You should seriously consider the "DRAFT PRO"- patent pending. As featured in numerous cycling publications. A growing group of talented riders are using the draft pro to help them conserve valuable energy in races and the hometown club peloton. May not be UCI legal. The concept is simple. Look at the DRAFT Pro meter (er red thread) and see if it is fluttering or flying straight back. Make adjustments, (left right for and aft) depending on what the meter tells you. Heck you don't even have to look at the wheel in front of you. Just pay attention to the DRAFT PRO. It acts like a laser in the dark. What better way to learn drafting for a new person than to start with what the Pros are using.
