From keeping better track of our performance to trying to take our training to the next level, the 4iiii Shimano Dura Ace 9200 PRECISION 3 Pro Dual-Sided Power Meter is one of our favorites for keeping track of our workouts. The 4iiii Shimano Ultegra 8100 PRECISION 3 Pro Dual-Sided Power Meter has Bluetooth and ANT connectivity, so we can sync our workouts with our cycling computer or training apps. The dual-sided power meter can track watts, cadence, cycling metrics, calories, left/right balance, pedal smoothness, and torque effectiveness for complete performance metrics. Apple Find My capability allows us to keep track of our bike when we aren't with it, and an Automatic Terrain Selector reads the terrain we are on and offers a more responsive cadence and power feedback/data. This power meter has a 550-hour battery life, so we never have to worry about running out of battery, and is IPX7-rated waterproof so we can track our stats no matter the weather.
