If you’re on a Kickr direct drive smart trainer and have been using smaller gears in ERG mode because it is quieter, you might be missing the mark in your training sessions.
While there are lot of guides out there telling you that gear selection in ERG mode doesn’t matter, it’s not that easy. Especially when it comes to the Wahoo Kickr and the 12.5Lbs/5.6Kg flywheel.
This video explains the differences using the same power and same cadence with different gearing on the Wahoo Kickr.
The take-away: make sure you’re training in the right gear which replicates the exact kind of training you’re targeting.
