Train to your optimum level from the comfort of your home with the CycleOps Hammer Direct Drive Cycling Trainer. This powerful system utilizes your own bike so you can train with your own gear. By removing the back wheel, your bike rests on the CycleOps Hammer. Your front wheel remains in place by using the Direct Drive. This helps to prevent wear and tear on the wheel. In addition, the Direct Drive emulates a typical outdoor ride. With this, you can get the experience you need to excel in your race.
