Elite Qubo Adjustable Fluid Trainer. The Elite Qubo Adjustable Fluid Trainer provides the means to maximize the effectiveness of indoor training sessions. Its progressive fluid resistance unit ensures a smooth, quiet, road like feel and the handlebar shift lever lets you choose from five different levels of resistance for intense cardio workouts or strength building sessions. The Qubo frame utilizes Elite's Crono System which factors in a rider's weight and power to individualize the workout and better simulate riding on the road. With the Crono System, the weight of the rider rests directly on the roller as it would happen on the road, having an influence on the effect of a rider's power output. The Qubo 's Fast Fixing system allows clamping and release of the bike with a single hand while the trainer folds down easily when not in use.
