Hammerhead Karoo 3 Cycling Computer

The Hammerhead Karoo cycling computer represents the pinnacle of innovation, design, and performance. The stunning screen, premium materials, and all-day battery life combine to make Karoo a cycling computer without compromise. Easy to use in every condition thanks to thoughtful hardware and software design, Karoo allows cyclists to focus on the road - and the ride - instead of their equipment.

Featuring comprehensive structured workout support, industry-best navigation, and a Companion App and Dashboard that let cyclists manage their Karoo without removing it from the handlebars; Karoo helps riders hit their training goals, explore new routes, and enjoy every ride. The pièce de résistance is Karoo’s unparalleled control of the bike’s connected components, from SRAM AXS products to E-Bikes to ANT+ lights.
