Have read other posts on this, but still can’t figure it out.
I am new to Zwift and smart trainers, and am trying to figure out what I should expect in terms of resistance when I ride in non ERG mode.
Tonight I did a group ride (Richmond) and noticed that something seemed to be setting the gearing on the hills, though I wasn’t shifting the physical gears on my bike at all. There were some sections where I was able to spin faster at a low gear, and others where I had to push hard at a low rpm – both on uphill.
From reading other posts, it seems like I’m supposed to physically shift my gears to handle inclines/declines, but something was clearly at work here. Another peculiarity was that I used the aero helmet bonus at some point and at first I zoomed passed everyone and then it became nearly impossible to turn my pedals over.
I’m on a Saris H3 paired via ANT+ to a MacBook Pro, using the companion app on an Android phone.
Can anyone explain what is going on? Thanks!
