Low Rolling Resistance Tires Bicycle

On the mountain bike it seems that the correlation between high cost low weight and low rolling resistance isn t so clear and when you take the leap to a fat bike that just goes out the window.

Low rolling resistance tires bicycle.

Rolling resistance is the energy that is lost when the tire is rolling. Racers would go even narrower to 21mm with the general thought that the narrower the surface area the less rolling resistance. I did climbing tests where the average speed was under 10mph 16kph and thus aero influence was low. Low rolling resistance tires are designed to reduce the energy loss as a tire rolls decreasing the required rolling effort and in the case of automotive applications improving vehicle fuel efficiency as approximately 5 15 of the fuel consumed by a typical gas car may be used to overcome rolling resistance.

The world s foremost expert on tire rolling resistance testing. Best all round road bike tire. Best road bike tires. In contrast to a car a cyclist has only very limited physical power which he wants to apply as efficiently as possible.

However this has proved to be untrue. The main reason for the loss of energy is the constant deformation of the tire. 42 5 kg 94 lbs rr 120 psi 8 3 bar rolling resistance at 100 psi 6 9 bars. There are a number of factors that contribute to rolling resistance.

Each bicycle tire should of course roll as easily as possible. So that s where independent testing comes in and no one currently seems to offer a more comprehensive list of tires with a repeatable test protocol than jarno bierman of bicycle rolling. 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. Rolling resistance is the energy lost by the tires deforming as the wheels turn.
