Gain Ratios - America's Bicycle Travel Experts
Calculate some gain ratios! Consider a road bike with 700 x 30 tires and 170 mm cranks. The diameter of the tires is approximately 680 mm, so the radius would be half that, or 340mm. To figure the radius ratio, divide 340mm by 170mm, yielding the answer of 2.0. Now, to calculate the gain ratio of the 53/19 gear we multiply the radius ratio by ... Retrieve Doc
