The Sram Chain PC XX1 12 Speed Eagle Hallowpin Powerlock 126L Flowlink offers incredible engineering 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
