CRANKARM Meaning and
Definition
-
A crankarm is a vital component of a bicycle's drivetrain system, which connects the crankset to the pedals. It serves as the lever arm that converts the downward force exerted on the pedals into rotational motion, propelling the bicycle forward. The crankarm typically consists of a long, tubular structure, often made of aluminum alloy, that extends from the bottom bracket spindle to the pedal axle.
The bottom bracket spindle, which rotates inside the bottom bracket shell, is attached to the crankarm at one end, while the pedal axle is connected at the other. This arrangement allows the rider to apply force on the pedals, causing the crankset and chainrings to rotate, transmitting power to the rear wheel.
Crankarms come in various lengths to accommodate different rider preferences and body sizes, ranging from around 165mm to 180mm. Longer crankarms provide increased leverage, ideal for riders seeking more power, while shorter ones emphasize faster cadence and often suit cyclists with shorter legs or those engaged in activities such as track racing.
Crankarms are typically designed with standard fittings, allowing compatibility with various bottom bracket types, such as square taper, external bearing, or press-fit. They may also have specific interface designs, like splined or hexagonal, which connect them firmly to the bottom bracket spindle.
Regular maintenance, including periodic cleaning and greasing, is essential to ensure smooth operation and longevity of crankarms. This entails removing the arms from the bottom bracket spindle using specialized tools, as well as inspecting for any signs of wear, damage, or play that may compromise performance and safety.

Etymology of CRANKARM
The word "crankarm" is a compound noun that consists of two parts: "crank" and "arm".
The term "crank" originates from the Old English word "cranca", which means "bend" or "hook". It initially referred to a device used to create rotary motion, particularly in machinery. Over time, its usage expanded to include the crankshaft - a component in engines and other mechanisms that converts reciprocating motion into rotational motion.
The word "arm" has a separate origin and comes from the Old English word "arm", which is derived from the Proto-Germanic word "armaz". It refers to the upper limb of the human body extending from the shoulder to the hand.
When combined, the term "crankarm" specifically refers to the component of a bicycle crankset that connects the pedal to the crank.
