Having major issues with training at the moment. I have a Tacx Vortex smart trainer, about 2 years old. Never had an issue.
This week I’ve been training and noticed the Cadence has been inaccurate and dropping to below 40rpm, and at other times speeding up to +160rpm. This is whilst peddling a consistent 90rpm. I tried pairing up with my third party cadence sensor and got the same results.
It initially felt like the power reading was accurate but today it was way below what I was peddling. In addition, when I sped up my cadence and pushed harder, the turbo decreased resistance and I end up spinning without putting any power down.
I’ve updated the Tacx firmware, updated Zwift, and played around with the difficulty settings all to no avail.
My next course of action is to delete Zwift and its files entirely and start again, unless anyone has a better idea?
