The Hammerhead Karoo is an innovative bike computer with a large and bright colour display, a powerful processor and various features that will help you improve your performance! With its extensive connectivity, this computer can pair with your smartphone, the Hammerhead Companion App, smart lighting, your eBike and the SRAM AXS system, among others!
Bright colour display
Like its predecessors, this third generation Karoo computer is equipped with a large, bright 3.2-inch smartphone-quality colour screen (480 x 800 pixels). Easily browse through the Karoo's various functions, whatever the conditions, due to its combination of a touchscreen and user-friendly buttons on both sides. The various data overviews are easy to individualise and to customise exactly to your unique needs!
Precise navigation and route functions, wherever you go
The Karoo features accurate navigation and displays street names, points of interest and route data, among other things. The Karoo relies on software from OpenStreetMaps for its navigation. You can download maps for each area or country, so you'll always have the right maps with you. Did you go the wrong way? The Karoo will recalculate your route to get you back on track. The Karoo features turn-by-turn navigation for every route, using both audio prompts and visual indicators to make sure you never miss a turn. Plus, the Karoo easily syncs routes from for example Strava, Komoot, Ride With GPS or the Hammerhead Companion app.
Climbing challenges
The computer automatically recognises climbs and provides you with climb-specific, on-screen information. Climbs are detected when cycling without a route, on regular routes, routes to POIs and on detours. You can adjust the settings to show climb information at all times or only on major climbs.
Hammerhead Companion App
Easily connect your bike computer to the world wide web with the new Hammerhead Companion smartphone app.
Use the Live Tracking feature, send specific destinations, routes and workouts from your phone to your Karoo, or update your friends on your latest adventure!
Connectivity
Pair your Karoo with your favourite Smart lights, radars, power meter, heart rate monitor and even your SRAM AXS components using the Bluetooth and ANT+ connectivity. This lets you personalise your SRAM AXS set-up and easily keep track of your battery status, for example. To top it all off, the Hammerhead also pairs with your eBike and gives a complete overview of the different riding modes, range and remaining battery life!
