I'd like to understand more about how the design of a bike affects its speed (assume a normal, two-wheeled bike with gears).
- Can I assume that weight has little effect, on level ground, except when starting and stopping? If not, why not: what is the effect and how big is it?
- Are the two biggest factors wind resistance, and tire rolling resistance?
Can you point me towards data for the above:
- Rolling resistances for various types/sizes of tire at different speeds
- Wind resistances for different rider positions at different speeds
Specifically how much difference is there between e.g. a 700x23 mm tire, and a 700x32 mm tire at 90 psi?
