Recently my Tacx Vortex (sadly out of warrenty) broke down after having used it for a little over 5,000 kms. After some consideration and a new cable not doing the trick on the Vortex, I decided to upgrade to a better (and currently available) trainer, the Tacx Flux S Smart. Also because repairing would have had a significant cost to it as well.
My ftp on the Vortex was 243 (3.0 w/kg) and I had recently set that personal best. But the vortex wasn’t working properly for a while so I did not have it use ERG or have it adjusting resistance in any way. It was technically a dumb, smart trainer that I was biking on.
When I started using the Flux S Smart last weekend, I of course had to calibrate it, so I did on my tacx utility app and later on Zwift as well. The tacx utility app simply says: “the trainer is calibrated” and so did Zwift. I started my first ride and I was immediately very high in my heartrate but incredibly low in watts and I was truly struggling to even hold 2 w/kg. Today I tried again with the tour de Zwift ride 5 and I just felt like I wasn’t going forward at all.
Now my question is, did my old trainer just make me look really good while I actually wasn’t at all or might there still be some things I could improve on this new trainer to improve my experience on it?
Suggestions and advice are much appreciated! Thanks in advance.
