DESCRIPTION The SRAM PC-1170 chain features more heavily chamfered outer plates for improved shifting and quieter running. The chrome hardened pin construction provides longer chain life.

DESCRIPTION The basis of every Eagle drivetrain is its chain-and the NX Eagle chain is designed and manufactured using genuine SRAM's Eagle architecture, so it is fully compatible with every other component in the Eagle ecosystem. The NX Eagle chain features solid pin construction, Eagle PowerLock and smooth, efficient shifting that you can count on every time out.

The strongest system is a chain with no weak links. Eagle chain links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. And it’s also the biggest contributor to the ultra-smooth, precise, durable and quiet performance found in the 10-50 tooth cassette and X-SYNC 2 chainrings. Installation is made easy with a dedicated 12-speed Eagle quick link.
