derailleur

 

[ dɪˈreɪljər ]

Noun
Context #1 | Noun

bicycle component

A derailleur is a mechanism on a bicycle that is used to adjust the chain's position on the gears, allowing for smoother shifting and better gear changes. It is typically located near the rear wheel and works in conjunction with the shifters operated by the rider. Derailleurs are essential for multi-speed bicycles, enabling a range of gearing options to accommodate different terrains. The word is derived from the French verb 'dérailler', meaning 'to derail'.

Synonyms

bicycle derailleur, gear changer, gear shifter.

Examples of usage

  • I need to adjust my derailleur before going on the ride.
  • The derailleur helps in shifting gears smoothly.
  • He replaced the old derailleur with a new one.
  • A well-tuned derailleur makes cycling more enjoyable.
  • She checked the derailleur for any misalignment.

Etymology

The term 'derailleur' derives from the French word 'dérailler', which means 'to derail' or 'to deviate from the track'. This explanation comes from the device's function in shifting the bicycle chain from one gear cog to another, effectively changing the bike's speed and performance. The use of derailleur systems became prominent in the late 19th and early 20th centuries, coinciding with the development of multi-speed bicycles. As cycling technology advanced and demand for versatile gear systems increased, manufacturers began to refine derailleur designs. The early types were simple and mechanical, whereas modern derailleurs are often made with lightweight materials and incorporate advanced engineering to allow for precise and quick shifts. The evolution of the derailleur is closely tied to the history of cycling itself, marking the transition from single-speed bikes to complex multi-gear systems that have become a standard in the cycling world.
