Who's it for?

The SRAM GX Eagle AXS upgrade kit is made for riders who are already running a SRAM Eagle drivetrain and want an insanely good performance upgrade at a more affordable price point. 

You won't have to splurge for a full AXS groupset with this killer solution and you'll still get all the great benefits of a premium AXS drivetrain.

Why get the GX Eagle AXS Upgrade Kit?

Wireless electronic shifting

No wires means less clutter and a new ergonomic standard that works by pressing buttons instead of pulling triggers.

Faster, more precise shifts

Enjoy fast, perfect shifting, even when climbing or sprinting. It feels so crisp and reliable that you'll never go back to cables.

More Ride Data

Use the AXS App to learn helpful data like how much you're shifting and how frequently you use each gear.


Smart AND tough. This system uses Overload Clutch Protection to protect the derailleur and hanger by disengaging the gearbox during impact, and returns right to the proper place afterwards.

Personalized programming

Suit your preference by customizing the controller to make the paddles shift up, shift down, or active a dropper post.

WaterProof and Dust proof

This is for mountain bikes after all. Never worry about a rainy or dusty ride. The GX Eagle AXS system is fully water proof and dust proof to the IP69K standard.
