I raised this over to the minions already, just waiting to hear back, so I figured I’d ask here.
Using a Kickr 2018, Windows 11 PC with ANT+ and BT. Bike is a Specialized Roubaix with a quarq PM.
In the SYSTM software, I see both the kickr and quarq as power and cadence sources, both via BT and ANT+. All as expected.
When I choose Quarq as the power source, and have a workout in ERG mode, SYSTM just can’t seem to get the power right. Like not even close, feels like ERG is not working. I see the power and cadence metrics from my PM.
If I switch the power source to the Kickr, ERG works as expected.
I can rule out issues with the trainer, power meter, and PC because if I fire up zwift on the same PC, with the same settings, using the quarq PM, zwift handles ERG perfectly.
You may ask why it’s a big deal and why I care. I just want to use the same PM for training as I do on my outside rides to be consistent.
