CycleOps’ SuperMagneto Pro Trainer offers smooth road-feel and four magnetic settings for dialing in the exact real-world simulation your workout calls for. The easy setting is ideal for warm ups and easy days. The road mode is tailored for high-volume rides. You can throw down with the interval setting, while the mountain mode lets you crank out intense hill workouts. Each setting has progressive resistance, where just like riding outside, resistance builds the faster the wheel spins. Plus, the frame is tough, sturdy and stable so you can ride as hard as you want.
