SRAM RED AXS E1 HAMMERHEAD KAROO SHIFTERS & BRAKE CALIPERS UPGRADE KIT
Reference Number: VDXTCL
The SRAM RED AXS E1 Hammerhead Karoo Upgrade Kit includes the 2024 Hammerhead Karoo cycle computer, left and right shift-brake system controls, and flat mount brake calipers. The levers feature true one-finger braking with redesigned hoods and levers that fit all hand sizes comfortably. They offer independent adjustment of reach and contact points for a personalized setup without finger pinching or lever bottoming. Improved hood design reduces hand fatigue, and Bonus Buttons enable shifting or controlling ANT+ devices with your thumbs. The calipers are lighter and stiffer, providing excellent pad clearance for smooth, rub-free braking. This system is compatible with all generations of AXS derailleurs.
The Hammerhead Karoo bike computer combines a clear display, quality materials, and long battery life. Its intuitive hardware and software make it easy to use in any situation. It supports structured workouts, industry-leading navigation, and connects to a companion app and dashboard for easy management without removing it from the handlebars. Karoo also offers advanced control over connected bike components, including SRAM AXS products, e-bikes, and ANT+ lights.
