Zwift hub appears to have lost the ability to sense speed. It’s showing approximately half speed of what it should and this makes my Watts very low. I have to stay in the highest gear all the time unless I am on a very steep grade.
When I a calibration no speed shows up at all and therefore cannot calibrate.
Any ideas? It seem to be a speed sensing problem… i can only develop speed in a ride, it wrong but there, however, I cannot develop any speed in the calibration function to attempt to fix this???
