I updated my Wahoo Bolt about three weeks ago when promoted.
Since then it has been consistently recording my speed as being slower then normal. First world problems I know.
I have checked this by cycling next to other people and my Wahoo is recording about 4km/h slower then them. I've also ridden recording my rides on both my Wahoo and Tom Tom watch to check adn the results were the same. Does anyhone know if there is a way to either recalibrate it or undo the last update?
Is its on a speed sensor check that you haven't got auto calibration on under the settings. It uses a short amount of GPS data to calibrate. Set the size using the erto tyre size.
Mine updated about a week ago and had been fine with uploads befits and since. Upload failure is often a sign the app has updated, but the unit hasn't. Annoying just as you want to walk out the door on a ride!
