Shorts/Bottoms

A bib-free training and endurance cycling short that's at home on the road or aboard the indoor trainer. Bibs aren't for everyone, but their absence compounds the difficulty of dialing the perfect ride-tuned fit. The bib-free Zero-Pressure waist embodies our C2 AEPD click-fit ethos with a secure hold on the sides and back, and a panel insert on the front stretches to accommodate aggressive positioning on the bike and deep breathing during hard efforts. The updated insert inherited increased ventilation from our premium models, and 3mm of additional thickness increase long-ride comfort. Type.429 is flexible enough for a streamlined fit; breathable enough for the heights of summer; compressive enough to respond to and support your body; and substantial enough to resist the abuse of countless kilometers. A true daily workhorse. C2 AEPD regularFit is based on our performance race models but tuned for comfort with a more forgiving Zero-Pressure waist. Streamlined performance for all-day cycling with our standard leg length.

Bibs aren’t for everyone, but omitting bib straps risks losing the stability and confidence of maintaining coverage in back and keeping the insert locked into position. We see opportunity where other manufacturers see challenge, and the H.laalalaiShorts’ combination of patterning and materials makes it seem like the answer was easy all along. Beginning at the wide, unrestrictive waistband, the shorts rise across the lower back to eliminate gaps between shorts and jersey and provide an anchor to hold the compressive paneling and insert in place. No need for constant readjusting in either direction. The waistband’s effective minimalism extends through the shorts’ bodies, whose clean aesthetics are the result of function-first design privileging gentle compression, seam reduction, and years-long durability.

S7 generation: the latest generation of ASSOS cycling shorts, employing technology and fabrics engineered over a 5-year period. Type.439 Diadema: A unique textile, engineered with expertise that uses a 4-way stretch to maximise the elasticity of the fabric. aeroPatterningFenomeno1 design: Drawing on learnings from our project to create the fastest skinsuit at the 2012 Olympics, this original design involves crafting the garment with a single seam that sits on the rear of your legs causing the main fabric of the shorts to wrap around your thighs, providing a unique level of comfort and compression. Half-leg flat grippers: Ultra lightweight grippers with optimally calibrated stretch that secure the shorts around half of the leg circumference, for less compression and more comfort. iceColor: A fabric treatment that reflects sunlight and thus reduces heat absorption to keep muscles cooler. Lady_S7 insert: A women’s chamois pad offering superior comfort and performance with 8mm of memory foam and a patented elastic insert interface to reduce friction. ASSOS goldenGate: A patented technology which augments the performance of the insert by allowing the most fluent movement with the body. ASSOS Waffle: A unique, three-layer foam used in our inserts with perforations that make it light and highly breathable. Y7 frame carrier bibTech: A bib redesign that involving using a wider cut of elastic for less pressure on your shoulders, resulting in less friction and more comfort. Schnalle: A performance-orientated magnetic clasp running down the centre of your chest that is easy to fit and unclasp. Composition: 73%PA 18%EA 9%PL

The absence of bib straps compounds the difficulty of dialing the perfect ride-tuned fit. To address that, we reimagined the waistband with a stabilizing elastic layer that anchors the fit and an additional top band of mesh that extends coverage, independent of the elastic band, for comfort, moisture management, and to eliminate gaps between shorts and jersey while in the saddle. The updated insert features increased ventilation, a reduced footprint, and a new Odor Control Top Sheet Tex in Sugar Blue.

A new solution for women’s cycling: comfortable, performance-tuned bib shorts that allow natural breaks without removing jerseys, vests, or shells. BEHIND THE PRODUCT We took feedback on our T.LaalalaiShorts_s7 to heart, revisiting our women-specific design with an all-new solution that better facilitates natural breaks with two magnetic closures at the rear rather than a single closure at the front center. The textile was also improved, shedding grams and gaining permanent odor-control and active cooling. It’s also a deeper, richer black, which pops on the bike in full sunlight.

WHAT IT IS A new bib short platform for committed daily riding, whether that’s dedicated training regimens, the weekly crit series, or weekend centuries. WHY WE MADE IT We wanted an all-inclusive solution for daily riding. That’s simple in concept; it’s more complicated in the execution. To meet our expectations, we built the premier UMA GT on a platform of trickledown tech, including an updated AEPD fit profile and bib suspension infrastructure. We also updated the insert, reducing the footprint, and adding an aesthetic touch with the Odor Control Top Sheet Tex in Sugar Blue.

