Stryd Fixes Air Power
Regular readers here will know that I am normally a great advocate for all things Stryd.
However, it seemed obvious to me (and @WillM and others) that the latest air power component of overall power was wrong by a significant number of per cent. I’m surprised that Stryd let that one slip through. But they did as today Stryd confirms new firmware that lowers the overall power output (ie lower Air Power) in low wind conditions.
Today’s firmware also gives better results when you install Stryd the wrong way around. The question “Why?” springs to mind.
What’s changed?
- This firmware update brings further stability and consistency to Air Power in low air resistance conditions.
- Next Gen Stryd owners should expect that Air Power values will be lower in low air resistance environments, such as when running in low wind speed conditions, compared to firmware version 2.1.29.
- Improved support for when Stryd is placed in a reverse orientation position. (i.e. when the narrow end of Stryd is placed pointing towards the ankle instead of the toes)

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.

Stryd still has a great deal of things to fix starting with their internal calculations like this one: https://club.stryd.com/t/power-duration-curve-is-somewhat-inaccurate/23923
