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 skinsuit matters!
Air stall induces drag
One origin of aerodynamic drag is related to the fact that the air cannot follow exactly the shape of the objects, creating a stall in the airflow behind them.
The TT suit can mitigate air stall
One way to reduce this drag is to create a thin turbulent incident air layer, which can delay the stall phenomena. Engineering this thin turbulent layer is a real art TT suit designers try to master by placing small textures at certain strategic points.
The TT suit needs to fit the airflow around your body
The overall effectiveness of this technique depends on the rider’s body type, his position and his speed. How do you know which suit is right for you? There is only one answer: test it in real conditions!
« Endura Surface Silicone Topography – SST™ »
Example with real world data
On the left is an example of a TT suit benchmark we performed for one of our customers. The Endura SST appears to be far superior to the two other models. Unfortunately, the UCI now bans this model 🙁 Looking at the numbers, we can easily understand the reason: it’s simply too fast!
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.
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.
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.
