Just received a response from 1UpUSa:
"Sorry, for the delayed response. Our progressive resistance works great for novelist type riders looking for a smooth feel and extra quiet. It's not designed for 1-2 hr sessions with high power for the duration. We do not have any adjustment for the resistance."
Guess that settles that.
Let's change the subject to what's your favorite trainer and why. Self-funded so budget is important.
