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.

Lightly insulated knickers for cool conditions and long-distance riding, with extended knee coverage and stormproof textiles. Updated with features to enhance stability, reduce seams, and improve support. We redesigned the pre-shaped panels to reduce seam count, and we also shed grams without sacrificing the light compression and long-distance comfort MILLE embodies. The Knickers are updated with our race-inspired X-Frame bib design, which stabilizes the insert and body panels throughout the pedal motion and while cornering. The new model is also updated with our MILLE GT C2 insert, which adds 2mm of plush comfort for long rides maintaining form or building base miles for the coming season. - 86%PA 14%EA

Breathable, lightly insulated tights engineered for cool spring and fall conditions, updated with increased fit security and a more comfortable long-distance insert. We completely reengineered our Spring Fall Half Tights with a new waist design and a new insert – in short, it’s an entirely new platform. The new waist is our hipClick construction, which stabilizes the leg panels and insert by locking into place with a supportive, unrestrictive fit. The updated UMA GT C2 insert shifts cushioning to support more upright, less aggressive riding positions – ideal for comfort over longer distances while training or touring.

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

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.

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 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

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.
