Final Sprint Our riders jump for the final sprint with 250 meters to go. Our Standard Rider is on 32 spoke standard wheels. Our Test Rider is on Specialized tri-spokes. Both riders jump at the same time with the same initial speed. Both riders have the same power profile (see plot below). They are identical in all other respects. Which one gets to the finish line first? The Specialized rider would be ahead by 1 meter or 0.08 seconds. Enter data for cases of interest to you. The magnitudes change, but the shape of a sprint power curve is about the same for most riders. Power as a function of time, same for both riders:  |
