Re: Rider wind tunnel

If you really wanted to butt-dyno the wind resistance on a bike, you can get a large barn fan (~48" diameter) and build a tube around it with whatever. (PVC and plastic sheeting would work) Sit inside the tube with a controller switch to turn the fan on, on your bike, and get into whatever position, and turn the fan on high. Some of those fans have available wind speeds up to 20+ MPH.
