During ≈15 km uphill cycling on high mountain passes they cycle about 70 r/min. [1] Cyclists choose cadence to minimise muscular fatigue, and not metabolic demand, since oxygen consumption is lower at cadences 60-70 r/min. [2] While fast cadence is also referred to as "spinning", slow cadence is referred to as "mashing" or "grinding".
From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
Cycling tends to feel more comfortable if nearly all gear changes have more or less the same percentage difference. [5] For example, a change from a 13-tooth sprocket to a 15-tooth sprocket (15.4%) feels very similar to a change from a 20-tooth sprocket to a 23-tooth sprocket (15%), even though the latter has a larger absolute difference.

Track sprinters make a compromise by using particular gear ratios that allow them to reach race speeds at a relatively high cadence (pedalling), around 130-135 revolutions per minute (r/min). [7] Long-distance attempts such as the hour record sometimes use high gear combinations such as 52×12 or 55×14.

The first fully mechanical digital computer, the Z1, operated at 1 Hz (cycle per second) clock frequency and the first electromechanical general purpose computer, the Z3, operated at a frequency of about 5–10 Hz. The first electronic general purpose computer, the ENIAC, used a 100 kHz clock in its cycling unit. As each instruction took 20 ...
