Shorts/Bottoms

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

Introducing the next generation of MILLE bib shorts—building on the iconic GT Total Comfort formula with a double-layer insert and more responsive, compressive textile. Why we made it GTS marks the introduction of the second generation of MILLE—an all-new bib short that builds on the iconic GT shorts’ Total Comfort formula with its plush double-layer insert, fatigue-reducing textile, and revamped fit. We’ve engineered it for committed riders looking for added comfort during training to everyday riders seeking maximum long-distance support.

Call For Availability S9 marks the future of race-tuned comfort, built on an entirely new platform that’s been re-engineered from the ground up. With years of testing and feedback from riders at the highest level of the sport, we continue to see the most advanced insert technology being only as good as the framework that supports it. Consider the hard cornering, in-to-out-of-saddle pedaling, and hours of body repositioning that greatly impact your shorts and the way its insert functions, and ultimately the comfort both are able to provide. To address these points, we employed A-Lock Engineering, our new bracing system comprising proprietary textiles and technologies working together to stabilize the shorts and secure the insert in place. The S9 generation incorporates just two panels, with a primary “butterfly” panel fully wrapping the legs and converging in the rear to form our new ergoBox structure. This design effectively frames the insert in place and provides you with an ultra-comfortable wrap on your legs using our Type.441 textile, developed specifically for compressive hold and silky comfort. From here we added our unique rollBar, which mimics a race car’s anti-sway bar by using the bib straps to stabilize the insert as your weight transfers from left to right while cornering. Each strap is sewn into the seam directly above the insert, ensuring it’s under pre-loaded tension at all times. The bib straps have also been redesigned using calibrated stretch throughout, with the rear section using a single section of elastic material—folded over on itself—forming an A-frame in the back. It delivers limited vertical stretch in order to add further stability. In the front, the straps are made of a more flexible material, with an antibacterial carbon weave, to wick moisture and lay flat. We also focused on a single insert platform—evolved from our proven Equipe Evo—giving us the freedom to reassess what is most crucial to a streamlined, race-spec insert. We reduced the overall footprint to shed additional weight, employed superAir microShock foam with 3D waffle, incorporated our kraterCooler system to increase airflow up front, and took additional measures to anchor the insert at the rear with our patented horizontal stabilizer. The result? Signature ASSOS comfort, stabilized. Key Features: A-Lock Engineering: S9 racingFit system comprising new textiles and technologies working in harmony to stabilize the shorts and secure the insert in place. Butterfly Pattern: The primary textile panel fully wrapping the lower back and legs, coming together in the rear. Fewer seams leads to a more uniform hold, less weight, and greater comfort. Type.441: A patented 40-guage warp knit, developed specifically for compressive hold and silky comfort. 200g/m2, UPF 50+, moisture wicking (idroFil fastDry), iceColor, odorControl, and extremely durable. rollBar: A patented bracing design that mimics a race car’s anti-sway bar by using the bib straps to stabilize the insert and lock it in place as your weight transfers from left to right while cornering. ergoBox: A square pattern construction that effectively frames the insert in the back, boxing it in for added stability. Carbon Xbib: A single section of elastic material—folded over on itself—forming a supportive A-frame that delivers limited vertical stretch in the rear. Above the “X” junction, a more flexible material is employed, incorporating an antibacterial carbon weave, to wick moisture and lay flat in the front. zeroWaist: A raw-cut, tape-reinforced edge for the smoothest transition possible between the body and fabric panel. More comfort with less pressure. Ultralight Leg Grippers: A light silicon treatment woven into the leg bands, which reduces fabric bulk and secures the shorts in place without any excessive pressure. 30% Seam Reduction: Flatter seams throughout, with fewer overall, translates to more comfort and lower overall weight (180g). mod.Dep S9 Basalt: Antibacterial microfiber booster top sheet in 3D basalt colorway. Pays homage to the lava stone that gives us strength, stability, and courage. superAir microShock foam: A lightweight open cell foam with a shock absorbing composition that returns to its original position, filling the gap every time pedaling position is changed in the saddle through the shift of weight. 3D waffle: A patented, three-layer perforated foam that increases breathability and eliminates excess weight. Surface Reduction Design: Insert footprint reduced from previous Equipe Evo pattern to shed extra grams. goldenGate: A patented technology that interrupts the stitching along both of the insert’s side panels, allowing a more three-dimensional freedom of movement in this sensitive, rotational area. Horizontal Stabilizer: a patented central stitch that secures the rear of the insert to the outer textile, eliminating shifting while pedaling out of the saddle. krate

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
