The Karoo 2 is Hammerhead’s latest cycle counter. A slimmer and lighter model than the Karoo 1, Hammerhead focused on the experience cyclists actually expect from a computer, with the Karoo 2 also being the choice of Chris Froome and his Israel Start-Up Nation team. .
Here’s a look at the five great features of the Karoo 2 – ranging from a 3.2-inch touchscreen to the ability to carry a SIM card and use mobile data on the go, there’s something to be excited about.
A breathtaking screen
The 3.2 inch screen is a key feature of the Karoo 2. The high quality screen has a color spectrum similar to that of a smartphone and a resolution of 292 PPI. This is particularly useful for providing finely detailed mapping, which might make it perfect for off-road adventurers.
The computer also has a touchscreen interface associated with buttons on the side of the device. These buttons will come in handy when fine motor control is limited – when riding over rough terrain, in heavy rain, or when wearing thick gloves, for example.

In addition, the touch screen allows you to easily move around the map. Pinch to zoom in and out and drag to move around the map adds flexibility when you’re riding.
The screen itself is protected from wear and tear by toughened, scratch-resistant Dragontrail glass, and despite the size and quality of the screen, the Karoo 2 offers up to 12 hours of battery life.
Beyond maps and routes, the screen will also show a new feature of Karoo 2 – Climber.
This provides information about the climb slope profile, remaining distance and altitude, as well as your current VAM while climbing. Whether you use it as a training tool, for running, or to explore your local climbs, it’s a feature data enthusiasts will embrace.
Seamless integration

If you’re a data lover, you’ll also appreciate the Karoo 2’s seamless integration with all of your favorite apps.
It is compatible with Strava Live Segments for those looking for KOMs and QOMs. For riders working with structured training plans, the Karoo 2 can also be paired with apps like Training Peaks to bring sessions to life on your computer.
Loading routes is also simple and user-friendly, integrating easily with all major applications.
Excellent customer support
Investing in a new bike computer can be a stressful experience, but Hammerhead offers the Karoo 2 with a 45-day satisfaction guarantee, allowing you to return it if you’re not satisfied.
If you need help or have a problem, Hammerhead also offers responsive customer support services, as well as a set of helpful and comprehensive help articles on their website, with step-by-step instructions.
Continuous improvement

The continued development of the Hammerhead team means that the Karoo 2 comes with regular software updates, with the device’s capabilities and user experience continually evolving and improving.
This keeps it on the cutting edge of cycle computer technology, with new updates rolled out every two weeks, keeping everything up to date and functional.
Complete connectivity

The Hammerhead Karoo 2 has full Bluetooth and ANT + connectivity, allowing you to pair it with all common external sensors. It will also work with most turbo trainers and can even work with electronic groupsets such as the SRAM eTap or the Shimano Di2.
Beyond Bluetooth and ANT + connectivity, the Karoo 2 also has a SIM card slot.
This gives it the ability to operate independently of your phone, with the computer accessing mobile data directly.
If you have paired it with a phone, you can also receive notifications through the Karoo 2.
