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.
In 2016 we started our aero research project with the Norwegian Technical University in Trondheim. Besides having a couple of brilliant professors and PhD students to come up with ideas and do the basic research, they have a couple of wind tunnels, rapid prototyping capabilities, CFD analysis and a true desire to make fast stuff. The first big success from the research was Team Sky's TT suit that placed four riders in the top eight at the opening Tour de France time trial. Then the UCI made it illegal. So this suit isn't UCI legal (but neither is your bike). It's faster than the pro cyclists' suits and very illegal due to the silicone ribs in the arms. The main body fabric is an impossibly light 50 denier — usually in sports clothing 40 denier is considered ultrafine. The legs and sleeves are long for aerodynamics, while the light fabrics are great for dealing with heat since they're thin enough to not get weighed down, yet the 8% Lycra® content holds a bit of moisture next to your skin for rapid cooling. The insane stretch allows us to make something that truly fits like a second skin on the bike but that doesn't restrict in any way on the swim or run. The PR Speed Suit KISS Tri pad offers some welcome padding while you're on the bike but is thin enough to not bother you on the run. This suit offers real time savings on the bike leg while providing cooling and comfort on the run, but it was made with the expectation of being worn under a swimskin or wetsuit for the swim. It's optimized for high speeds — top age groupers or pro athletes, or anyone looking to set a new PR.

Socks are an often-overlooked part of a cyclist's kit. But great socks make a huge difference to your on-the-bike comfort, and they don't come much better than the Endurance 15 Cycling Socks. All-day pedalling comfort all starts with their 200-needle construction. This super-fine construction method gives a snug and luxurious fit, while also giving excellent strength. The Bioceramic yarns are also impressively quick to draw away sweat while also combatting the build-up of smell-causing bacteria. Castelli have added some cushioning on the underside of the socks, easing pressure points where you press down on the pedals. Reinforced toe and heel zones add durability, and a midfoot band gives support and prevents slipping.
Castelli are renowned for pushing boundaries when it comes to cycling performance. And the Entrata VI Short Sleeve Jersey benefits from this extensive R&D, engineered with the same attention to detail as their top-end jerseys. This can be seen in the one-piece sleeves, with aero-optimized seaming, keeping you streamlined as speeds rise. Raw-cut sleeve endings also fit brilliantly, without constricting. Four-way stretch Air Mesh fabric gives a snug but comfortable fit. And it’s lightweight too, perfect for warm summer days on the bike. Castelli also adds their ProSecco treatment, ensuring sweat is dealt with quickly and efficiently. UPF 30 sun protection, filtering 97% of UV rays, also keeps you more comfortable under summer skies. Details are thoughtfully applied too. A full-length YKK® Vislon® zipper is easy to slide, a stretch panel in the centre pocket allows extra carrying space and a silicone gripper keeps the back of the jersey in place. As the sun sets, a reflective insert on the pocket keeps you more visible as you pedal homewards.
Heat. Altitude. No Problem. The design of the Climber's 3.0 SL Cycling Jersey was a direct result of the needs of pro riders needing a jersey for racing in the high mountains and heat of summer races. While few of us regularly experience the rigours of racing those soaring peaks and hot mountain passes, the products created off the back of them benefit us all. The first thing to note is the weight or rather lack of it. A size large comes in at a featherweight 106 grams and the open fabrics ensure as much cooling airflow as possible, at both low and high speeds. Quick-drying fabrics prevent discomfort from sweat build-up and has the advantage of preventing you from feeling the chill from cold sweat windchill when plunging down the descents. Even on damp days, it doesn’t soak up moisture, so much so the pros often use this jersey even when it’s wet. Ready to Race The fit is also very much race-focused. In fact, the patterning is taken from the super-smooth Aero Race Jersey, delivering aerodynamically efficient performance alongside its lack of weight. Elbow-length sleeves, with raw-cut edges, and airflow shoulders both reduce drag too. And for bright sunny days on the bike, the back blocks more than 90% of UV rays. Even if you’re not racing or tackling the searing heat and steep slopes of the Alps this summer, you’ll still love and benefit from how cool, streamlined and light this jersey is. Light. Dry. Fast. Bring on summer cycling.
While the Unlimited Ultimate Liner Bib Shorts may be hidden under baggy shorts, Castelli have still applied the exact same level of performance and detail as for their race shorts. At the heart of the shorts is their renowned Progetto X² Air seamless seat pad. With dual-density foam and gel pads providing support and damping, it's as good for rough trails as it is for smooth roads. Thanks to a carefully designed hip area, using compressive Force fabric, as you move, manoeuvre and pedal, the pad remains firmly in place, preventing chafing. Seeing as these bibs are to be used under baggies, the legs are kept light and airy to maintain comfort. Perforated fabrics and the gauze-like GIRO Air elastic grippers allow for cooling airflow and for your skin to breathe. Meanwhile the upper is also minimalist in design. Open-knit bib straps let the air flow about the body easily while the back is kept narrow to reduce coverage. A back yoke keeps the straps in the right place and prevents bunching. The final flourish is the inclusion of 3 storage pockets. These can be found to the back, sitting just above the waist height of your baggy shorts. An ideal place to stash essentials when you're wearing a loose-fitting t-shirt/cycling jersey.
The Giro105 Competizione Jersey can boast both fabulous performance and excellent eco-credentials thanks to the use of recycled materials from fabric experts Sitip.

