I’m coming from a classic trainer with a speed sensor. Using that I would tell Zwift the resistance level of the trainer and then I would use the gears on my bike to adjust the difficulty and resulting watts during a ride.
I recently purchased my first smart trainer, a Wahoo Kickr Snap, and I did a workout with ERG mode. It handled all the resistance for me, no need to change my gears.
I’m now wondering how to control the resistance of the trainer during a free ride or race. It seems that I can change my gears like I did on my classic trainer but I’m wondering if there is some more automatic way or some way through the companion app, etc. I know there is a trainer difficulty setting but I believe that deals with inclines. I’m wondering how to control the overall resistance, like on a flat.
Thanks for any help!
