I’m having an issue with the outdoor crank to measure power. I’ve read lots on here but don’t seem to have found a solution so I’m hoping for a miracle as opposed to wasting £300 on worthless power readings from Stages. Basically it seems to calibrate fine with acceptable number 917. Garmin picks up same. Then I go out cycling and push something like 240 watts at threshold for 25 mins For a whereas on the Kickr and Powertap hub in the past that would be closer to 300. Is it just the reality of the accuracy issues inherent in these things? It’s ultegra 8000 gen 3. If it is I’ll flog it online. I’m hoping someone has some methods to try and fix the problem. Thanks in advance.
