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?
I've contacted Wahoo but haven't had a reply.
