Sram Red AXS Hammerhaed Karoo upgrade kit

The ultimate in cockpit data integration

Personalize your ride and your data with RED AXS controls and the Hammerhead Karoo. The carbon brake lever blade can be operated with just one finger and ensures smooth, powerful braking. The levers are designed for different hand sizes and shapes and can be adapted to your needs in terms of reach and contact point. You can use the AXS app to customise the shifting behaviour and configure two additional buttons on the sides of the levers. Use Bonus Buttons to scroll your head unit or shift your derailleur from our most comfortable controls.
