FE-C Smart Trainer protocol means that the trainer will be compatible with third-party apps such as Zwift or Trainer Road.
The Arion Digital Smart B+ rollers have all the standard features you would expect from a high quality roller set. The parabolic rollers give you a modern and functional design that improves handling and control and is compatible with both MTB and road bikes, while the frame includes an integrated step for easy mounting and dismounting.
Unlike traditional rollers though, the Arion has included electronics package that will completely change the way you train. The resistance is controlled via an electromagnetic unit that can handle up to 1100 watts at 20 mph and can simulate climbing grades for a more realistic road feel.