The next generation in committed riders' bib shorts of choice, defined by its frictionless waist, refined air-cooling insert, and muscle-wrapping textile. We took this generational redesign as an opportunity to make the MILLE GT better at the things we loved about its predecessor, including our premium X-frame suspension carriage, a refined comfort waist fit, and a reduction in seams and weight (28% and 5g, respectively). The insert also got some attention, inheriting the increased ventilation of our GTS/GTO models and receiving 3mm of additional cushioning. We also updated the Odor Control Top Sheet Tex to the Sugar Blue colorway. - 80%PA 20%EA

Our flagship WorldTour bib shorts for racing, dedicated training, and cyclists who appreciate how meticulous engineering and refined equipment can help athletes achieve higher performance. The “TARGA” classification indicates a foundational redesign of our EQUIPE RS S9 platform. The reengineering process increased performance and comfort, shed unnecessary bulk and grams, and decreased drying time—which ensures perspiration doesn’t add mid-ride weight by lingering in textiles. We also incorporated a panel of Ossidia material across the lower abdomen, adding stretch to better accommodate aggressive bike positions, expand with deep breathing during hard efforts, and relieve pressure for taller cyclists seeking an aerodynamic, second-skin fit.

WHAT IT IS The next generation of our flagship WorldTour bib shorts, reengineered with lower weight, increased cooling breathability, and more comfortable, body-wrapping compression from waist to raw-cut leg openings. Available in standard or long (+3cm) leg length. BEHIND THE PRODUCT The critical updates to the new EQUIPE RS shorts are a new textile and a new insert. The new textile, Type.911, allowed us to completely reengineer the cut, reducing the seam count and wrinkles while micro-adjusting fit across the legs and waist. It also let us eliminate the rollBar bib strap design, because Type.911 is more elastic and more compressive than the Type.411 used on the previous generation. Rather than merely suspended from bib straps, the S11 shorts envelope the rider’s body in omnidirectional, body-mapped stability. The new RS S11 insert’s top sheet is both softer against the body and more durable for washing, and it has an improved odor control treatment while maintaining its predecessor’s cooling airflow, micro-shock damping, and lowvolume, lightweight profile

The main story of this short is the use of our renowned top-of-the-line progetto x2 air donna seamless seat pad in a mostly traditional short, but in fact every little detail has been obsessed over to ensure your comfort on your next long endurance ride. A great pad is useless without great fit. The seams are placed around the hip area to create a perfect shape on the bike. The endurance evolution fabric has a soft hand while providing good compression and excellent moisture management. And it's all held in place with the amazingly comfortable giro3 leg gripper. On your long endurance rides you'll especially appreciate Castelli's drop-tail bib construction. The wider bib straps are free-floating so you can cross them in front or back. They pull tight enough to keep your shorts in place, but when the need arises they stretch long enough that you can take a bathroom break without having to remove your jersey and bibs. This short offers exceptional value and is ready to deliver lasting comfort on your longest rides. - Endurance evolution fabric provides optimum muscle support and feels drier in nearly all conditions - Anatomic cut for perfect on-bike fit - Bib straps can cross in front or back and are extra elastic, allowing short to be pulled down for pee stops without removing bibs - Women's-specific progetto x2 air donna seamless seat pad for even greater comfort and improved airflow - Giro3 leg grippers lie flat

