Find fitness with CycleOps' Fluid² Trainer Kit. The Fluid² utilizes Power Band technology to generate distinct fluid resistance changes seamlessly without the use of a lever. The large flywheel delivers a smooth, realistic road feel while sturdy legs provide a stable platform for pumping out hard, 600-watt efforts and out-of-the-saddle climbs. A favorite among serious racers, the Fluid² is easily transportable and stands up to repeated punishment by the burliest of legs for years of impressive performance. Two climbing blocks are stackable to simulate steep grades, a RealRides training DVD will keep you motivated, and the Trainer Mat and Bike Thong sweat guard protect your equipment and floor.
