I’m a few weeks into a training plan and have been using my road bike on a kickr Core. If I wanted to put my gravel bike that has different gearing, would it make any difference in power performance or calculations if I’m in ERG mode? Here’s what I have:
Road bike: 700c 53/36 front, 11-32 rear.
Gravel: 650b 46/30 front, 11-40 rear.
