Some relatively longstanding bugs have been ironed out with Wahoo ELEMNT (reviewed here) and BOLT firmware. Specifically, I know the Assioma and PowerTap problems were somewhat annoying for a notable section of users. Anyway; all should now be good: Details are (link to: WahooFitness for firmware versions WF09-1937 & WF42-1937)
My workaround to ‘recover sensor connection’ was to press the left/system button and then press it again, this seemed to reconnect a PM.
Here is the same info, repeated below:
BOLT WF09-1937 – 3 June, 2018

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.
