Smart Trainer

The 4iiii Fliiiight smart trainer uses a unique resistance mechanism to directly create resistance within your wheel rim without touching it. This eliminates nearly all sources of noise within a conventional trainer: there are no gears, pumps, or belts to generate mechanical noise and reduce accuracy.
