If there was one thing I was clear about before starting the Granguanche route in the Canary Islands, it was that I needed a reliable, easy-to-use GPS with good battery life. And that´s where the new Hammerhead Karoo comes in.

When you´re looking for a GPS for gravel riding, you want it to be easy to use, reliable, and one that won´t let you down in the middle of a ride. To test the limits of the new Hammerhead Karoo, I decided to replicate the Granguanche route in the Canary Islands with a group of friends—an adventure with all kinds of terrain, elevation changes, and constant navigation. After many kilometers of use, I can say that this device not only delivers, but excels in key areas that make riding with it much easier and smoother.

First impressions

From the first moment you touch it, you can notice the leap in quality. The construction is solid, and the screen has improved significantly, not only in resolution but also in fluidity and ease of use. Navigating the menus is more intuitive than ever, and the overall experience is much more streamlined and comfortable than in previous versions.

Autonomy for long routes

The battery is one of the aspects that surprised me the most. It easily endures long periods of pedaling, even with navigation and sensors connected. During my Granguanche replica, this was key, because I spent many hours without access to power outlets and the Karoo continued to function without worry. You can explore, navigate, and adjust settings without the battery becoming a limitation.

Simple and intuitive navigation

If there´s one thing that stands out about this device, it´s how easy it is to navigate the menus and manage routes. You don´t need to be a tech expert to get the most out of it from day one. Plus, its integration with the maps app is a strong point: if a friend sends you a location, just open it on your phone and with one tap you´ll have it directly in the Karoo. No complications, no wasted time.

Integration with the Sram AXS ecosystem

This is where it really makes a difference. If you have multiple bikes with SRAM AXS components, the Karoo automatically recognizes which one you´re using and adjusts the data without manual configuration. No need to remove or deactivate sensors every time you change bikes. Plus, you can calibrate the power meter, adjust the drivetrain, and switch between screens with a single click from the device itself.

Conclusion

After many test miles, I´m convinced this GPS is the easiest, most accurate, and most comprehensive I´ve ever used. Its display, battery, and integration with the SRAM AXS ecosystem make navigation and data management on the road smoother than ever. If you already use SRAM components, this Karoo is the missing link in your setup.
