SRAM XX1 Eagle - 12 Speed Chain PC-XX1 - Black Hollow pin

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 Eagleâ„¢ drivetrain’s ultra-smooth, precise, durable and quiet performance. The Eagleâ„¢ 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 CHROMEâ„¢ 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.    Groundbreaking new chain design and technology,    The Eagleâ„¢ chain has been completely re-engineered, and is produced with new manufacturing technology,    All-new Eagleâ„¢ P... - Manufacturers part number: FBA_00.2518.024.021
