SmartRow is a precision accessory that replaces the WaterRower’s standard pulley to provide accurate performance data. Designed as a retrofit solution for existing WaterRower owners whose machines are not fitted with our patent-pending PowerPulley, it measures the force and stroke length of each pull to calculate power output, ensuring consistent results regardless of water level. SmartRow provides a reliable way to monitor training progress and compare performance across different WaterRower machines.
