Ah, what a great feeling to have the wind blowing in your face as you ride — on your trainer — in your basement. The Kreitler Killer Kool Headwind Fan adds adjustable resistance to your Kreitler Training Station, as well as a cooling breeze to your head and body. A broad range of resistance creates the right workout for easy cruisers and the strongest riders alike. A nice breeze cools you down and makes workouts more enjoyable, but if you start to feel like you're getting blown away just turn the fan away from you and ride 'til you can't ride no more. Plus, the fan comes with a numerical chart for calculating your wattage based on the resistance created by the fan, letting you get the most out of your workout.
