> Which is good, because it turns out that lower pressure, when coupled with flexible tires, is actually lower resistance than high pressure. Yes, on rough (real world) road surfaces, rolling resistance is lower. (Ignoring aerodynamic drag of a larger tire profile.) On smooth surfaces like velodromes, skinny tires at stupid high pressures are faster. (I only bring this up because I race at a velodrome.)
