Saris H3 Direct Drive Smart Trainer

With the H3 Direct Drive, Saris wanted to make the most quiet indoor trainer ever created. The H3 is a remarkable 5 times quieter than the previous generation trainers. The H3 still features the same reliability and durability as it's predecessors, featuring cast and machined aluminum sourced from America. Internal components are meticulously calibrated to measure power, speed and cadence. Combined with a precision-balanced flywheel, all aspects of the H3 are built to handle 2000 watts and replicate a 20% climbing grade. Tested to withstand heavy training, the H3’s internal cooling system will keep the electromagnetic resistance system working and accurate long after your legs have given out.
