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. Features:Materials: 68% Polyamide, 32% ElastaneMesh: 77% Polyamide, 23% ElastaneHigh-compression 215 g Forza 2 fabric with 32% Lycra® content provides exceptional muscle support and compressionProgetto X² Air seamless seat pad is soft against the skin but well padded for long-distance comfortMinimalist bib straps allow maximum airflow, while a reinforced yoke keeps the straps flat over the shouldersRear mesh pocket5-panel construction for reduced seams and less chafingStitched scorpion logo patch and embossed Castelli wordmark for durabilityReflective piping on back of legsRaw-cut edge at waist for extra stretch and comfortRaw-cut leg ending engineered to stay put without siliconegrippersSuggested Temperature range: 15 to 35 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.

And with a matte finish, it also gives your shorts a premium look and feel.Across the thighs, raw-cut endings provide a smooth transition from shorts to the skin, while also reducing pressure and bulging. Inner silicone grippers are then used to hold the shorts firmly in place as you pedal. To the upper body, wide, flexible bib straps can be worn crisscrossed to the front or back, depending on what you find most comfortable. And with that high stretch, you can also take nature breaks without the need to remove the bibs.
