Aero Meets Gravel: How Aerodynamics Can Transform Your Gravel Riding

While aerodynamics is a well-established factor in road cycling, it is often overlooked in the gravel world. However, optimising aerodynamics can make a significant difference in speed, efficiency, and overall performance on gravel terrain.

In this article, we explore why aerodynamics matter in gravel cycling, how tire width and wind resistance impact your ride, and what you can do to optimise your bike setup for maximum efficiency.

The Role of Aerodynamics and the Performance Impact of Tire Width and Wheel Setup
Most gravel cyclists prioritise comfort and traction – and rightly so. But if you want to ride faster and more efficiently, aerodynamics should not be ignored. Since rolling resistance increases on rough terrain compared to smooth asphalt, minimising drag can help offset some of these losses. This is especially relevant in gravel racing, where small improvements in efficiency can add up over long distances.

One of the biggest debates in gravel cycling is tire width. While wider tires offer better grip and comfort on rough terrain, they can also create more aerodynamic drag. Finding the right balance between width, pressure, and tread pattern is key to optimising both speed and handling.

Wind tunnel testing has demonstrated that wheels and tires significantly impact aerodynamics. A properly optimised wheel setup can reduce turbulence and improve airflow around the bike, resulting in a smoother and more efficient ride.

Another often overlooked factor is the advantage of group riding. Drafting behind other riders can significantly reduce wind resistance, allowing you to conserve energy and maintain higher speeds with less effort. This technique is widely used in road racing, but it can be just as beneficial in gravel events, especially on long, open sections with headwinds.

Can You Optimise a Gravel Bike for Road Use?

Some riders want the best of both worlds – a gravel bike that can perform well on the road. The good news is that with the right wheel and tire setup, you can make your gravel bike more aerodynamic for road riding. Swapping in a set of smooth, narrower tires can reduce rolling resistance and improve speed on paved surfaces.

Additionally, wearing aerodynamic clothing such as aero suits can also enhance performance by reducing wind drag.
