We reimagined the cycling mounting system from first principles to create a new standard that is reliable, easy to use, elegant, and aerodynamic. It is also backwards compatible with standard Quarter Turn designs. The result is the patent pending Hammerhead Mounting System (patent pending).
The Karoo to Quarter-Turn Adapter allows you to put the Karoo 2 on any Garmin-compatible bracket, making Karoo 2 backwards compatible.
The low profile Hammerhead Mounting System (patent pending) is elegant and aerodynamic.
The Hammerhead Mounting System (patent pending) presents a far greater contact area between the head unit and mount making it intrinsically stronger than a quarter turn design. Its teardrop shape looks elegant on your bike when your Karoo 2 isn’t mounted.
Karoo 2 slides into the Karoo Mount with an affirmative click. This allows it to be closer to the stem and easier to mount in tight spaces. It disconnects through rotation that requires overcoming two points of friction to prevent unwanted dismounting.

Karoo 2 Replacement for Garmin Edge
Replaced my Garmin Edge 1000 after the side button perished on the unit. After so many years of using the Garmin Product Edge 500 and 1000, you het used to some features. Some of these would be nice if they can be integrated into the Karoo 2. Love the unit and its display. Temperature and grade display would be nice as a decimal point rather than a whole number. Some Calorie display from my workout without having the power meter. Might be one of the display items but have not been able to find it. I am not a fan of the rubber plug at the charging port. Have not used the maps yet and have to say that I never used the Garmin Maps either. It's perfect replacement for my Garmin at a better price. I don't have great eyesight and changing between long distance and short distance vision I can make out the display readings. The unit is smaller than the edge 1000 but the display is pretty much the same size maybe even a little bigger. Love the fact I can utilise the existing mounts. Makes it easier with my 5 other bikes and I don't have to replace them. Perfect system for the Garmin replacement. Any future options for silicone covers to protect the unit would be welcome just in case you do drop the unit. Very happy with the Karoo 2 so far. I was going to get the heart rate sensor with the unit but they were out of stock when I bought my unit. Few other options were not available online as well. Probably would have taken advantage of some bundles. That aside, great unit and certainly would recommend it to anyone wanting a lower cost alternative to the Garmin.
Free return and full refund if you don't love your Karoo 2
Available 7 days a week to ensure you get the most from your Karoo 2
