Chain SRAM PC XX1 Eagle, 12-speed, 126 links

The XX1 Eagle chain is designed to combine strength, low weight, consistent performance, and smooth, quiet operation. SRAM Eagle Colorsystem offers a choice of colours including black, gold, rainbow, and copper.

Its distinctive construction increases resistance to wear. Designed and manufactured at SRAM factories in Europe, it is described by the manufacturer as the quietest, strongest, and most wear-resistant chain in the world.

Technologies

PowerLock – developed by SRAM chain engineers as a reliable and consistent way to connect a chain without tools. Although PowerLock does not require special tools for installation, the particularly strict requirements of 10- and 11-speed systems mean that the connector can be used only once.

Hard Chrome – SRAM Hard Chrome chains are four times more wear-resistant than other SRAM chains. This is due to the finishing process used on the inner links and rollers. Pin strength and overall strength are equal to those of current SRAM chains. Hard Chrome chains last longer and are just as strong.

X-SYNC – SRAM X-SYNC 1x chainrings provide performance and durability. The tall, square tooth edges of SRAM X-SYNC engage the chain earlier than conventional triangular-shaped teeth. The sharp, narrow tooth profile and rounded, chamfered edges help manage a damaged chain. Designed for muddy routes, X-SYNC chainrings have mud-clearing recesses for the inner chain links and rollers. Designed in Germany, X-SYNC chainrings are an integral part of the SRAM 1x system.

Eagle – SRAM 1x drivetrain system technology. Eagle is a lighter, simpler, more durable, and easier-to-use system. It includes 1x components designed for increased durability and performance while maintaining a significant weight advantage over other system technologies. Eagle technology provides a 520% wider gear range, equivalent to a 2x11 drivetrain.

Flowlink – the exceptionally smooth inner chain links have no square edges, allowing the chain to engage with the cassette and chainring with much less friction, resulting in quieter operation and longer service life. This construction enables a narrower overall profile that can handle greater angles, as well as flatter outer links, for more consistent chain operation and greater overall strength.
