SRAM introduced the first-ever, purpose-built 1x drivetrain, and is the absolute leader in 1x technology and innovation. We have manufactured, tested and ridden hundreds of thousands of SRAM 1x™ drivetrains, and have capitalized on the lessons learned from our experience to create all-new drivetrains with Eagle™ Technology. Eagle™ drivetrains provide unparalleled performance, enhanced toughness and durability, and the freedom of a 500-percent gear range. Learn more here → http://bit.ly/SRAMeagle
