Saris H3 Direct Drive trainer

The Saris H3 is a smart direct drive trainer that boasts a sound specification of 59 decibels at 20 mph. In other words, the H3 is five times quieter than previous generations, making it the quietest smart trainer ever to leave the Saris doors. Following the legacy of Saris direct drive smart trainers, the H3 features the same reliability and durability as its predecessors. Each H3 is made from die-cast aluminum and machined from the heart of America. Inside, it houses meticulously calibrated components to measure power, speed, and cadence, along with a precision-balanced flywheel, all built to handle 2000 watts and replicate a 20% grade climb. Tested to withstand heavy training, the H3's internal cooling system will keep the electromagnetic resistance system running - and accurate - long after the legs have given out.
