Road bike gear chart. Gear ratio s in the bike gear ratio chart are determined by dividing the number of teeth on the front chainring by the number of teeth on the rear cog. If your tire size is slightly smaller the speeds will be ever so slightly lower while the larger the tire the speed will be ever so slightly higher. A road bike s groupset or gruppo refers to any mechanical or electronic parts that are involved in braking changing gear or the running of the drivetrain. Too high tech for you.

The sram sachs 3 x 7 3 x 8 3 x 9 3 x 10 and the sturmey archer cs rf3 and cs rk3 are the only recent current production internal gear hubs designed to use rear sprocket clusters. Low temps and high winds will dictate a mountain bike to reduce wind chill and provide lower gearing for spinning to generate more internal heat. Road bike gear speed chart. The sturmey archer brompton bwr takes two sprockets but other models are included in the list for the benefit of tinkerers see discussion.
With these conditions on a road bike i take a helmet cover to reduce all the heat loss through a ventilated helmet. The following speeds are calculated using a wheel size of 700c and a tire diameter of 25mm.
