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
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. A remarkably comfortable high-performance cycling jersey whether it's your longest days in the saddle or a short and intense criterium race.Features:Materials: 82% Polyester, 18% ElastaneCFD-based fabric placement and seam constructionEngineered for aero efficiency at 30 to 55 km/hAirflow shoulder constructionVelocity Rev2 fabric on front and sleeve3D mesh back for breathabilityElbow-length stretch sleeves with raw-cut edgeYKK® Vislon® zipperDrop tail allows perfect pocket placement while keeping jersey fitting well at the waistWeight: 109gSuggested Temperature range: 18 to 35 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
Castelli Alpha ROS 2 JacketPart of their Rain or Shine range, the Castelli Alpha ROS 2 Jacket is an adaptable and protective cycling jacket suited to a wide range of weather conditions. Great in the cold and dry weather, protective in warmer and wetter weather, it lives up to the Rain or Shine moniker. This third generation of the Alpha ROS 2 Jacket is the best yet. Updates include improved fabrics to give a boost to performance in the wet as well as enhancing breathability while new double-layer cuffs work better with winter gloves. And it still retains the innovative double-layer construction that makes it so good in so many cycling conditions. Rain Out. Warmth in. Dressing for changeable weather is always tricky. Too warm. Not warm enough. Lots of layers. Rain jacket. It's all a bit much sometimes. However, the Alpha ROS 2 is best in class for your cold, dry days on the bike. And yet come rainy weather, you won't have to immediately reach for a hardshell rain jacket. This is all made possible by the high-performance Gore® INFINIUM™ Windstopper® 150 fabric and double-layer Alpha construction. Gore® INFINIUM™ Windstopper® 150 fabric is completely windproof, superbly breathable and fends off all but the heaviest of downpours. Meanwhile, the Alpha design keeps the outer weather-protective layer from the inner insulating layer. This allows you to keep your core protected while still ventilating the outer layers. The result is more control of body heat, better moisture evaporation and greater comfort across a wide range of conditions. Performance Fit and FeaturesStretch fabrics with advanced patterning make for an excellent close-to-body fit that still accommodates a wide range of body types. A raw-edge waist that lies flat and moves with you plus the Castelli silicone text gripper at your waist keeps the jacket from riding up. 3 rear pockets with reflective laser-cut drain holes plus an extra pocket with waterproof zip make for a very practical jacket with plenty of storage space.For those of you seeking the ultimate in versatile all-weather, multi-season cycling protection you really need not look any further. Think of this as taking all your winter kit options and distilling it into one incredible do-it-all garment. We think you'll find it's worth every penny.Features:Materials: 100% PolyesterGORE-TEX INFINIUM™ WINDSTOPPER® 150 fabric for wind protection, high breathability and effective rain protectionReduced seaming with seam sealing on shouldersDouble-layer Alpha construction separates the insulating layer from wind/water barrierRaw-edge waist with silicone gripperDouble-layer cuff integrates with glovesBack ventilation3 rear pockets with reflective laser-cut drain holes + zippered secure side pocket for valuablesWater-resistant YKK® Vislon®Stretch fabrics with advanced patterning make for excellent close-to-body fitSuggested temperature range: -5 to 10 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
