Better than ever before, even if you didn’t think that was possible, the Free Aero Race 4 Bibshorts from Castelli build on 12 years of extraordinary evolution to deliver exactly what you need on the road. The presence of the seamless Progetto X2 Air within the sumptuous chamois (detailed below) makes for a more comfortable and more freeing experience in the saddle than ever before, while the fourth generation of the legendary GIRO leg grippers hold on as tight as ever, but with the pressure spread over a wider area for a smooth and comfortable fit at all times.
Built for the pros, made for you
Castelli’s professional riders’ love for this bibshort is one of the worst-kept secrets in the industry, and that includes those riding for Team Sky. And as they hit over 30,000km every year between them, they’re the perfect play-testers, allowing the brand to make the necessary tweaks that make the Free Aero range so popular. As a result that are precisely zero compromises made when it comes to both speed and comfort, as shown by the aerodynamic and support Doppio V construction in the front.
Let's look at the Progetto X2 Air Seamless seat pad in more detail and see just why it's so incredibly comfortable. The first contact point against the skin, the upper skin-care material, is now seamless and even softer than previous versions letting you enjoy smooth and chafe-free pedalling. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it, thicker under the sit bones and thinner on the sides and under the perineum - the result is intense comfort with reduced bulk. Lastly, to really push home superior comfort levels, perforated viscous padding is added under the highly sensitive ischial and perineum pressure areas, offering luxurious support when you're on the saddle for hours on end.
