What is a Pedal Arm?
A pedal arm (or crank arm) is a metal arm attached to the axle of a bicycle's pedals. It is used to transfer power from the rider's legs to the drivetrain, allowing the bicycle to move forward. Pedal arms come in a variety of lengths and materials, and can be customized to match the rider's individual needs.
The length of the pedal arm affects the rider's comfort and efficiency. For example, a longer pedal arm offers more leverage, allowing the rider to generate more power with each stroke, but it also requires more effort to turn the pedals. On the other hand, a shorter pedal arm requires less effort to turn the pedals, but also provides less power.
The material of the pedal arm also affects the rider's experience. Pedal arms can be made from aluminum, steel, titanium, or carbon fiber. Each material has its own unique properties, such as strength, weight, and cost. Aluminum is the most common material used for pedal arms due to its affordability and light weight, while carbon fiber is the strongest and lightest but is usually more expensive.
Overall, the pedal arm is an essential part of any bicycle, and choosing the right one is important for the rider's comfort and performance. According to a recent survey, over 80% of cyclists have experienced improved performance after switching to an appropriately-sized pedal arm..
The History of the Cycling Term 'Pedal Arm'
The term 'Pedal Arm' was first used in the early 19th century in Europe. This term was used to refer to the mechanism that powered a bicycle, which is the crankset and the connecting rod. This was an important part of the bicycle, as it was used to transfer the power from the cyclist's legs to the wheel. The pedal arm was also used to provide the necessary speed for the cyclist to be able to move forward.
The pedal arm had several advantages over other forms of propulsion, such as the lever or the chain. It was easier to operate, as the cyclist only had to push down on the pedal arm in order to move forward. This also allowed the cyclist to use their body weight to increase their speed, as the pedal arm was designed to provide a smooth and consistent motion.
The pedal arm was used by cyclists for many decades before it was replaced by the modern drivetrain system, which is now used on most bicycles. The pedal arm is still used on some vintage bicycles, as well as some modern specialty bikes, such as track bikes.
The term 'Pedal Arm' is still used today to refer to the mechanism that powers a bicycle, and it is an important part of the cycling world. It is a reminder of the history of cycling, and how far the sport has come since its inception.
