Rolling Resistance on Zwift: Crr and Watt Savings of Various Wheels
WebThe chart below assumes a fixed Crr of .00387, fixed speed of 20 mph and a standard 18 lb bike setup. By varying weight we can see the direct impact it has on the power needed to overcome rolling resistance friction. Now if we fix weight and speed and vary Crr from a very good tire value to a poor tire value we can see the impact from Crr changes. WebSep 4, 2024 · A tire’s Coefficient of Rolling Resistance (Crr) refers to the power cost of the tire (and inner tube, if used). This is typically measured on a smooth metal drum or roller, and tells us how much energy it takes for the tire to deform and return to shape on the roller as it spins, which generates heat. elizabethan superstitions
