's Hard Chrome tech, solid pins and a proprietary link finish for improved life span.