Innovative evolution The free aero RC bibshort is our top race short, which also means that it's insanely comfortable even if you never pin on a number. It's fair to say that we've been working on this short for the past 15 years. That's how long it's been since the original free aero race bibshort was first introduced, initially as our top-of-the-line race short. The various versions of the free have dressed all our pro women's teams over this time, and it also became the best-selling women's short in the history of Castelli because simply put, this is the short that does everything well. The concept is quite simple: start with the best pad we know how to make, surround it with a supportive short with good muscle compression, and then remove everything else that's not absolutely necessary. You feel free thanks to the reduced number of panels and the reduced number of seams. In fact, the short portion has just 5 panels compared to 10 in the previous generation. You feel free because of further refinements to the Progetto x2 air seamless seat pad. The two densities of foam plus the gel pads provide progressive damping, while the separate skincare layer is soft and stretchy to move with your skin. You feel free thanks to the most minimal bibs you've ever seen in a short, including open-weave straps for maximum airflow. But we reinforced the yoke so the straps stay in place and made the mesh back narrow for coverage that is minimal yet just enough to hold the shorts in place. And the bib elegantly frames a convenient pocket at the center back. You feel free because this is the first high-end short that doesn't need any sort of gripper or elastic at the end of the leg to keep the leg in place. Getting this right meant 28 prototypes and our most extensive test program ever, and it results in the most comfortable leg ending we've ever made. The Forza 2 fabric has 32% lycra with a high modulus for exceptional muscle support and just the right amount of compression. There's reflective piping on the back. And all logos are either stitched or embossed for durability. - High-compression 215 g Forza 2 fabric with 32% lycra content provides exceptional muscle support and compression - Women's-specific Progetto x2 air donna seamless seat pad is soft against the skin but well padded for long-distance comfort - Minimalist bib straps allow maximum airflow, while a reinforced yoke keeps the straps flat over the shoulders - Rear mesh pocket - 5-panel construction for reduced seams and less chafing - Stitched scorpion logo patch and embossed Castelli wordmark for durability - Reflective piping on back of legs - Raw-cut edge at waist for extra stretch and comfort - Raw-cut leg ending engineered to stay put without silicone grippers

The new women's Premio Bibshort has been engineered to provide the ultimate in long-distance comfort and to be your favorite bibshort ever. That's a big claim, but there's a lot of development in this short to back it up. So let's take a tour of the short. The first thing you might notice is what's missing: the seams and multiple panels. We engineered a new fabric that changes depending on the needs over various parts of the body. The lower leg has a raw-cut leg ending and rubberized yarns to guarantee a flat grip to keep the leg in place. The fabric becomes lighter in the thigh, while the four-way stretch provides just the right amount of muscle support. In the pelvis area, the compression and support increase to hold the seat pad firmly in place, and the fabric gets thicker to avoid any embarrassing transparency issues. With this magical fabric we don't need to stitch separate panels together, which ensures more comfort and a better fit, as well as a sleek, sophisticated look. The premium fabrics extend into the bib straps. The perforated back keeps you cool and the edge is bonded so you don't feel the thickness of a stitched edge. The elastic straps have just enough modulus (return) to hold your shorts securely in place without cutting in to your shoulders. The seat pad is our top-of-the-line women's-specific Progetto X2 Air Seamless pad with four layers, two separate densities of foam and breathable perforated gel inserts in critical areas. We've extended the attention to detail to the laser-etched logoing and subtle finishing. It looks as premium as it feels. You can tell that every component, every stitch, every detail has been obsessed over. You'll not find a better bibshort. - The premium all-conditions short - Gradient stretch woven fabric for the right support in the right place - Woven fabric weighs 30% less than comparable knit fabric - Perforated bib straps lie flat and don't bind at shoulders - Integrated gripper elastic at leg ending holds short in place without need for extra silicone grippers - Laser-etched logos and stretch silicone scorpion heat transfers - Women's-specific Progetto X2 Air Seamless Donna seat pad

The Premio Black W Bibshort has been engineered to provide the ultimate in long-distance comfort and to be your favorite bibshort ever. That's a big claim, but there's a lot of research and development in this short to back it up. The seat pad is central to the Premio’s exceptional comfort and our top-of-the-line women's specific Progetto X2 Air Seamless Donna pad is actually two separate components: a soft, stretchy Skin Care Layer next to your skin, which has the sole purpose of preventing any rubbing on your skin, and, under that, the Cushioning Layer, which features two separate densities of foam along with breathable perforated gel inserts under the ischia bones and perineum. Comfort continues through the construction of the short with reduced seams and only 3 panels. We engineered a new fabric that changes depending on the needs over various parts of the body. The lower leg has a raw-cut leg ending and rubberized yarns to guarantee a flat grip to keep the leg in place.

The premium fabrics extend the bib straps. The perforated back keeps you cool and the edge is bonded so you don’t feel the thickness of a stitched edge.
