TECHNOLOGY
HARD CHROME
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.
Flattop
To enable X-Range gearing technology, we developed a narrower chain. The unique link shape of Flattop technology not only allows for a wider gear range, but also results in quieter drivetrain operation and increased chain strength and durability.
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.
PowerLock
SRAM chain engineers developed PowerLock as a tool free, safe, and consistent way to connect our chains. While PL does not require special tools for install, the especially tight tolerances of 11-speed drivetrains mandate that each PowerLock is good for a one-time application only.
