How can rolling resistance in bicycle wheels be reduced
Rolling resistance is a force that opposes the motion of a wheel rolling on a surface. It is caused by the deformation of the tire and the surface, and by the friction between the two. Rolling resistance is a major factor in determining the efficiency of a bicycle, and it can be reduced by a number of means.
One way to reduce rolling resistance is to use a tire with a lower coefficient of rolling resistance. This is a measure of how much force is required to roll the tire on a surface. Tires with a lower coefficient of rolling resistance will roll more easily and with less energy loss.
Another way to reduce rolling resistance is to use a wider tire. Wider tires distribute the weight of the bike and rider over a larger area, which reduces the pressure on the tire and the surface. This in turn reduces the deformation of the tire and the surface, and thus reduces rolling resistance.
Finally, rolling resistance can be reduced by using a wheel with a larger diameter. Larger wheels roll over obstacles more easily, which reduces the energy loss due to deformation of the tire and the surface.
By following these tips, you can reduce rolling resistance in your bicycle wheels and improve the efficiency of your bike.
