Does It Matter Which Gear I'm In?
I'm on a smart trainer in ERG mode, does it matter what gear I'm in? The answer is yes. If you are in too low a gear, you may have trouble reaching your power targets during the workouts. This is especially true for wheel-on trainers but can happen with direct drive trainers also. It will be most noticeable on low cadence intervals.
Which Gear Should I Choose?
For most of your workouts, we recommend choosing the gear that allows you to meet your recovery targets. (See My trainer won't allow me to reach my recovery targets). But if your trainer does not allow you to meet the interval power target in this mode, we recommend shifting to a harder gear on your bike during the interval, and then shifting back to your usual recommended gear for recovery. This is one of the few times where shifting in ERG mode will be necessary.
