DERAILLEUR GEARS Meaning and
Definition
-
Derailleur gears are a type of bicycle gear system that allows for multiple gear ratios, enabling cyclists to adjust the resistance and speed of their pedaling. The system typically consists of a chain, multiple sprockets (gears) mounted on the rear wheel hub, and a derailleur mechanism controlled by the rider to shift between gears.
The derailleur itself is a movable arm mechanism, usually located on the rear wheel near the chain. It works by moving the chain from one sprocket to another when the rider operates the gear shifter. This process causes the chain to shift up or down the gears, thereby altering the gear ratio at which the cyclist is pedaling. By shifting into higher gears, the cyclist can achieve higher speeds with more resistance, while shifting into lower gears provides more ease and less resistance, ideal for climbing hills or riding on rough terrains.
Derailleur gears offer versatility and adaptability to changing road conditions and varying terrain. They allow riders to fine-tune their pedaling effort, optimizing their performance and reducing fatigue. The wide range of gear ratios afforded by derailleur gears makes them highly popular among road cyclists, mountain bikers, and recreational riders alike.
It is noteworthy to mention that derailleur gears require regular maintenance, such as cleaning and lubrication, to ensure their effective performance. Additionally, they may necessitate periodic adjustments to keep the shifting precise and responsive.
Etymology of DERAILLEUR GEARS
The word "derailleur" originates from the French language. The term "dérailleur" translates to "derailing" or "to derail". The word "gears" comes from the Old English word "gearwe", which means "equipment or clothing". Therefore, "derailleur gears" refers to the mechanism that causes the chain to switch between different gears on a bicycle.
