Bicycle Tire Low Rolling Resistance

The best road bike tires.

Bicycle tire low rolling resistance. Rolling resistance is the energy that is lost when the tire is rolling. Rolling resistance at 8 psi 0 6 bars single tire speed. 29 kmh 18 mph load. 29 kmh 18 mph load.

10 of the best clinchers tested at wheel energy on the. Tire rolling resistance on the road is caused by 1 internal friction and hysteresis deformation over time within the tire s materials and 2 on rough roads small bumps lifting the bike. 42 5 kg 94 lbs rr 120 psi 8 3 bar rolling resistance at 100 psi 6 9 bars. Tubolito inner tube tests.

42 5 kg 94 lbs rr 16 psi 1 1 bar rolling resistance at 20 psi 1 4 bars. While this approach worked moderately well in reducing friction using those tires felt like riding on rocks and they had very little grip. For many years narrow 23mm tires have been the standard width for road bike tires. However this has proved to be untrue.

In contrast to a car a cyclist has only very limited physical power which he wants to apply as efficiently as possible. 29 kmh 18 mph load. Gp 5000 endurance test. Best all round road bike tire.

The main reason for the loss of energy is the constant deformation of the tire. Tu tubular tire type price range buy at measured width on a 17 8 mm inner width rim at an air pressure of 100 psi 6 9 bars width weight rolling resistance at 120 psi 8 3 bars single tire speed. Because this is a rolling resistance test we examined both tubeless and clincher performance tires not more durable high wear models. 29 kmh 18 mph load.

Marathon 32 37 40 47 comparison. 42 5 kg 94 lbs rr 8 psi 0 6 bar rolling resistance at 12 psi 0 8 bars single tire speed. Tubeless sealant rolling resistance. Nowadays new tire compounds such as those based on silica and alternative.

Rolling resistance is the energy lost by the tires deforming as the wheels turn. Gp 5000 23 25 28 32 comparison. Tubeless vs latex vs butyl tubes. Each bicycle tire should of course roll as easily as possible.

42 5 kg 94 lbs rr 12 psi 0 8 bar rolling resistance at 16 psi 1 1 bars single tire speed. 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. Racers would go even narrower to 21mm with the general thought that the narrower the surface area the less rolling resistance. Originally low rolling resistance tires were made with a hard rubber compound and stiff sidewalls to reduce friction and flex.
