Mileage on Wahoo Kickr Core
Not sure if everyone else has observed this, but when in ERG mode, your wattage is obviously the same regardless of gear ratio. So when riding in say, the small ring, putting out the same wattage, the speed and distance will be dramatically different than when in the big ring.
It definitely screws up morale if in the big ring up front and smaller rear COG because the Wahoo Kickr (or the app) is thinking you are going faster even though you are putting out the same power.
