From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
Dan Patch broke world speed records at least 14 times in the early 1900s. In 1905, he set a world's record for the fastest mile by a harness horse (1:55 1 ⁄ 4 – 1 minute, 55 + 1 ⁄ 4 seconds) that stood unmatched for over 30 years. Unofficially, Dan Patch broke this record in 1906 with a clocking of 1:55.
The distance used for calculating the overall speed record is usually the distance in a straight line. [2] In the case of man-powered races, overall speed record doesn't always reflect the best performance. It is highly dependent on technological advantages generating the speed of the craft, vessel or vehicle. [3]
