XX1 Eagle 12-Speed Chain

In the hubbub surrounding the release of SRAM's new one-by 12-speed Eagle drivetrains, the cassette and XX1 Eagle 12-Speed Chain have undoubtedly stolen the show with their golden bling and groundbreaking technology. SRAM met the challenge of creating a chain that could handle off-road abuse with smooth-shifting accuracy by investing in all-new tooling and redefining how chains are made.

The advent of 11-speed was met with many a pearl-clutching concern about the strength and reliability of such a narrow chain, and slimming it down another 0.35mm meant that SRAM had its work cut out to create a chain that would stand up to the miles. The Eagle chain starts out with even flatter sheets than standard chains and goes through an unprecedented 37 steps to develop each plate. The end result is precisely shaped pin holes that let the pin sit flush with the plate for increased security and durability.

SRAM incorporates its Smooth Link technology, which removes the inner face chamfers that were used to help facilitate front chainring shifts. This leaves a smooth plate face that moves across the cogs quietly and reduces chainring wear in its ability to avoid trapping mud against the moving surfaces. It also adds a Hard Chrome treatment to the rollers and inner plates to further resist wear and promote durability.

And last, but not least, that glittering gold bling isn't there solely for looks. The glitzy aesthetics come courtesy of a Ti Nitride finish that increases durability and reduces friction compared to non-coated chains. Ti Nitride does for this chain what anti-friction coatings have done for suspension forks—makes everything run smoother, quieter, and more reliably over time, so you can focus on the ride without worrying about your drivetrain. If glitz isn't your thing, the XX1 Eagle 12-Speed Chain is also available in a more stealthy black colorway that still includes all the Ti-Nitride benefits.
