The Challenge AR features an advanced computer monitor providing the rower with measurable performance output, an ergonomically designed seat that rides on precision bearings and rollers for absolute smoothness, an upgraded footboard with advanced heel support, and an innovative soft grip handle to eliminate stress on the hands and wrist during the comfortable, but physical workout.
Outside of resistance type, we found the number-one arbiter of ride feel to be cord quality. Water ergometers tend to employ nylon cords, while air ergometers feature metal chains — a durability factor we anticipated would result in our favoring air. But while all three water rowers aced our expectation of smooth, high-tension strokes, perfecting the chain seems to be more difficult: Some tug with just a slight rumble, others feature bouncy, grinding chains that are incredibly loud, something akin to angry snoring. As for nylon, the best wind and unwind like elastic silk — no slack, no sound, no catching, just perfectly even tension throughout the stroke.
