SRAM Red AXS D1 Chain for 12-Speed, 120 Links, Chrome

The all-new SRAM RED Flattop Chain has been completely redesigned from the ground up. Its unique link shape allows for a narrower and lighter chain while enhancing strength and providing more clearance between the outer plates and the cogs on either side. The result is a quieter chain with faster and more precise shifting performance.

The Flattop technology is a key feature of this chain, enabling a narrower profile with quieter operation, increased strength, and improved durability. The chain is optimized for SRAM's 12-speed road drivetrains, ensuring smooth and reliable shifting across a wide range of gears.

A hard chrome plating is applied to the inner link plates and rollers, significantly enhancing wear resistance and prolonging the chain's lifespan. This finish also improves shifting performance by reducing friction.

SRAM's HollowPin construction plays a crucial role in enhancing the chain's performance, durability, and weight efficiency. The hollow design of the pins, made from high-strength materials, reduces the overall weight of the chain without compromising its strength and resistance to wear and fatigue.

The chain comes equipped with SRAM's PowerLock link, which allows for tool-free chain installation and removal, making maintenance and replacement more convenient.

The design and construction of the Flattop chain aim to provide quiet and efficient performance. The unique profile helps reduce noise and ensures consistent power transfer, contributing to a more refined and responsive riding experience.

The hard chrome surface treatment applied to the chain's inner links, outer links, and rollers is a specialized technology designed to significantly enhance durability, wear resistance, and overall performance. This treatment is particularly beneficial for high-end chains like those used in SRAM's RED and Force groupsets.

The SRAM HollowPin technology is a design feature that plays a crucial role in enhancing the performance, durability, and weight efficiency of the chain. The hollow pins are engineered with precise tolerances to ensure a strong and reliable connection between the inner and outer chain links, while the use of high-strength materials provides exceptional resistance to wear and fatigue.

One of the primary benefits of HollowPin technology is the reduction in chain weight, which contributes to a lighter overall drivetrain setup, improving responsiveness and efficiency.

In summary, the SRAM RED Flattop Chain is a meticulously engineered component that combines cutting-edge technologies, such as Flattop design and HollowPin construction, to deliver a quieter, stronger, and more durable chain with faster and more precise shifting performance, all while reducing overall weight.
