Sram Chain Pc Xx1 Eagle Hollowpin 126 Links Powerlock 12 Speed Black

It might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. And it's also the biggest contributor to the Eagle™ drivetrain's ultra-smooth, precise, durable and quiet performance. The Eagle™ chain's links have 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. HARD CHROME™ technology extends the chain's optimal performance life, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.