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.
A completely new approach for sprint and short distance racing the Castelli Women's SD Team Race Tri Suit has been developed in close collaboration with the German Triathlon Federation (DTU) with aims to design a suit that's ready for any battle on the ITU (International Triathlon Union) circuit. In ITU racing you can't afford to lose valuable seconds in the water due to bad equipment. Therefore high-performance fabrics and optimised patterning for best aerodynamics and comfort on the bike till the finish line offer everything you'd expect from a suit that has to prove suitability on the highest level of pro racing.
Fit for the Pros The Giro105 Race Jersey is the exact jersey the pros will wear in the Giro d'Italia, the only difference being the leaders get their team graphics on the front. Be it a hard training session or a sunny social ride for coffee this is a jersey that looks and feels the part. Fabulous Fabrics Comfort and performance come via the use of highly functional fabrics. Giro Aero fabric is used across the front of the jersey, engineered to be extremely smooth to reduce drag while also being quick to wick away sweat. Across the back, Giro Infinito fabric is deployed to offer excellent moisture management. When you're putting in race-pace efforts this will ensure you don't end up drenched in sweat - ideal for rides that see frequent changes in speed and intensity, just like a Giro stage. Made for Speed As you'd expect of a jersey designed for professionals, the fit is kept close to the body to ensure smooth aerodynamics. In fact, the fit is based upon the smooth and streamlined Aero 6.1 Race jersey. At speeds of between 30 and 55 km/h, the aerodynamic efficiency is optimised giving more speed without an increase in power output compared to a standard jersey. Same training. Same power. More speed. Winning Details Attention to detail is demonstrated by the mesh number pockets. Not only removing the need for pinning of numbers they also keep everything smooth and streamlined when racing. The drop pockets hold plenty of gear while resisting sagging and a gold finish 'Trofeo Senza Fine' zipper and jacquard woven Prodotto Ufficiale label finishes the jersey in perfect Giro style.
Stage 16 - The Mortirolo Stage The Mortirolo, a fearsome climb that has made and broken many a professional and amateur cyclist.

Let's start in reverse order: Run: At this point in the race, fatigue sets in. You'll love the comfort of this suit. The front Samremo opening construction doesn't pull you forward, and it makes pee stops easier and lets you open it up when you feel too hot. The fabrics are quick drying, light and cool. The seat pad that felt so good on the bike is small enough you hardly feel it. The two rear pockets compress your gels so they don't bounce around. The long legs with Giro4 leg gripper elastic don't ride up and don't bind. Maybe you'll even notice that you don't have as many burning spots where you've been chafed raw. Somehow, you're thinking that comfort gives you an extra push, some extra speed. Bike: You relish these couple of hours to put some distance into the other guys. This suit benefits from the aero research of Castelli's Pro PR suit but is tuned for speeds ranging from medium to high. The legs and sleeves provide excellent coverage while the back gives decent sun protection and the two pockets hold plenty of nutrition. And you appreciate the Castelli know-how in seat pad construction. Put your head down and pass a few more riders. Swim: The reduced seaming and long arms and legs help you cut through the water while the pockets lie flat and don't catch water. The fit is snug and the lightweight fabrics don't hold as much water. The shoulder area is extra stretchy for freedom of movement even under a wetsuit or swimskin.
Castelli Special Collection With the promise of warmer weather, longer days and more opportunity to get out and ride, we're very happy to bring you a fabulous range of Special Collection cycling kit and accessories. They're the ideal choice to keep you comfortable and stylish on your bike. Sock Perfection You may not give much thought to your socks when you're cycling, but you'll soon notice a bad pair. Not so the Gara Socks from Castelli, these are so comfortable you'll barely notice they're there. Made from Meryl Skinlife® yarns, they're quick to pull moisture away from the skin for superb comfort. And in combination with the antibacterial silver ions, your feet will never have felt so fresh, even after a long day of pushing the pedals. A compression cuff keeps them perfectly in place - no saggy sports socks here, just sock perfection.
Castelli Special Collection As we look forward to cooler temperatures and less predictable weather, it's time to delve into the Castelli special collection of winter cycling kit. With a focus on performance and style, these pieces give you warmth and comfort alongside exclusive designs that stand out amongst the rest. Winning Winter Warmth The Women's Graffiti Thermal Long Sleeve Cycling Jersey benefits from the use of Castelli's super-cosy Warmer fabric. The soft fleecy interior is incredibly comfortable and retains body heat for all-ride warmth. It also has great moisture control, preventing clamminess as you dig deep and put in some harder efforts. And if you do find yourself overheating, a smooth-sliding full-length YKK® Vislon® zipper makes ventilation control easy. As you'd expect of a Castelli, all the details are perfectly in place too. To the back of the jersey, the 3 dropped pockets offer ample space for all your cool-weather cycling essentials, from multi-tool to spare tube to an emergency rain jacket or gilet. Reflective trim keeps you visible as daylight fades and gripper elastic at the waist keeps the fit smooth. For cycling in cooler weather, this is a jersey you can trust, and in the coldest of conditions, it makes a brilliant mid-layer insulator too.
Castelli's best all-around long-distance race suit but in a sleeveless version. This suit trades the on-bike aerodynamic advantages of sleeves for the comfort and cooling of a sleeveless top. Everything else is full race performance. The short portion is built around comfort, with compressive fabrics for muscle support, the GIRO4 leg gripper that holds the leg securely in place without the dreaded sausage effect, and the KISS Tri seat pad that provides good padding and comfort on the bike yet is hardly noticeable on the run. The upper portion features the Castelli Sanremo overlapping front opening to optimize fit during the swim and run when you're fully stretched out, while avoiding folds when hunched over in the bike position. There are two generous rear pockets, and the armholes have been constructed to reduce chafing during the run. If you're not fighting for the win or a Kona slot, maybe the comfort-aerodynamics trade-off is worth it.
