Find fitness with CycleOps' Fluid2 Trainer Kit. The Fluid2 utilizes Power Band technology to generate distinct 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.
