The Hammerhead Karoo 2 prioritizes and elevates your riding experience. Intelligently designed to resolve limitations from other computers on the market, the Karoo 2 features a Smartphone quality touchscreen, massive internal storage, IP67 dust and waterproof rating and full cellular, bluetooth and ANT+ connectivity.

Smartphone Quality Display
The Karoo 2 brings an enhanced smartphone quality touchscreen experience to your cycling computer. Navigate maps and commands with ease thanks to the fully responsive 3.2" touch screen that boasts the largest color spectrum on the market and twice the pixel density (292PPI) of its closest rival. Dragontrail Glass with an etched matte finish ensures the Karoo 2 is durable, resilient and visible in all light conditions. Additionally, the Karoo 2 is fully controllable through buttons for whenever a touch screen is not desirable.

The Karoo 2 is designed from the ground up to offer the most user-friendly cycling computer experience. Easily create routes directly from the Karoo, or download routes from any website using the Chrome Extension, or sync and share routes through complete social media integration. On top of connecting to WIFI, bluetooth, ANT+ and GNSS sensors and devices, the Karoo 2 can even connect to cellular band coverage using a separately sold SIM card. The Karoo 2 works just as well inside as out, with Smart Trainer Support which allows the Karoo 2 to connect with, and control your smart trainer based on your workout as well as displaying its data.

Rugged Durability
Take the Karoo 2 anywhere, on any adventure without any risk to your navigation, data collection or the longevity of the Karoo 2. The body of the Karoo 2 is overmolded with a shock reducing bumper, is both dust and waterproof, and includes a waterproof SIM card cover so you can take the Karoo 2 on the gnarliest adventure without worry.
