So I upgraded from my tacx flow smart to a tacx flux s, I used it for the first time today with Jepson today in ERG mode as normal.
It was a very different experience and one that I did not enjoy. With the wheel on flow I never had to leave the big ring, I may have been a few watts over my recovery targets but no big deal, rest of time I was in the middle of the cassette.
But tonight I had to change to my lowest gear for every recovery interval, if I went back to big ring middle of cassette for the hard intervals I wasn’t constantly about 10% over target and was forced to change gear.
Also the intervals seemed much tougher than normal, I tired them in both big ring and small ring. When in the small ring the power reading were also a lot less smooth than the big ring. I’m pretty sure my cadence was consistent.
It just felt like the power was wrong compared to the flow and riding out doors. So I’m wondering am I missing something or has the much cheaper flow been wrong the whole time? Also I’ve never used my actual power meter on my indoor trainer.
I have the latest software installed.
Anyone any thoughts or is there really such a big difference between wheel on and direct drive?
