I am using the following equipment:
- TACX Flux S,
- Power2Max Powermeter
- Win 10-Laptop with an Ant±Dongle and an USB extension-cable (Dongle is placed right next to the trainer).
- Most of the workouts I am doing with the smaller ring in front (34) and about 23-25-27-30 at the back.
I have the following issue:
During a SST-Training the software seems to have a problem, when the wattage is dropping from, for example, 190 watt (sst-intervall) to a cool-down-part with about 85 watt. The wattage drops, but it only drops to about 110/120 watt. Now, when I am switching from ERG-Mode to RESISTANCE-Mode and back to ERG-Mode manually, everything is fine. Now the software addresses the 85 watt and the trainer can “hold” them.
From my point of view it is not related to the “wattage-floor” of the trainer, because if I am switching between the modes manually, everything is fine. All the time my cadence is between 85 and 95.
Today I did another test (same gear-set: front 34, rear 27):
Warm up for 5 minutes with 85 watt (85 cadence): Everything is fine, the software addresses the wattage and the trainer can hold the 85 watt.
10 Minutes intervall with 195 watt (85 cadence): Everything is fine
5 Minutes cool-down with 85 watt (85 cadence): Now it happens, the wattage drops only to about 120 watt. Now shifted from 27 to 30 (rear), the wattage decreased a little bit to about 105 watt. But the wattage did not decrease to the 85 watt. --> Now I switched to RESTIANCE-Mode and back to ERG-Mode manually. The everything was fine, the software addressed 85 watt and the trainer did id as well.
Right after this, I did similar tests with Zwift. And I did not have any issues like this with Zwift.
For me it looks like, that trainerroad (in combination with the TACX FLUX S) has an ERG-Issue.
Do you have any ideas, what I can do (it is a pain to switch permanently the mode during a SST-Training g).
