Picked up my first smart trainer recently, a wahoo kickr snap, and I’m trying to figure out how to properly use it after riding on a classic trainer with a speed sensor. ERG mode workouts work great but I’m not really sure how to best use the new trainer in free rides or racing.
I believe I have to use my gears to increase or decrease the tension and therefore watts. When I shift into a harder gear I’m able to lay down the additional watts I’m hoping for. When I shift into an easier gear to try to rest or whatever things get a bit weird. The trainer is dropping the watts to about 0 and then will gradually build them up to something reasonable.
Is this drop to 0 normal? Is there a way to avoid it by doing something or is there something wrong with my trainer? Worried that I could easily get dropped in a race if this happened. Thanks for any thoughts!
