Castelli Body Paint V TT Speed Suit Having access to the fastest riders in the world definitely has its benefits. And because of UCI rules to make race products commercially available, you, too, can access the same performance gains of the Castelli Body Paint V TT skinsuit. Developed through years of CFD analysis, wind tunnel testing, and WorldTour racing, this suit is purpose-built to deliver maximum efficiency when every watt matters. The advanced fabrics have been extensively tested for optimal aerodynamics at speeds of 45 km/h and above, helping you slice through the air with exceptional smoothness and stability. Every detail is refined for speed, from the reduced seaming that minimises drag to the no-sew mesh race number holder, which eliminates number flapping and keeps your profile perfectly clean. The extra-long legs with flat endings and PU grip elastic provide a secure, streamlined fit that stays perfectly in place throughout your effort. If you're chasing marginal gains in time trials or triathlons, the Castelli Body Paint V TT Speed Suit delivers podium-ready performance designed to help you ride faster than ever.
