SRAM X01 Eagle AXS Upgrade Kit

What it is

Ready to ditch cables and feel the future of shifting? The SRAM X01 Eagle AXS Upgrade Kit brings the precision of electronic wireless shifting to your mountain bike, giving you lightning-fast gear changes with just a tap of a button. Built around SRAM’s proven Eagle 12-speed system, this kit makes the jump to AXS simple, just add it to your current Eagle drivetrain and ride.

Who it’s for

This kit is made for mountain bikers who want the reliability and toughness of SRAM X01 with the instant response of wireless shifting. If you already run a mechanical Eagle drivetrain, it’s your ticket to the same setup the pros trust, without replacing your whole groupset.

Why we like it

We love how clean the bike looks without cables snaking across the frame, and how every shift feels crisp, consistent, and effortless, even under load. The system is weather-sealed and tough enough for real-world abuse, which means less fiddling and more riding. The rechargeable battery is simple to swap and lasts surprisingly long between charges.

Why you’ll want it

Once you try AXS, you won’t want to go back. Every climb and descent becomes smoother, every shift more predictable. No more worrying about stretched cables or barrel adjusters, just reliable shifting you can trust in the middle of a race or deep into the backcountry. Plus, setup is quick, and you’ll enjoy the futuristic feel of tapping a button to drop into gear.
