Explore this buying guide ↗Why consider this model?
- A possible choice when you want the rear wheel to stay installed, prefer a simple unpowered magnetic trainer and are comfortable changing resistance by hand at the trainer.
Tradeoffs to weigh
- The Mag does not automatically respond to an app and its base 1020T package has no handlebar shifter, speed sensor, trainer cassette or Cog/Click. Tire and axle compatibility are narrower than the broad wheel-on label suggests.
