Never miss a workout due to weather or time constraints. CycleOps’ Fluid2 Power Trainer Kit has everything you need for precise workouts. The fluid resistance provides high-quality, stable, smooth rides. You can maximize those workouts with the PowerCal, which uses heart-rate-based algorithms to calculate your power to within +/-5%. Monitor your numbers with the ANT+ compatible Joule, which has a total of 18 field metrics. Each of the three customizable screens shows three field metrics and two sub-fields, allowing you to keep track of your effort without having to constantly toggle back and forth. Take the Joule and PowerCal outside when the weather clears up to continue your hard work.
