This is really quite a beginner’s question, but when I train on my kickr v6, the resistance is automatically controlled via system X. So I currently always train on the middle rear sprocket. Just to be on the safe side, I would like to know whether this is sufficient or whether I should change gears.
Or is this cassette simply pre-installed so that those who want to train with the kickr v6 can do so without the corresponding control software?
The trainer has a minimum and maximum resistance. You may find for some workouts…e.g. low cadence high power, or more likely sprints, that you reach the trainer ceiling and need to change gears. I find on low cadence, high power, I need to crank up into a much harder gear too.
Although my trainer has a theoretical ,000 watt ceiling in terms of resistance, that is only if I am in one of my smallest cogs on the cassette.
What @DameLisa wrote, plus not all SYSTM workouts should be ridden in ERG mode where software is controlling resistance. You need gears to to ride in Level mode which is necessary for the Full Frontal fitness test and the HR constrained effort in Half Monty. You should also be using level mode for workouts with sprints and standing starts.
valuable extra information from @JGreengrass. Little bit more sophisticated than I originally thought ERG mode is here the keyword I think. I’m testing the Systm X right now and the full frontal fitness test is a part of it.
Sorry if this is a dumb question, but does gear selection matter in the same way and interact with the flywheel on a Kickr or Tacx Bike where the gears are virtual? I’m particularly thinking of being in erg mode with a big step change coming in power level.
