All rolling resistance rr figures shown below are for a 50kg load on the rough surface drum.

Bicycle rolling resistance calculator. We calculate rolling resistance as the nominal crr for the surface multiplied by the ratio of one tire to another. 2020 08 28 jarno bierman. Rolling resistance will be reduced and the bike will run smoothly with plenty of propulsion. Rolling resistance at 100 psi 6 9 bars single tire speed.

The force resisting the motion of the bicycle f total consists of the sum of rolling friction f roll aerodynamic drag f wind the force needed to accelerate f accel the upward slope resistance f slope bearing friction resistance and loss due to the drivetrain efficiency factor η greek letter eta. Just curiosity as i frequently bike the same route and wanted to see how much i was burning. 29 kmh 18 mph load. We picked the tire with the lowest rolling resistance premium clincher as a standard to which the other tires are compared.

42 5 kg 94 lbs rr 60. Rolling resistance is figured by multiplying weight by a number that gives the force the coefficient of rolling resistance. The clinchers used an 88g butyl tube and the tubeless tires had 25ml of sealant which adds about 25g. 29 kmh 18 mph load.

Every tyre has cushioning properties which come more or less to the fore depending on tyre pressure. Pirelli p zero velo race tlr review. 29 kmh 18 mph load. Bike calculator welcome to the oldest and most popular bicycle performance prediction calculator on the web since 1997.
