Shorts/Bottoms

GTO marks the pinnacle of the Total Comfort MILLE GT line - spiritual successor to the iconic CENTO and Campionissimo Bib Shorts. It features the plushest, most responsive and breathable ASSOS insert to date, wrapped in our new frictionless, wrinkle-free paneling. The GTO has two leg lengths: STANDARD and LONG (+3cm vs standard). BEHIND THE PRODUCT With large-muscle support, friction, and excessive pressure remaining critical issues on long-duration rides, GTO destroys conventional bib short construction formulas. We reversed stitch lines and radically reshaped the insert to eliminate friction and genital pressure, while providing matchless muscle support with tapered, wrinkle-free leg panels that mirror your personal physique.

The 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 keep the seat pad and everything else 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 Progetto X2 Air Seamless pad. It's 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. We've carried the less-is-more theme into the design, with minimalist laser-etched logos 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 back bib panel with lie flat bib straps that don't bind at shoulders - Integrated gripper elastic at leg ending holds short in place without need for extra silicone grippers - Laser-etched logos with RossoCorsa at center back and black scorpion shadow logos at lower legs - Progetto X2 Air Seamless seat pad

The definitive bib shorts for competitive, committed cyclists from the company that originally defined the racing shorts genre—and continues to lead in driving it forward. It’s only fitting that the latest generation of ASSOS inserts—the most advanced available from any manufacturer—is partnered with bib shorts completely re-engineered, with no design choice taken for granted or left unquestioned. The resulting bib shorts are atypically advanced—which makes them typically ASSOS. The shorts combine textiles and technology in an interwoven network of wrapping compression, silky comfort, and tensile pre-load to keep everything from the leg panels to the insert securely in place. It’s taken six years of in-house development and testing by WorldTour riders, but the EQUIPE RS S9 Bib Shorts are the definitive statement in cycling shorts from the cycling shorts company.

ASSOS has given riders all over the world the highest level of performance and quality for over four decades. They invested five years developing the S7 generation of shorts and created the acclaimed T.équipe_S7. Equally at home in the pro peloton and on a speedy commute, these riding shorts have everything you need and nothing you don’t. Coming in the ASSOS racingFit and employing the aeroPatterningFenomeno1 design, all of the ASSOS garment insights are combined here to accelerate your ride. The free speed can be felt at once. Equally significant to the T.équipe_S7 bibs is the all-round feel and durability supplied by the next level materials employed. Little wonder that the experts in pro test teams rate the T.équipe_S7 so highly. River City Bicycles logo printed on both sides. S7 generation: the latest generation of ASSOS cycling shorts, employing technology and fabrics engineered over a 5-year period. racingFit: A fit that is is tighter and slightly more compressive than our alternative regularFit and comfortFit options. May feel restrictive out of of the riding position but feels like a second skin while riding and results in a higher performance, improved comfort and less drag. Type.439 Diadema: A textile design created with our fabric suppliers to meet our demands of performance, comfort and durability. Unique within the industry, the weave has two different rates of 4-way stretch, requiring great expertise to maximise the elasticity of the fabric on the cutting table. 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. 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. équipe_S7 insert: A chamois pad offering a deft balance of performance and comfort with 8mm of memory foam. ASSOS waffle: A unique three layer foam used in our inserts with perforations that make it light and highly breathable. ASSOS goldenGate: A patented technology which augments the performance of the insert by allowing the most fluent movement with the body. superFlat grippers: Ultra minimal grippers with optimal stretch return to secure the shorts in place without any excessive pressure. iceColor: A fabric treatment that reflects sunlight and thus reduces heat absorption to keep muscles cooler. odorControl: An anti-bacterial treatment that reduces unpleasant odors and improves durability.

