The SRAM X01 Eagle AXS Upgrade Kit offers something completely different. Riders haven’t asked for this product, because it was never possible before. SRAM didn’t employ the magic of wireless electronics for effect either. They engineered hardware with a new ergonomic experience based on touching a button rather than pushing a lever. Giving you faster, more consistent shifts. Letting you shift when you want, under load, without ever having to plan around terrain. Gathering useful data, telling you how many shifts have been made, how frequently each cog is being used, helping you make smarter choices on chainring size, and more. But just as important as what SRAM X01 Eagle AXS™ can do is how simply it does it. With intuitive and refined practicality. Built for the rider. Not the buzz. A day before the most brutal round of the Enduro World Series, Mitch Ropelato installed SRAM X01 Eagle AXS™ on his race bike. After 3,600m of descending at race-pace and some derailleur-to-rock contact that should have ended his day, this is all he said: “I never want to ride anything else.” SRAM X01 Eagle AXS Upgrade Kit Features SRAM X01 Eagle AXS Upgrade Kit is a complete drivetrain system that was developed to be an integrated high-performance ecosystem.
