SRAM's all new 1x12-speed drivetrain is here, and very well may be the nail in the coffin for front derailleurs. Boasting a 10/50T cassette and a 500% gearing range, there is little argument at this point for 2x drivetrains. We currently have a limited stock of Eagle X01 and Eagle XX1 drivetrain parts, and we anticipate it will go QUICK due to incredibly high demand. We have also added all Eagle parts to our powerful Bike Builder, so you can now build your dream bike with a 1x12 drivetrain. Say hello to the next generation of drivetrains, and wave goodbye to the front derailleur.
