Shorts

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.

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.

Whether you're going for style, protection, or a little of both, our Trail Pants are sure to be your go-to riding pant. We made them from a woven version of our lightweight and ultra-breathable VaporRize fabrics. As a result, the pants are more than tough enough to take repeated spills while you're finding your line (or losing it), without sacrificing anything to comfort. And to further this concept, they also include laser-perforated venting that's just as effective at dumping excess heat as mesh, only it doesn't create a weakness in the overall strength of the pants. In essence, this means that you won't find yourself blowing them out for a long time to come. In terms of fit, you'll find that these pants are plenty baggy enough to layer pads, but form-fitting enough to not get in the way. - Buckle waist adjustments ensure that the fit of the pant is easily customizable and dialed-in, even when your pockets are loaded. - Deflect UV 50+ protects your skin from harmful ultraviolet rays. - Designed to retain a loose and open rider-first fit while using pads and armor. - Fabric Content: MAIN FABRIC: 90% Nylon, 10% Elastane; OTHER: 82% Nylon, 18% Spandex - Laser-perforated venting adds sophisticated points of ventilation that don't detract from the durability or performance of the shorts. - Tapered leg helps to prevent anything getting caught in the chain. - Three zippered pockets provide ample, secure room to store everything that you need while you're out riding. - VaporRize woven fabrics are treated to be water-repellant, while remaining durable, stretchy, and lightweight for peace of mind on the mountain.
