I’ve had the same bike for a year that I use on the trainer and unknown to me the watts have been off by 100 making me appear stronger. I finally learned about zero offset calibration and now it is correct and saddening. Instead of 4.2 I’m really at 2.9 I believe. Can you change my cat in zwiftpower to match these new and correct watt readings.
Let’s just say I tried an A race and couldnt hold position for even a second against those beasts.
