In cycling, cadence (or pedalling rate) is the number of revolutions of the crank per minute; roughly speaking, this is the rate at which a cyclist is pedalling/turning the pedals. Cadence is related to wheel speed, but is a distinct measurement.
Cyclists typically have a cadence at which they feel most comfortable, and on bicycles with many gears it is possible to maintain a preferred cadence at a wide range of speeds. Recreational and utility cyclists typically cycle around 60–80 rpm. According to cadence measurement of 7 professional cyclists during 3 week races they cycle about 90 rpm during flat and long (~190 km) group stages and individual time trials of ∼50 km. During ∼15 km uphill cycling on high mountain passes they cycle about 70 rpm.[1] Cyclists choose cadence to minimise muscular fatigue, and not metabolic demand, since oxygen consumption is lower at cadences 60-70 rpm.[2] When cycling at 260 W, a pedal force was the lowest at 90 rpm, lower than at 60, 75, 105 or 120 rpm. It is primarily due to increase of inertia of the crank with increasing cadence.[2]
Any particular cyclist has only a narrow range of preferred cadences, often smaller than the general ranges listed above. This in turn influences the number and range of gears which are appropriate for any particular cycling conditions.[3]
Certain cyclocomputers are able to measure cadence, and relay the reading to the cyclist via a display, typically mounted on the bicycle's handlebars.
