KMC X12 chains feature a double X bridge shape for fast and smooth shifting. - Compatible with SRAM 12-speed systems - Double X bridge shape with inner and outer plate chamfering for smooth and fast shifting - Mushroom riveted pins for the highest pin power and allows shifting under heavy loads - 1/2 x 11/128 - 126 Links

SRAM's PC-1 Single Speed Nickel Chain is designed for singlespeed bicycles so it won't jump off when you're laying down the power. It comes with a connector link for easy installation and removal.

The PC-951 is SRAM's most economical PowerChain and maintains their high standards of quality. It boasts tough chrome-hardened pins for durability and accurate shifting. And, with its great PowerLink, you don’t even need tools to install it.

SRAM’s 10-speed chain is compatible with all industry-standard 10-speed systems. And, with its great PowerLock connecting link, installation is a snap.

The basis of every Eagle drivetrain is its chain—and the NX Eagle chain is designed and manufactured using genuine SRAM Eagle architecture, so it is fully compatible with every other component in the Eagle ecosystem. The NX Eagle chain features solid pin construction, Eagle PowerLock, and smooth, efficient shifting that you can count on every time out. Features/Specs - Eagle PowerLock chain connector with FLOW LINK technology provides better chain-guiding and increased longevity - Unique features and design also provide significantly improved wear resistance on Eagle cassettes and rings - Weight: 278g (126 links) - Material: steel - Speeds: 12 - Compatibility: All levels of Eagle drivetrain systems

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

The all-new SRAM RED chain was redeveloped from the ground up. The unique link shape allows the chain to be narrower and lighter while increasing strength and providing more space between the outer plates of the chain and the cogs on either side. The result: a quieter chain with faster, more precise shifts. - Flattop technology enables a narrower chain with quieter operation and increased strength and durability - Hard Chrome plated inner link plates and rollers for reduced wear and prolonged life - HollowPin construction for increased strength and efficiency - Chain length: 114 links
