The Killer Kool Headwind Fan is an adjustable resistance unit that runs off a belt coming from the front drum of your Kreitler Rollers. The Headwind Fan has several functions. The main function is to add resistance. An adjustable air inlet controls the amount of resistance desired. When closed, the additional resistance is minimal. Wide open, the resistance is high enough for even the strongest riders. Check out the Wattage Chart (will open in a new window) for a numerical representation of the resistance created by the Headwind Fan.
The second function is to provide a cooling breeze. The Fan unit can be rotated to point the airflow high or low, and adjustable louvers can fine tune the side-to-side direction. Staying cool will make your workouts more enjoyable and is less stress on your body. The Fan attaches to the front left side of the Frame. You can also direct the airflow away from you if desired.
