CycleOps Fluid 2 Bike Trainer

CycleOps Fluid 2 Trainer is designed with Power Band technology to allow distinct resistance level changes without reaching to a lever on the unit. Resistance level varies automatically based on your cadence and wheel speed directly by using your bike's own gears. More power allows for intense interval and strength building workouts. Cooling mechanism increases life of the resistance unit. Power varies from less than 20 watts to over 725 watts (at 22.5 mph). Ideal for hitting and maintaining specific heart-rate targets. The patented design gives you the quietest ride with the best road-like feel. Includes training DVD.
