Sram Chain PC-XX1 Eagle 12 Speed 126 Link Gold or Black

The internal engineering in this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains. Also the biggest contributor to the Eagle drivetrain's ultra-smooth, precise, durable and quiet performance. With a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength.

• Groundbreaking chain design and technology
• Completely re-engineered and produced with new manufacturing technology.
• Eagle Power Lock chain connector with FLOWLINK technology provides better chain-guiding and increased longevity
• Quietest, strongest and most wear-resistant chain in the world
• Significantly improved wear resistance on Eagle cassettes and rings