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. Since then it has won three Tours de France, three Gri d'Italia, one Vuelta, and San Remo, but it also became the best-selling product 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 215g Forza 2 fabric with 32% lycra content provides exceptional muscle support and compression - Progetto X2 air 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 - Sublimation-printed graphic and logos that will never peel, crack, or fade - Reflective piping on back of legs - Soft waistband with raw-cut edge panels for extra stretch and comfort - Raw-cut leg ending engineered to stay put without silicone grippers

Professional-grade racing bib shorts. - Protection from the sun on long training rides and race days (UPF 50+) - New pattern fits more riders even better - Aerodynamic patterned fabric is strategically placed on the sides and back panels - 27cm/10.5" inseam (size medium) - Seamless construction at the back of the thigh reduces pedaling friction - Flat bib straps with supple elastic mesh fit comfortably on or off the bike - Highly durable fabric with exceptional shape retention delivers a long-lasting superior fit - Integrated flat leg grippers hold the leg more securely

A breathable, lightly insulated half knicker engineered for spring/fall conditions when tights are too warm and shorts are too cool. We engineered these knickers for fall and spring rides where knee coverage and a touch of insulation are just the ticket, as they feature a blend of ultrasoft and insulating fabrics, along with our proven female-specific insert and signature regularFit. RX EVO makes up the majority of the paneling. This brushed warp-knit fabric provides exceptional comfort, wicks moisture, adds high levels of insulation, and remains extremely flexible. The waist benefits from ultrasoft warp-knit Aerofit, which is knitted with an open structure for maximum ventilation and featuring high elasticity plus built-in odorControl. The knickers' fabric technology ensures that the fronts of your legs stay shielded from biting winds and cold air, while the backs benefit from added breathability. Its fold-over front panel design at the waist creates a smooth, pressure-free transition between the body and fabric.

The evolution of our iconic long-distance bib shorts, offering the smoothest transition possible between the body and fabric for improved comfort over the long haul. CENTO is synonymous with long-distance comfort, and ASSOS engineered this latest iteration to advance that sentiment one step further. They began with the same proprietary fabric, which features two different rates of four-way stretch and delivers a compressive hold for a smooth supportive wrap along the thighs. As with the original CENTO, ASSOS made the fit a touch more generous around the lower abdominals for endurance rides, and added a tape-reinforced waist to ensure a smooth and comfortable hold on a variety of body types. For dependable comfort, support, and performance on every ride, ASSOS has given you 10mm of plush memory foam encased in a black insert.

Bringing up the rear of the exclusive River City Bicycles Acrostic kit, the Free Aero Race 4 Bibshort is Castelli's top race short, which also means that it's insanely comfortable even if you never pin on a number. The original Free Aero Race Bibshort was first introduced over a decade ago and has logged literally millions of kilometers under the backsides of their sponsored pro riders and has been the best-selling short both in the Castelli retail collection and in their Servizio Corse custom program. Over this time the short has undergone numerous updates and improvements in the never-ending quest to create the best short. While the basic concept of a minimalist workhorse pro-level comfortable race short remains, every single fabric, component, stitch and construction method has been updated and improved over time. The fourth major generation of the short features the updated Progetto X2 Air Seamless seat pad. This pad separates a soft, stretchy skin care layer that moves with your body from a generously padded cushioning layer that replicates the form of your saddle. Eight-hour rides are no problem. Of course the fabrics are premium, made to Castelli's specifications by Italy's best fabric suppliers. The Forza fabric on the inner leg features 38% Lycra® content for perfect fit, while the Vortex fabric on the side panels is dimpled for aerodynamics. And it's held in place by the latest iteration of Castelli's seamless flat Giro leg gripper.

The Women's Chrono Elite Halter Bib Short is a luxurious, high-performance bib with timeless style that also makes less impact on the planet.

Ideal for those cool fall and spring rides where added knee coverage and a touch of insulation make all the difference, the MILLE GT Spring/Fall Knickers are constructed with a blend of ultrasoft and insulating fabrics, paired with the evolved MILLE GT insert. To make a knicker that would meet the demands of these variable conditions, two custom insulated textiles are added to the design. RX Heavy makes up the majority of the paneling-a beefed-up version of our workhorse RX-featuring an ECO water-repellent treatment for further protection from light precipitation. This fabric ensures the fronts of your legs stay shielded from biting winds and cold air, while the backs of the legs are made up of RX Light for added breathability in this high-flex zone. The fit of the MILLE GT Knickers falls into the regularFit category, which means they're lightly compressive where they need to be, but not as tight as our racingFit apparel. The fabric panels flex with each pedal stroke, as they're both pre-shaped and sewn to fully wrap and support the upper leg muscles, knees, and calves while in motion. The insert is the MILLE EVO, featuring 8mm of plush memory foam for dependable comfort on every ride.

