What Are Deep-Section Wheels?

Deep-section wheels are a type of wheel that is used in cycling. The wheel is made up of a deep rim and a number of spokes, which hold the wheel together. The deep section of the wheel makes it more aerodynamic, allowing the cyclist to travel faster.

Deep-section wheels are most commonly used in racing and time trials. The aerodynamic advantages offered by the deep section wheels make them ideal for these types of events. According to research, deep-section wheels can provide a cyclist with a 5-10% reduction in drag, which can lead to improved performance.

Deep-section wheels are usually more expensive than standard wheels, due to the additional manufacturing processes involved in creating the deep rim. They are also more difficult to maintain, as the rim needs to be inspected more regularly for any damage.

Deep-section wheels are a popular choice for cyclists looking to improve their performance. While they come with a higher price tag, the aerodynamic benefits can be worth it for a competitive cyclist.


The Origin of the Cycling Term 'Deep-Section Wheels'

The term 'deep-section wheels', commonly used in the cycling world, first appeared in the early 1980s in Italy. The concept of deep-section wheels was first developed by Italian engineer Ugo De Rosa, who designed and built the first deep-section alloy wheel for professional cyclists. The design was based on the idea of creating a more aerodynamic wheel that would reduce drag and improve performance.

The introduction of deep-section wheels revolutionized the cycling world and soon became the standard for professional cyclists. By the mid-1980s, deep-section wheels were being used in professional races, and soon after, they were adopted by recreational cyclists. Today, deep-section wheels are the most popular type of wheel for cycling, and are used in a variety of disciplines, from road racing to mountain biking.

The term 'deep-section wheels' has become a ubiquitous term in the cycling world, used to describe any wheel that has a deep rim profile. The popularity of deep-section wheels is due to their aerodynamic advantages, as well as their ability to withstand higher speeds and more aggressive riding. Deep-section wheels are now the norm in the cycling world, and are an essential part of any cyclist's equipment.
