Castelli Free Aero RC ShortsDeveloped to give a brilliant sense of pedalling freedom, the Castelli Free Aero RC Shorts are their finest race shorts yet. You don't have to be a pro rider to enjoy the benefits the Free Aero RC Shorts offer. Whether riding for an hour or riding all day, the smooth, compressive support, premium seat pad and outstanding flexibility all offer unrivalled comfort. Less is MoreCastelli have deconstructed their previous Free shorts and started from scratch to deliver a more minimalist, but highly comfortable race short. Compared to previous iterations, there are fewer panels, now just 5 compared to 10. In combination with Castelli's high-stretch and compressive Forza 2 fabric, this gives a wonderful sense of freedom throughout your pedal stroke. Moving to the ends of the legs, this sees yet more minimalism. Instead of the usual elastic or silicone grippers, you'll find just smooth, raw cut edges. No more irritation when you're getting sweaty. After 28 prototypes and extensive material testing, Castelli have found the sweet spot, with shorts that remain in place but don't irritate or compress too much. At the waist the raw-cut edges offer a fabulously smooth and flexible fit, letting you breathe easily and yet maintain a perfect fit. Progetto X² Air Seat PadThe 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.

Castelli Free Aero RC Bib TightsAs you seek fitness gains during winter, building a strong aerobic base ready for spring and summer, you'll really appreciate the high-performance comfort, flexibility, water-repellence and warmth the Castelli Free Aero RC Bib Tights offer. The key to the success of the Free Aero RC Bib Tights is the use of two types of Castelli's own highly functional Nano flex materials. For most of the tights, Castelli deploys their Nano Flex 3G fabric. With a luxuriously soft fleece inside, you'll enjoy the utmost level of warmth as temperatures drop. It's flexible too, allowing for unrestricted pedalling while excellent breathability prevents you from getting too sweaty during high-intensity efforts. Not only that, but it also keeps most of the wind out and the nanotechnology water-repellent finish is just right to fend off drizzly rain. Meanwhile, lighter-weight Nano Flex stretch-woven fabric is used for the lower legs. A lightly brushed inner is warm but it's also good at regulating temperature to prevent overheating. As with the upper, a water-repellent finish prevents the chilly effect across the shins from spray thrown up from wet roads. 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 remove the need for zippers while still keeping a firm fit and working well with overshoes.Men's Progetto X² Air Seamless Seat PadThe 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.

Castelli Aero Race 6.0 JerseyIf you're a cyclist who loves the thrills of riding fast and testing your fitness in races, the aero-refined Castelli Aero Race 6.0 Jersey is just for you. A limited-edition design delivers fast style too. From Split Second to Aero 6.0The 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 FuelledOf 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.

Castelli Aero Race 6.0 JerseyWhat started as seeking small split-second advantages in racing has, in this sixth-generation Castelli Aero Race 6.0 Jersey, become an obsession with creating the most aerodynamic cycling jersey available - the advantages are now measured in whole seconds.Free Speed The name of Castelli's very first aero-focused cycling jersey was the Split Second. It caused quite a stir when it first appeared as until then performance cycle jerseys were about efficient moisture management with little consideration of progress through the air.
