Lightweight SRAM PC XX1 Eagle Chainfor Cyclists

In the midst of the buzz surrounding SRAM's new one-by 12-speed Eagle drivetrains, the cassette and XX1 Eagle 12-Speed Chain have undoubtedly taken center stage with their golden bling and groundbreaking technology. SRAM rose to the challenge of creating a chain that could withstand off-road abuse while maintaining smooth-shifting accuracy by investing in all-new tooling and redefining the chain-making process. The advent of 11-speed chains had raised concerns about the strength and reliability of such narrow designs, and reducing the width by another 0.35mm meant that SRAM had to work hard to develop a chain that would stand the test of time.

The Eagle chain begins with even flatter sheets than standard chains and undergoes an unprecedented 37 steps to create each plate. The result is precisely shaped pin holes that allow the pin to sit flush with the plate, enhancing security and durability. SRAM has incorporated its Smooth Link technology, which removes the inner face chamfers used to facilitate front chainring shifts. This leaves a smooth plate face that glides across the cogs quietly and reduces chainring wear by avoiding the trapping of mud against the moving surfaces. Additionally, a Hard Chrome treatment has been applied to the rollers and inner plates to further resist wear and promote longevity.

Lastly, the glittering gold bling is not merely for aesthetics. The Ti Nitride finish enhances durability and reduces friction compared to non-coated chains. Much like how anti-friction coatings have transformed suspension forks, this coating helps the chain run smoother, quieter, and more reliably over time, allowing riders to focus on the ride without worrying about their drivetrain. For those who prefer a more stealthy appearance, the XX1 Eagle 12-Speed Chain is also available in a black colorway, while still retaining all the benefits of the Ti-Nitride coating.

SRAM has clearly put a great deal of thought and innovation into the design of the Eagle chain, addressing the challenges faced by the industry's shift towards narrower and higher-performance drivetrains. The result is a product that not only looks stunning but also delivers superior performance and reliability, ensuring that riders can enjoy their off-road adventures without having to worry about the integrity of their drivetrain.
