The Free Aero RC Pro Bibshort is our top race short, which also means that it's insanely comfortable even if you never pin on a number. It's fair to say that we've been working on this short for the past 15 years. 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, San Remo, Roubaix, Liège, and Lombardia, 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. You feel Free because this is the first high-end short that doesn't 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 we've ever made. The Forza 2 fabric has 32% Lycra® with a high modulus for exceptional muscle support and just the right amount of compression. There's reflective piping on the back. And all logos are sublimation printed so they will never peel, crack, or fade. 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 Progetto X2 Air seamless seat pad is soft against the skin but well padded for long-distance comfort Minimalist bib straps allow maximum airflow, while a reinforced yoke keeps the straps flat over the shoulders Rear mesh pocket 5-panel construction for reduced seams and less chafing Sublimation-printed graphic and logos that will never peel, crack, or fade Reflective piping on back of legs Soft waistband with raw-cut edge panels for extra stretch and comfort Raw-cut leg ending engineered to stay put without silicone grippers 15°-35°C / 59°-95°F Weight:183g
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 performance tight with the right weight for most winter riding, with a focus on comfort, stretch, and protection. Nano Flex 3G fabric from waist to knee for soft warmth with maximum stretch and water repellency Nano Flex stretch woven fabric with brushed fleece inside at lower leg for splash protection on wet roads Stretchy bottom of leg with raw-cut edge means ankle zipper is not necessary Minimalist bib straps, as found on the Free Aero RC Bibshort, don't add extra bulk Rear pocket at bottom of bib straps Reflective tabs on back of legs Progetto X2 Air Seamless seat pad for long hours in the saddle. The Free Aero RC Bibtight is made to be your first choice for most of your winter riding. Everything about it is focused on keeping you comfortable and at the right temperature. Every detail, every fabric, every seam will make your winter riding better. This is the tight for those cool to cold days. Not for bitter cold, when you'll want to use a Sorpasso or Sorpasso Wind. Not for mild days, when you'll use leg warmers or a Semifreddo Bibtight. This is for maximum comfort on those days when you need warmth but you're not fighting for survival — those days when you're doing long rides getting ready for the season. Most of the tight is constructed from our Nano Flex 3G fabric. Our third generation of Nano Flex is luxuriously soft, warm, and stretchy. But it also offers excellent breathability, keeps a lot of the wind out, and has our updated Nano Flex water-repellent finish. The lower legs are in our lighter-weight Nano Flex stretch woven fabric with a lightly brushed inside and with leading water repellency. For the rest of the tight we've kept it simple: minimalist Free bib straps that you won't notice, and raw-cut leg endings that are stretchy enough to not need ankle zippers, improving comfort when you pull shoecovers over the top. This is supposed to be your long-ride comfort tight, so the Progetto X2 Air Seamless pad will be protecting your backside.
