Road Bike Gear Ratio

road bike gear ratio
    gear ratio
  • (in a gearbox, transmission, etc.) The ratio between the rates at which the last and first gears rotate
  • Number, usually expressed as a decimal fraction, representing how many turns of the input shaft cause exactly one revolution of the output shaft. Applies to transmissions, power takeoffs, power dividers and rear axles. Example: If 2.
  • The gear ratio is the relationship between the numbers of teeth on two gears that are meshed or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt.
  • This is used to compare gearing. For example, on a road bike with 18 gears, there are 2 chainrings and 9 cogs. To check the gearing, count the teeth on the cogs and chainrings and create a chart with the rings on top and the cogs on the side.
    road bike
  • A bicycle that is suitable for use on ordinary roads, as opposed to a mountain bike
  • A road bicycle is similar to a racing bicycle. However, road bikes are built more for endurance and less for fast bursts of speed, which is desired in a racing bicycle. They usually have more gear combinations and fewer hi-tech racing features.
  • A bike with narrow tires best suited for paved roads. Usually noted by drop style bars.
  • A motorcycle that meets the legal requirements for use on ordinary roads
  • (Road biking) Road cycling is the most widespread form of cycling. It takes place primarily on paved surfaces. It includes recreational, racing, and utility cycling.
