The SRAM X01 Eagle AXS Upgrade Kit is a kit that will turn your mechanical drivetrain into a wireless version. It consists of a cradle, derailleur, supporting a 12-speed cassette and a charger.

The SRAM X01 Eagle AXS group takes drivetrain operation to a whole other level. From now on, nothing will interfere with the drive control. The signal from the cuff to the derailleur is transmitted wirelessly. The chain will jump to the correct sprocket literally moments after you press the handlebar lever. No more dirty armor, no more stretched out cables.

The set includes three components.

• X01 Eagle AXS rear derailleur. It supports a 12-speed Eagle cassette with a gear range of 10-50 or 10-52. It is made of aluminum and titanium, so the weight of the component is kept at the right level. Resistance to dust and water is specified by the IP69K standard. The derailleur uses the most important technologies of the American company - X-Actuation, Cage Lock, Type 3.0 Roller Bearing Clutch, X-Sync. Even so, the key is the wireless transmission of the message. Interestingly, the derailleur has a special safety feature that disconnects the overload clutch in the event of an impact. This keeps the entire component safe.

• Eagle AXS shifting handlebar. With it we change the gears in the derailleur. The buttons are very sensitive, and the signal is transmitted via ANT+ data exchange protocol. The buttons can be freely programmed. Thanks to it, it can mount a brake, drop-post handlebar or shift controller on a single clamp. The component can be attached with MatchMaker X technology.

• Charger. The battery powers the rear derailleur, charging is necessary every 20 hours or so. To refill it, just plug it into the charger for an hour.

SRAM AXS is the world's most advanced bicycle drivetrain. Thanks to the fact that the components are not connected by any cables, gear shifting is perfect. We can control the whole system with a special app. Among other things, it allows us to check the status of the battery and informs us about necessary service actions.
