Hammerhead Karoo 2 – Images & New Interface
Here are a few ‘leaked’ images via GCN of the Karoo 2 which show a stylised, smaller format than the original Karoo. (GCN Video link)
‘New Look’ Interface
Here are some screen dumps from the new Karoo 2 interface. The ‘new’ screen looks nearly identical to the Karoo 1, in many cases, it just looks to me like the font is a bit bigger plus some minor screen flow changes and mapping tweaks. Have a look and see what you think, whatever the breadth and depth of the exact changes this is still a sweet-looking thing of biking beauty.
I’ve covered most of the important Karoo 1 firmware releases as they happened over the last couple of years, have a look below to see how some of the more material changes have progressed over time. It’s a series of impressive, incremental improvements.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
