Rolling resistance is the energy that is lost when the tire is rolling. Pushing a road bike at 40 kilometers per hour on a flat road demands power output in the range of 270 350 watts for most cyclists. Each bicycle tire should of course roll as easily as possible. Best road bike tires.

Rolling resistance is the energy lost by the tires deforming as the wheels turn. Gp 5000 23 25 28 32 comparison. Two tires with a rolling resistance of 50 watts each will. Here s our guide to road bike tyre pressure.

In contrast to a car a cyclist has only very limited physical power which he wants to apply as efficiently as possible. With so much research data pointing to the positive impact on both rolling resistance and comfort of lowering pressures we think it s time all. On smooth surfaces like the one used in the tests shown above moderately high tire pressure say 100 110 psi for a 25 mm tire actually rolls slower than either a lower pressure 80 psi or a higher pressure 130 psi. Wheel energy tested 10 tires on a smooth drum and then again on a rough surface.

Despite rolling resistance only accounting for about 10 of the total resistance experienced by a typical ultra distance cyclist over an entire race different tire choices can make a significant impact on average cycling speed. Tubeless sealant rolling resistance.
