Road bike wheels: aerodynamic and rim height differences

Having good wheels is essential to ensure good performance, after all, it is the bicycle’s wheels that support the cyclist’s weight and transmit his power. In this article, we will explain the differences between the wheels, so you can choose the type that best suits your riding style.

There is a huge offer of different types of wheels available on the market, and sometimes choosing between them can be tricky, especially when you are not informed about the differences and benefits of each one.

The wheels of a bicycle are crucial elements, as they support the cyclist’s weight and transmit their power by being in contact with the ground. They are also responsible for braking, giving the tire traction, and allowing the cyclist to pedal on various types of terrain with minimal discomfort.

Types of road bike wheels

If you want to improve your performance, you must know the types of wheels that exist and which are the most suitable for your characteristics. Wheel types can be classified according to the size of their rims.

The size of the rims is important because, in addition to the aspects mentioned, such as the braking capacity, there are types of tires that can only be used in some widths.

There are basically three types of rims, and each width size has its specific advantages. Sizes must be evaluated according to the profile of each rider.

Low profile rims (shallow)

The height is up to 25 mm. They are the most used types of wheels, they are suitable for all types of bicycles and needs. They allow a considerable level of strength and a comfortable ride for the cyclist. These sizes are also used in high-performance mountain wheels, with less weight and less exposure to wind.

Intermediate profile rims (mid)

The height is between 25mm and 40mm. They have become increasingly popular due to the combination of the lightweight rim with some aerodynamic gains. They are light wheels for climbing and fast enough to make the roads flatter. I’d say they’re off-road models, quite versatile.

High profile rims (deep)

The height is over 40mm. It is the most suitable model for those looking for a lot of speed and training on flat terrain, as its aerodynamic construction is more geared towards that.

Before choosing the rim type, it is important that the cyclist asks himself where and how to ride so that the choice is the most suitable for his profile. Cyclists who are mainly looking for speed and who train primarily on uneven terrain can opt for the high-profile rim. For cyclists who are dedicated to terrain with large unevenness and are looking for light wheels, the intermediate rim is a good option. Cyclists looking for versatile rims for any type of need and bicycles can purchase low-profile rims.
