The concept for the Free Aero RC Bib Shorts is simple; use a premium seat pad, offer a refined fit with perfect muscle support and then remove everything else that’s not absolutely necessary. Whether you pin on a race number or not, the Free Aero RC are Castelli's most refined race short yet, with a fit and features that make them perfect for any cyclist. Less is More The focus of any cycling short is of course comfort, and here Castelli have taken a less is more approach. Compared to previous Free shorts there are now fewer panels, down from 10 to 5, and hence fewer seams. Highly supportive Forza 2 fabric is used to offer just the right amount of support and compression too. This all combines to give a brilliantly refined and sculpted fit, a wonderful sense of freedom during your pedal stroke and far less chance of chafing. This minimalist approach also extends to the leg grippers - or rather the lack of grippers. Instead, there are raw cut edges that feel fantastic. This has been made possible by extensive testing (28 prototypes), to get the fit and feel just right, and the support of compressive fabric. This gives an unrivalled sense of freedom and comfort that is unmatched. No more harsh elastic or irritating silicone. Refined Bib Straps When it comes to the upper body, again Castelli have sought to minimise the construction, removing bulk, boosting comfort and improving airflow. Open-weave bib straps let air in while also letting moisture evaporate away quickly. To the back, a reinforcing yoke ensures your straps remain flat and in place, while the mesh back is kept narrow, again to improve airflow to the body and prevent overheating. At the lower back, the bib forms a convenient storage pocket too. Progetto X² Air Seat Pad The top-end Progetto X2 Air Seatpad is now better than ever. Castelli has improved the shape of the back and improved the method of stitching it in place. The result is it now sits flatter and offers greater comfort. The X2 retains its awesome ventilating perforations, keeping you cooler and drier on endurance rides. The design allows air and moisture to flow directly to the surface fabric for quick evaporation maintaining dryness. A 3 layer component construction also features two densities of foam plus gel pads to provide progressive damping. A super-soft and stretchy next-to-skin layer, with an antibacterial finish, completes this premium pad.
From Split Second to Aero 6.0 The original Castelli aero jersey for road racing first saw light in 2006. It was known as the Split Second jersey. It was at a time when aerodynamics was only really considered important for time trials. Baggy cycling jerseys were the norm until that very first Castelli aero focused jersey appeared. However, with every new version of the jersey, the aerodynamic advantages have proved to be worth far more than just a few split seconds. It’s now known as the Aero Race 6.0 Cycling Jersey - designed to take your velocity up another notch. Using CFD (Computational Flow Dynamics) to analyse wake-flow, the Aero Race 6.0 will fit you even better when you're in an aggressive riding position while seam placement has been optimised to minimise drag. At speeds of between 30 and 55 km/h, the aerodynamic efficiency is optimised giving more speed without an increase of power output compared to a standard jersey. Same training. Same power. More speed. You could almost call it free speed. Cool and Fuelled Of course, riding fast, whether in training or racing, is going to generate heat. That, in turn, leads to sweat. However, the Aero Race 6.0 isn't just efficient through the air it's also efficient in dealing with moisture too. Quick wicking and with a 3D mesh back you'll be cooler and drier as you push hard on the pedals. To keep you up to speed and fully fuelled for your ride, the pockets are easily accessible when stuffed with gels and thanks to the drop tail design the jersey remains sleek even when they're loaded up. The Aero Race 6.0 Jersey is Castelli's most aerodynamically advanced design to date and yet it's also their best fitting too - Just ask their WorldTour professional riders. A remarkably comfortable high-performance cycling jersey whether it's your longest days in the saddle or a short and intense criterium race.

When it's time to build your aerobic base and slowly increase your winter miles despite the colder temperatures and frequent rain showers, you’ll want the superb warmth and comfort of the Free Aero RC Bib Tights to keep you company. The majority of the tights are composed of Castelli’s 3rd generation Nano Flex material. Nano Flex 3G is brushed-backed to offer luxurious warmth and with excellent stretch, it won’t restrict a fluid pedal stroke either. Not only that, but it’s also highly breathable to prevent cold sweat build-up and does a good job of blocking much of the wind. Lastly, it also features a nano-technology water-repellent finish, brushing off damp and drizzly weather conditions. To the lower part of the legs, you’ll find lighter Nano Flex stretch woven fabric. This is lightly brushed on the inside, trapping body heat. But excellent breathability prevents you from overheating. And it’s great at shrugging off spray from the road thanks to its nanotechnology water-repellent finish. Simplicity and functionality are key features of the rest of the tights. Minimalist bib straps will soon disappear from your mind while raw-cut ankle ends removes the need for zippers while still keeping a firm fit and working well with overshoes. Men’s Progetto X² Air Seamless Donna Seat Pad The pro-level Progetto X² Air Seamless seat pad utilises ventilating perforations to keep you cooler and drier on endurance road rides. The design allows air and moisture to flow directly to the surface fabric for quick evaporation maintaining dryness. The seat pad is constructed in 3-layer components, each dedicated to a specific purpose to create the most comfortable seat pad available.
