Your tires matter!

Your tires play a major role

Your tires are the only contact points between your bike and the road and are essential in the “low friction” race. Tires absorb road vibrations and maintain road grip thanks to their deformation.

But they cost you energy

This deformation is not free. It costs energy! This energy cost is characterized by the rolling coefficient Cr, which acts like a slight hill that you have to climb permanently (between 0.20 and 0.70% depending on the tire).

The each tire its rolling coefficient

All tires are not equal and can present very different rolling coefficients depending on the asphalt, the outside temperature and the pressures used. How do you know which tire is faster on a given terrain? The only answer: test it!

All tires are not equal : ground truth

Here are some tests carried out on tire candidates for a race with Aeroscale protocols. More than 16W* @45km/h separates the best and worst tires. Choosing your tires wisely can actually save you a lot of watts!!

*0.01% rolling resistance adds approximately 1W of resistance @45km/h for a 81kg rider (bike included)

Your tires matter!

After your helmet, your skinsuit and your position, one last – but not least! – parameter comes into play in the quest for the smallest fictions: your tires. Which tires for which rolling coefficient? This is what we are going to explain in this article.

Your position matters!

Can we go really faster on a bike without taking your position into account? Impossible! Let’s find out how your position influences the aerodynamic drag and why it needs to be tuned to optimize the aerodynamic coefficients.

Your skinsuit matters!

Did you know that even your skinsuit allows you to optimize your performance on a bike? This is 100% due to aerodynamic drag. The weaker it is, the faster you go. Let’s discover more about it.


Your helmet matters!

Choosing your helmet depends on multiple variables, including your morphology. In order to save your energy, it’s important to make the most efficient helmet choice to match your morphology. But first let’s try to understand why.
