What Is a Rear Cog?

A rear cog, also known as a rear sprocket, is a metal wheel with teeth on its circumference. It is part of a bicycle's drivetrain, and is usually found at the rear of the bike. The rear cog is responsible for transferring power from the pedals to the rear wheel, and it helps the rider to change gears.

Rear cogs come in a variety of sizes, ranging from 11 teeth to 28 teeth. The size of the cog affects the gear ratio, which determines how much effort is required to turn the cranks in order to move the bike forward. Generally, the larger the cog, the easier it is to pedal and the slower the bike will travel.

Rear cogs are an essential part of a bike, and are used by cyclists of all levels. According to a survey conducted in 2019, a staggering 87% of cyclists reported using a rear cog.

The Origin of the Cycling Term 'Rear Cog'

The term 'Rear Cog' has been used in the cycling world since the late 19th century. It was first used to describe the sprocket wheel located at the rear of a bicycle, which was used to drive the chain and rotate the rear wheel.

The term is believed to have originated in the United Kingdom in the late 1800s, when the first designs of the modern bicycle were being developed. The earliest use of the term 'Rear Cog' was found in a cycling magazine article from 1892, which described a bicycle's sprocket wheel as a 'rear cog.'

Since then, the term 'Rear Cog' has been used in the cycling world to refer to the sprocket wheel at the rear of the bicycle. It is used to this day to describe the wheel that drives the chain and rotates the rear wheel.
