Le Col Pro Long Sleeve JerseyThe Col Pro Long Sleeve Jersey is the bridge between your summer and winter kit. Aero like a summer jersey but warm like a winter jersey it's also highly breathable for impeccable comfort come spring and autumn. Autumn and spring are brilliant seasons to ride but getting your cycling kit right can be tricky - too mild for a winter jacket but not quite warm enough for summer jersey and arm warmers. It's here the Pro Long Sleeve Cycling Jersey comes into its own. Made from a 4-way stretch brushed back Lycra it's got a touch of extra thickness to prevent cold seeping in and hold onto body heat but you'll still enjoy that close aero fit and breathability of a summer jersey - ideal for steady autumn rides or for those early season interval efforts. The 'Pro-Fit' is lightly compressive, offering efficient aerodynamics but also ample freedom of movement when you're jumping in and out of the saddle. A low-stack ergonomic collar is brilliantly comfortable while low profile cuffs and a silicone hem band keeps the fit sleek when you're in a riding position. Finished with three rear pockets and a concealed fourth waterproof, your valuables are secure on the road.Features:Material: 77% Polyamide, 23% ElastaneTextured brushed back Force lycra with four-way stretchLightweight 120 gsm fabric weightBreathable material with moisture management propertiesSPF50+Pro compressive fit with silicone band at the hemThree rear pocketsFourth Waterproof pocketLow profile cuffsCoverstitched for strength and securityEmbroidered logosBuy Le Col Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.

Castelli Gabba ROS 2 JerseyThe Castelli Gabba ROS 2 Jersey continues to lead the pack in all-around cycling performance. This 5th generation is now more water-resistant than ever while offering excellent breathability, improving upon its already outstanding comfort come rain or shine. The Gabba made its revolutionary debut back in 2010. And ever since then its been the benchmark by which all-around cycling performance is judged. The Gabba ROS 2 Jersey excels in the cold and wet, keeping you warmer and drier. But in dry and milder conditions, excellent breathability ensures brilliant comfort too. The incredible versatility has been achieved thanks to the use of two Castelli exclusive Gore-Tex INFINIUM™ WINDSTOPPER® fabrics. Gore-tex INFINIUM™ WINDSTOPPER® 205 is deployed across the front, sleeves and shoulders. This faces into the weather and offers complete wind protection, a high degree of water resistance and a brushed inner face to hold in warmth. Across the back of the jersey, meanwhile, lighter and high-stretch INFINIUM™ WINDSTOPPER® 203 gives a snug fit and outstanding breathability. When there's an injection of pace or a rise in temperatures, this ensures you don't overheat and get a chill from cold sweat. It’s water-repellent too, fending off road spray.Compared to the previous iteration the Gabba ROS 2 gets some key detail improvements. In order to improve control of ventilation, the KK® Vislon® front zipper is now two-way. This lets you introduce airflow to either the top or bottom of your body. For low-light cycling, the reflectivity is now more visible and pockets to the back now hold more gear. Lastly, seams at the shoulders have been moved to the back, reducing exposure to wind and rain. The Gabba RoS 2 is a must-have for autumn and spring riding when weather conditions can change in an instant.Features:Materials: 100% PolyesterCastelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water-resistant fabric on front-facing surfacesGORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch on rear-facing surfaces for greater stretch and breathabilityTaped shoulder seams for extra rain protectionTop- and bottom-opening YKK® Vislon® zipper for easy sliding, covered for additional wind and rain protection3 rear pocketsReflective panel at bottom of pocketsWeight: 245gSuggested Temperature range: 9 to 16 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.

Castelli Premio Black Cycling Bib ShortsThe finest Castelli shorts yet made, the Premio Black Cycling Bib Shorts are a marvel of fabric engineering, with an exceptional fit and premium seat pad that all combine to deliver luxurious cycling comfort.Seamless PerformanceLess is more when it comes to the Premio Black Cycling Bib Shorts. The construction uses fewer seams and fewer panels and yet comfort, fit and flexibility is outstanding. And this is all made possible thanks to the innovative engineered fabric. With no need to stitch panels together, comfort is enhanced and gives the shorts a sleek, sophisticated look.Gradient StretchStarting at the pelvis, the engineered material offers a high degree of compression and muscle support. This thicker fabric also avoids any transparency issues. As you move down the shorts you'll find the material gradually becomes lighter. This ensures exceptional flexibility when pedalling and a boost to moisture management as you raise the pace or temperatures rise. The four-way stretch also provides just the right amount of muscle support too. Meanwhile, raw cut endings and rubberised yarns keep the legs in place.Moving to the upper body, the premium fabrics offer a smooth and comfortable fit with straps securing the shorts without cutting into your shoulders. A perforated back regulates body temperature while bonded edges make sure you don’t notice the thickness of a stitched edge.Progetto X2 Air Seat PadInside the shorts, you’ll find Castelli’s premier Progetto X2 Air seat pad. This exceptional seat pad has an incredibly soft and seamless upper face material, delivering superb comfort. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it, thicker under the sit bones and thinner on the sides and under the perineum. The results are intense comfort with reduced bulk.Features:Materials: 65% Polyamide, 34% Elastane, 1% PolyesterGradient stretch woven fabric for the right support in the right placeWoven fabric weighs 30% less than comparable knit fabricPerforated back bib panel with lie-flat bib straps that don't bind at shouldersIntegrated gripper elastic at leg ending holds short in place without need for extra silicone grippersLaser-etched logos with RossoCorsa at center back and black scorpion shadow logos at lower legsProgetto X2 Air Seamless seat padSuggested temperature range: 14 to 38 Degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
Castelli Free Aero RC Bib ShortsFirst launched 15 years ago, and worn to countless victories, the Free shorts are legendary for their comfort. The Castelli Free Aero RC Bib Shorts build on this heritage, making them the best racing shorts Castelli have ever made. You don't have to be a pro rider to enjoy the benefits the Free Aero RC Bib 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. 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 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 Unlimited Trail Baggy ShortsHighly flexible but extremely durable, the Castelli Unlimited Trail Baggy Shorts are ideally suited to the demands of cycling off the beaten track. A pair of shorts for adventurous cyclists. The first thing to notice when wearing the Unlimited Trail Baggy Shorts is how light they are. At just 165 grams per square meter, the material used for the shorts ensures you'll barely notice you have them on. The material also features Cordura® yarns, offering excellent abrasion resistance for off-road cycling. And then there's the stretch of elastane. This allows you to move and react to the terrain as well as pedal smoothly, all without ever feeling restricted. For days that are misty and drizzly, a DWR (Durable Water Repellent) finish makes sure water rolls off rather than soaks into your shorts. They're quick-drying too, ensuring comfort in changeable riding conditions. If the sun comes out and you're feeling hot, zippered ventilation openings that run the full length of the legs allow cool air to flow. Castelli cut the shorts with a loose fit, again to aid in easy movement, yet the adjustable webbing waist belt ensures there's no annoying slippage when riding.Features:Materials: 90% Polyamide, 10% Elastane165 g 4-way-stretch woven Cordura® fabric with DWR (Durable Water Repellent) finishDouble-slider zippered ventilation along full length of legsExtremely light so you won't even feel it on2 front pocketsAdjustable webbing belt for a secure fit at waist, with zippered front openingScorpion button logoLooser fit at home on any trailBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
