Explore this buying guide ↗Why consider this model?
- A source-based candidate for a rider considering a direct-drive trainer with app-controlled resistance, integrated ride metrics and a separately selected cassette setup.
Tradeoffs to weigh
- The 9835T box is not ready to ride with a multi-sprocket cassette: Saris lists a freehub and power supply but sells the cassette separately. Exact axle adapters and the buyer's cassette/drivetrain fit need checking, and the manufacturer listing was unavailable on the observation date.
