Sram Chain Pc X01 Eagle Hollowpin 126 Links Powerlock 12 Speed: SILVER 12 Speed

Sram:

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.
