Force AXS Upgrade ED Kit + Hammerhead Karoo Computer

What Our Gearhead® Experts Are Saying:

"From cockpit ergonomics to the visual layout of the Karoo, this combo delivers. I can shift and scroll my GPS right from the hoods thanks to the Bonus Buttons, and the setup process was a breeze—even with an older AXS derailleur in my system."

The Force AXS Upgrade ED Kit + Hammerhead Karoo is a smart integration of wireless shifting, high-performance braking, and modern ride intelligence. Designed for seamless compatibility with all generations of SRAM AXS rear and front derailleurs, the included left and right Force AXS Shift-Brake Systems offer precise shifting and controlled braking from the hoods or drops. Carbon levers, textured paddles, and wide Reach Adjust allow a custom fit with maximum confidence.

Bonus Buttons embedded into the shifter tops add another layer of cockpit intelligence, letting riders scroll through the Hammerhead Karoo's detailed screens or control drivetrain functions—all without releasing grip. The Karoo itself, in a limited Force Edition colorway, delivers crystal-clear maps, structured workouts, and deep customization, giving every rider command of their data and their drivetrain.

For any rider looking to upgrade a mechanical or partial AXS setup, this Force AXS + Karoo combo offers everything needed to modernize and personalize the ride. From seamless AXS pairing to effortless route navigation, it’s a complete system that’s ready for any road or gravel adventure.
