Running the FMBs at that pressure, the bike was lively. Running the Vittorias at below 100 psi, the bike felt sluggish. It was only after I upped the pressure to over 110 that I found a similar responsiveness in the Vittorias.
Yeah but that is exactly what the podcast warns against, making a judgment on how the bike feels rather than hard performance data. In other words the lively feeling bike is not always the faster bike. In order to give the theory a fair shot ride a month or so with both tire pressures and check the data.
