SRAM RED CN-RED-D1 AXS 12-Speed Flattop Bike Chain

RED CHAIN

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. 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
• Requires new Flattop Powerlock

TECHNOLOGY

POWERLOCK

SRAM chain engineers developed PowerLock as a tool free, sure, and consistent way to connect our chains. While PL does not require special tools for install, the especially tight tolerances of 10- and 11-speed drivetrains mandate that each PowerLock is good for a one-time application only.

FLATTOP

To enable X-Range gearing technology, we developed a narrower chain. The unique link shape of Flattop technology not only allowed for a wider gear range, but also results in quieter drivetrain operation and increase chain strength and durability.

HARD CHROME

The SRAM HARD CHROME chain has four time the elongation (wear) resistance to our other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The HARD CHROME chain lasts longer and is just as strong.

HOLLOWPIN

SRAM employs HollowPin construction on all its top of the line PowerChains. HollowPin yields plate retention strength, front and rear shifting efficiency, and low weight benchmarks unreachable in solid pin chain applications.
