Eagle™ Technology revolutionized the mountain bike experience by offering riders a 1x drivetrain solution that is purpose-built to be lightweight, strong and intuitive, with the gear range to ride on any terrain. NX Eagle™ drivetrain is the newest addition to the Eagle™ 1x ecosystem, and shares technologies with XX1, X01 and GX drivetrains, which makes it 100-percent compatible within the Eagle™ ecosystem. NX Eagle™ delivers an ease of entry that will bring the benefit of Eagle™ performance to more riders than ever before.


SRAM Eagle™ drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. All Eagle™ components are Designed as One, to guarantee Eagle™ range, durability and performance. Only genuine Eagle™ components meet SRAM’s design directive and testing protocols. No other company can claim its product meets our design directive. Everything you need. Nothing you don’t. Engineered in Germany.

This is Eagle™.


The SRAM NX crankset delivers Eagle™ styling and performance to the newest addition to the Eagle™ ecosystem. Designed for SRAM’s X-SYNC™ 2 chainrings, the NX crankset is engineered for complete chain control—each tooth’s profile is precisely engineered to work quietly, efficiently and securely with the Eagle™ chain’s inner and outer links. DUB™ technology features a better engineered bottom bracket and a new spindle design, which together allows for a more uniform approach to bottom bracket fitment, better sealing
against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of performance and durability.

    My Sram XO 8speed system is a pound and a 1/3 lighter than this system. Where is the improvement? the 50 tooth gear for slackers?

    • Tobin Stives says:

      We are unclear about how you have your XO 8speed group set up but regardless it sounds like you are a super strong rider. The simplicity, durability, compatibility of a 1X 12speed group and the VERY affordable price of $375 a few reasons people are excited for the NX Eagle system to hit. Us included!
