Rolling Resistance For Bicycle Tires

How tire rolling resistance affects cycling speed.

Rolling resistance for bicycle tires. Gp 5000 23 25 28 32 comparison. The energy needed for the constant deformation is then absorbed and turned into heat. We test bicycle tires on our rolling resistance test machine we puncture them on our puncture machine and we measure all dimensions with our micrometers. Bicycle rolling resistance is dedicated to providing the most detailed information about bicycle tires you can find.

As a tire rolls along the rubber and casing flex and unflex. Rolling resistance is a principle of physics and isn t specific to cycling. Tubeless sealant rolling resistance. Marathon 32 37 40 47 comparison.

Then to look at how much of a difference air pressure can make wheel energy took the best and worst performing tires and measured rolling resistance at 10psi increments from 70 to 120psi. Gp 5000 endurance test. Rolling resistance 60 psi 4 1 bar all numbers are for a single tireat a speed of 29 km h 18 mph and a load of 42 5 kg 94 lbs. Bicycle rolling resistance special articles.

When compared to the fastest tubeless road bike tires that are extremely thin and light the grand prix 5000 tl offers a much higher tread thickness and puncture resistance while rolling resistance is within 1 2 watts of the fastest tires. Rolling resistance is the energy lost by the tires deforming as the wheels turn. We started bicycle rolling resistance in 2014 because we re crazy about tires and the information we were searching for just didn t exist at that time. Tubolito inner tube tests.

Tubeless vs inner tubes. The best road bike tires. Rr watts crr speed m s load n to calculate rolling resistance at a given speed and load.
