When Castelli engineered the first aero jersey for road racing back in 2006, everyone thought we were crazy. Back then, aero was only for TTs. Performance clothing meant moisture management. And you could win the Tour de France with a baggy jersey that was little more than a polyester T-shirt. Even our aerodynamic consultants expected limited gains, so we named the jersey Split Second, though, like now, we thought even small gains were worth pursuing. In the end the gains were pretty substantial, and we completely revolutionized the look of the pro peloton. We're now on the sixth major revision of our aero jersey. Each generation has become more aero and better fitting. The Aero Race 6.0 benefits heavily from CFD analysis of wake flow in the riding position for fabric and seam placement. It also benefits from pro riders' feedback, as we've worked to make the jersey comfortable for their long hours of training and then racing in every possible weather condition. CFD-based fabric placement and seam construction Engineered for aero efficiency at 30 to 55 km/h Airflow shoulder construction Velocity Rev2 fabric on front and sleeve 3D mesh back for breathability Elbow-length stretch sleeves with raw-cut edge YKK® Vislon® zipper Drop tail allows perfect pocket placement while keeping jersey fitting well at waist 18-35°C / 64-95°F Weight: 109 g

The Free Aero RC W Short is our top race short, which also means that its insanely comfortable even if you never pin on a number. Its fair to say that weve been working on this short for the past 15 years. Thats how long its been since the original Free Aero Race Bibshort was first introduced, initially as our top-of-the-line race short. The various versions of the Free have dressed all our pro womens teams over this time, and it also became the best-selling womens short in the history of Castelli because, simply put, this is the short that does everything well. The concept is quite simple: start with the best pad we know how to make, surround it with a supportive short with good muscle compression, and then remove everything else thats not absolutely necessary. |You feel Free thanks to the reduced number of panels and the reduced number of seams. In fact, the short has just 5 panels compared to 10 in the previous generation. You feel Free because of further refinements to the Progetto X2 Air Donna seamless seat pad. The two densities of foam plus the gel pads provide progressive damping, while the separate Skin Care Layer is soft and stretchy to move with your skin. You feel Free because this is the first high-end short that doesnt need any sort of gripper or elastic at the end of the leg to keep the leg in place. Getting this right meant 28 prototypes and our most extensive test program ever, and it results in the most comfortable leg ending weve ever made. The Forza 2 fabric has 32% Lycra® with a high modulus for exceptional muscle support and just the right amount of compression. Theres reflective piping on the back. And all logos are either stitched or embossed for durability. What It Is The perfect mix of comfort and speed. Engineered for top-level racing, which also makes it supremely comfortable for every ride and rider. Product Features High-compression 215 g Forza 2 fabric with 32% Lycra® content provides exceptional muscle support and compression Women’s-specific Progetto X2 Air Donna seamless seat pad is soft against the skin but well padded for long-distance comfort 5-panel construction for reduced seams and less chafing Stitched scorpion logo patch and embossed Castelli wordmark for durability Reflective piping on back of legs Raw-cut edge at waist for extra stretch and comfort Raw-cut leg ending engineered to stay put without silicone grippers 15°-35°C / 59°-95°F
The Free Aero Race Cap isnt really aero, but it matches performance to the Free Aero RC Bibshort. This cap keeps the wind off like a traditional cotton cycling cap, but it wicks moisture much better and doesnt wet out like a cotton cap. The perfect blend of a traditional look with modern fabrics. Product Features Traditional cycling-cap cut Woven polyester twill fabric keeps wind off but stays dry Sublimated graphic doesnt fade or wash out

That's how long it's been since the original Free Aero Race Bibshort was first introduced, initially as our top-of-the-line race short. Since then it has won three Tours de France, three Giri d'Italia, one Vuelta and San Remo, but it also became the best-selling product in the history of Castelli because, simply put, this is the short that does everything well. The concept is quite simple: start with the best pad we know how to make, surround it with a supportive short with good muscle compression, and then remove everything else that's not absolutely necessary. You feel Free thanks to the reduced number of panels and the reduced number of seams. In fact, the short portion has just 5 panels compared to 10 in the previous generation. You feel Free because of further refinements to the Progetto X2 Air seamless seat pad. The two densities of foam plus the gel pads provide progressive damping, while the separate Skin Care Layer is soft and stretchy to move with your skin. You feel Free thanks to the most minimal bibs you've ever seen in a short, including open-weave straps for maximum airflow. But we reinforced the yoke so the straps stay in place and made the mesh back narrow for coverage that is minimal yet just enough to hold the shorts in place. And the bib elegantly frames a convenient pocket at the center back.
