SRAM PC-XX1 Eagle 12-Speed Copper Hollow Pin Mountain Bike Chain

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 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.

Eagle technology represents our newest lx drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new lx components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.

Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.

• 1 by 12 chain designed for optimal performance with SRAM Eagle drivetrain
• Smooth radius outer links yield reduction in noise, friction and wear on chainrings and cassette cogs
• Flat plate design provides better rivet connection for improved strength
• HARD CHROME technology with a Titanium Nitride coating extends chain life and further reduces friction
• 12-speed Powerlink Flow Link included
