+1, A 451-32 tire wont slow you down any more than a 622-32 will , you are just turning the wheel around more often

Per Mile, than the Bigger Wheel.. Higher gear to achieve the same speed proportional to the wheel size..

acceleration will feel Quicker with the Smaller wheel..

Bike Friday's Pocket Rocket is Quite like it is called..

Biggest source of drag is the rider's body air resistance, .. a constant, if the same guy is on the saddle, pedaling,

which you all should have memorized by now.. Air Resistance goes up 4X as the speed goes up 2X ..