Our Supergiara Bibshort has revolutionized the understanding of comfort over long distances off-road. This version is a tribute to the denim aesthetic that has frequently left its mark on the history of fashion, as well as of cycling itself. - Denim effect created with a printing technique that changes the look with each wash, as with real jeans - Mesh cargo pocket on left side and 2 pockets on back - Reflective bands on lower part of legs - Anatomic design for greater comfort and airflow

Gravel, touring, and bikepacking require more robust equipment. Frame, wheels, tires, clothing—none of a rider’s gear is exempt, so the KIESPANZER (or “Gravel Tank”) provides the requisite durability for the inevitable abuse of cycling beyond the tarmac. It’s also equipped with storage solutions for day-trip supplies or to supplement pack space and keep ride essentials readily accessible in pockets of high-stretch, extremely breathable 3-Mesh panels. Reflective stripes help ensure visibility on early departures, late returns, or those long dusks while pushing through the final miles to the next hotel or campsite.

Our Flexair Race Pants are a game changer on the mountain. With a superlight, tapered fit, these MTB pants climb as well as they descend. The exceptional TruDri moisture-wicking properties, TruMotion all-way stretch, DWR-coating, and targeted ventilation will make these the most comfortable mountain bike pants in your arsenal. Our proven race-ratchet closure system allows for quick and easy adjustments to provide the perfect fit, while zip pockets keep your essential items secure.

We like a comfortable bib short that's compressive, but not restricting. When we're riding up a canyon with burning thighs and the will to power through, the last thing we want is discomfort from our bibs or jersey. Assos designs gear for these moments so athletes can carry on pedaling through the tough stuff without a hitch. The brand's T GTS - Mille GT C2 Bib Short ensures that riders will have a good time on their bike no matter if it's a training session or a Sunday morning ride with the group. Custom fabric blends, a refined insert, and versatile fit ensure lasting comfort on all rides. For a performance-based balance, the Mille elastic interface insert is employed with 13mm of memory foam to ensure cushioning, and a 3D waffle perforated foam increases breathability in turn. Lightly compressive 4-way stretch ensures flexibility in the bib's fabric, and superFlat grippers keep everything in place without excessive pressure. Reflective accents offer additional safety measures in low-light situations.

Trusted by committed riders the world over, the time-tested MILLE GT Bib Short is defined by its frictionless waist, air-cooling insert, and muscle-wrapping textile. Assos leaned more toward comfort versus race in the bib shorts’ design, which mates a custom fabric blend with their regularFit to result in a performance piece for training, racing, or simply riding in total comfort. Assos built the bib shorts with a lightly compressive textile with high elasticity to ensure a comfortable and consistent hold on your legs while pedaling. At the front waist Assos used a raw cut with taped reinforcement to ensure the cleanest and most comfortable transition possible between the abdominals and front fabric panel. To construct the back panel, Assos recruited their acclaimed design to produce a flat, stable structure that disappears between the shoulder blades for a smooth supportive hold.

There's quite a few boxes that your "favorite pair of bib shorts" must check. The chamois has to be perfect—soft to touch, foam in all the right places, and perfect shape. And the materials must be compressive, yet still comfortable while being sized correctly. It's been a lengthy process, but we're happy to say that the SL Race Bib Shorts check all the right boxes. The pre-molded, triple-density foam Body Geometry Contour 3D Chamois is contoured to perfectly match the curvature of your body, all while being soft and supportive in all the right places.

The three-inch-tall silicone cuff also ensures that your bibs stay in place in a variety of conditions. - Compressive four-way stretch fabric provides ample leg support, comfort, and a soft hand. - The open suspender construction is designed to keep the bibs in place without constricting the upper body.
