SUPPLIER WAREHOUSE (add 3-6 days delivery): IN STOCK

We took the lightest and most durable chain we’ve ever made and made it lighter. With no compromises. Our HollowPin construction is lighter and stronger than a solid pin, and cutouts in the outer and inner plates drop 13 g from the previous generation. This results in a lighter, faster, stronger and more durable chain.


  • 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 
  • Super-light outer and inner plates with cut-out design
  • 13 g lighter than previous RED chain
  • Rainbow colourway available in all sizes



The SRAM HARD CHROME chain has four times 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.


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.


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.


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 increased chain strength and durability.
