Time claim their new Xpresso pedal system is the “fastest pedal system in the world”. Moving from their successful iClic pedals, the Xpresso uses the same pre-open clipless system for easier cleat engagement. Instead of metal springs they use a carbon flexion blade, which makes them extremely light.
A bicycle, like all machines, obeys the laws of physics. These rules govern creation, use and dispersion of energy. In the bike’s case, the rider puts in power from leg muscles and the bike converts that effort to forward motion. This motion is resisted by rolling resistance and air drag (also gravity whenever the road points upwards). At racing speeds, air drag (which increases with the cube of velocity) is far greater than rolling resistance (which increases linearly with velocity)–the proof of that is in the current crop of time trial bikes streamlined to the limits of the rule book.
