SRAM PCXX1 Eagle Hollowpin PowerLock 12 Speed 126 links Chain

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. Flow Link 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. HollowPin™ construction yields plate retention strength, front and rear shifting efficiency, and low weight benchmarks unreachable in solid pin chain applications. - 12 Speed - 126 Links - 252g
