The ROX 12.1 EVO can be connected to a Smart Indoor Trainer via ANT+ FE-C. Here you have different
modes in which you can use the ROX 12.1 EVO together with the Smart Indoor Trainer.
Passive
Select this option if you want to use e.g. the ROX 12.1 EVO as a data logger, because you use e.g. Zwift,
Ruby or Bkool in parallel.
Target power
You can also control a workout with the ROX 12.1 EVO by entering a target power.
Here, the Smart Trainer automatically regulates the resistance depending on the cadence. You can
change the desired target power via + and -.
Resistance
Should you select the resistance mode, you can control the ‘braking effect’ of the Smart Trainer. This is
adjusted in 10% steps and can be conveniently set via the display.
