Explore this buying guide ↗Why consider this model?
- A possible fit for a rider who wants a mechanically simple, unpowered wheel-on trainer and is comfortable choosing gear and cadence to vary the progressive fluid resistance.
Tradeoffs to weigh
- The base SKU does not automatically respond to an app and does not supply a speed/cadence sensor or a measured power figure. Tire noise, traction and fit depend on the exact bicycle and setup, while axle adapters and a trainer tire are separate purchases.
