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.

The next generation in committed riders’ bib shorts of choice, defined by its frictionless waist, refined air-cooling insert, and muscle-wrapping textile. Assos took this generational redesign as an opportunity to make the MILLE GT better at the things we loved about its predecessor, including their 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. Assos also updated the Odor Control Top Sheet Tex to the Sugar Blue colorway.

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.

The next generation of Assos' flagship WorldTour bib shorts, re-engineered with lower weight, increased cooling breathability, and more comfortable, body-wrapping compression from waist to raw-cut leg openings. Available here in a standard leg length. The critical updates to the new EQUIPE RS shorts are a new textile and a new insert. The new textile, Type.911, allowed them to completely reengineer the cut, reducing the seam count and wrinkles while micro-adjusting fit across the legs and waist. It also let them eliminate the rollBar bib strap design, because Type.911 is more elastic and more compressive than the Type.441 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 low-volume, lightweight profile.

This short gives you every reason to step up to Castelli. They have innovation in our DNA. They've brought you most of the innovations in a cycling short over the years: the first Lycra® shorts on the market and the first flat leg grippers. All these advances have become industry standards, and they keep pushing and innovating in high-end shorts. The Entrata short is where all that knowledge and experience trickles down into a short that just plain works. The fabric is just the right weight with just the right stretch and with a matte finish that looks just right. The KISS Air2 seat pad is just right, as is the GIRO3 leg gripper. And the short fits just right because they obsess over the fit of every short we make. Castelli wanted this short to be just right for many years to come, so they stitch on the logos and stitch in the reflective panels on the back. The Entrata short is just right for you.

And although it's certainly capable of weekend racing, it's also a great comfort performance short even if you never pin on a number. The main Vortex textured fabric and the Giro4 leg gripper come straight from Castelli's top Free Aero Race 4 Bibshort, while the KISS Air2 seat pad has most of the comfort of their top seat pad but represents maximum value. The intangible part that you'll appreciate most is their knack for building in perfect fit, thanks to the Castelli pattern engineering team. This is the short that brings the best of Castelli's know-how in building comfort performance shorts into an accessible product in your cycling wardrobe. Weight: 173 g Men's Fitted profile

When Castelli set out to make this bibshort, the idea was to make the short that they would grab the moment it's dry after being washed, no matter what kind of ride is on the calendar for that day. So that's what they did. First, Castelli developed a soft, stretchy fabric that feels amazing on the skin the second you put the short on. This fabric forms and moves with the body without being tight or constrictive. They paid extra attention to the fit to make sure everything stays where you want it, but they added silicone gripper at the leg ending just to make sure your tan line stays crisp. The mesh bib straps are stretchy while allowing extra ventilation. Of course, they've used their Progetto X2 Air seat pad for all-day comfort. Finally, Castelli added some extra details like a rear pocket for storage and reflective tabs for added safety. All of this makes the Espresso our, and your, new favorite bibshort.
