If we could, we would keep this suit a trade secret, giving our riders a competitive advantage. However, the UCI rules say that we must make such a product commercially available to maintain a level playing field for all. So here it is. We don't want to reveal too many secret details that make this suit so fast, but there are a few things you can see: the amazing fit in the time trial position, the smooth fabrics, the reduced number of seams and the long pants with flat elastic ends to keep them in place. The long sleeves have a loop on the thumbs that prevents them from hanging up. There's a window on the back where you can place your race number, wind-free - and unlike any other on the market, this window expands and breathes. We spent hundreds and hundreds of hours developing this piece. We do not say the exact number, because we did not even try to count it. We have access to testing facilities at the Norwegian University of Technology in Trondheim, where we addressed the detailed process of fabric selection and cut. This suit was made for WorldTour riders. It is optimized for speeds above 45 km/h and an extreme position during a time trial. At those speeds and with the right settings, it's the fastest suit we've ever tested and tried. Thank the UCI.
