Saris H3 Direct Drive Smart Trainer

The all new Saris H3 Direct Drive Smart Trainer takes the previous award winning H2 and makes it better! Like its predecessors, the H3 is made from cast and machined aluminum for maximum strength and durability. The trainer is meticulously calibrated to measure power, speed and cadence and can handle 2,000 watts and replicate a 20% climbing grade. In addition, the H3 uses as a precision-balanced flywheel for the ultimate road-like feel.

The Saris H3 Direct Drive Smart Trainer also comes with some nice improvements. First up is sound. The H3 records only 59 decibels at 20 mph! To put it in perspective, that is five times quieter than previous generations. The trainer also features upgrades to its ERG mode, which is a feature commonly used with cycling applications such as Zwift and TrainerRoad. In fact, some reviewers have said the ERG mode on the H3 is more responsive than that of any other smart trainer on the market – huge praise indeed!
