Many false physics statements here guys...
203^2 is not the same as 350^2
First of all ---someone said smaller tires have more rolling resistance---you'd best come up with some real world testing to prove that.
Someone else said smaller wheels have less wind drag---show us the real world experiments.
700c tires are standard for racing because UCI requires it. Moultons used to race but were banned.
20" wheels allow groups to ride closer together which probably give significantly less wind resistance to the group (especially a small group like 3 people). I don't have proof.
Great arguments but feelings and theories need to be backed up by proof.
Other "known facts" that have been proven false recently--narrower tires are faster---higher tire pressure is faster---Higher thread count has less resistance---
So if you do not have actual proof---talk is cheap---But fun...
Anybody know why Prius wheels are so small?---less rolling resistance? Less mass to accelerate?
