The Saris (formerly known as Cyclops) H3 is a direct drive fully interactive smart trainer. Saris claims it is five times quieter than previous generations and quotes 59 decibels at 32km/h.
The trainer automatically measures power, speed, and cadence all from the same Bluetooth or ANT+ connection. It can handle up to 2000 watts and provides an accurate road feel on gradients up to 20%.
The trainer supports thru-axle and quick-release out of the box. The realistic road feel is generated by the 20 lbs flywheel.
The legs on the trainer fold up and it is designed with a handle so it can be easily moved out of the way when not in use. It comes with a Shimano/Sram freehub and XDR freehubs are sold separately.
Direct Drive smart trainers are the best way to keep your motivation up during the winter months. They provide the best integration and immersive feel when connected to third party apps like Zwift.
