First of all, my native language isn’t English. So if i made a typo or grammar error, please excuse me.
Once every while I check my data between my Tacx Flux S and my Precision 4iiii left power meter. Just to see if everything is on par.
In the latest workout I noticed a large difference between the data when shifting gears.
After I saw this, I recorded a workout with both the 4iiii and the Flux and tested if the power difference is there across all gears. This isn’t the case. There are just a few gears where the wattage (ERG mode) is close enough.
I’ve tested with the workout Carillon +1. After the warmup I’ve calibrated both devices, and begin testing. I’ve started with the 34 in front and the 22 in the back.
Every next step (every 2 min’s), I’ve shifted one gear. In the first interval, 34/25 the tacx couldn’t deliver the power so I’ve ran the 22 for the first 4 minutes.
"Interval 1: ERG
Interval 2: ERG
Interval 3: ERG
Interval 4: ERG
In case you want to run the data in DCR Analyzer:
Only the 34/16 en de 50 / 16 provide the same power numbers.
Is this just a flawed Tacx Flux S? Or is there something else I’m missing.
