Capo uses its Super Roubaix SL fabric to create a bib short with a bit more insulation than your typical bibs: Capo rates it for riding in a temperature range between 40 and 60 degree Fahrenheit when combined with leg warmers. The bib short's medium gauge compression provides support to muscles and decreases fatigue during your ride, meaning you'll pedal better for longer. Bibs, of course, are the way to go for performance cyclists: there's no waist band to create irritation points, and the shorts and chamois stay right where you want them, as the short moves with you. There is arguably no more important interface between rider and bicycle than at the saddle-and it's the shorts and integrated chamois that can make all the difference. Capo's top of the line Anatomic 4G Carbon EIT (Elastic Interface Technology) insert has justifiably been dubbed a "six-hour chamois." Whether your ride lasts 30 minutes or all day long, the variable thickness pad with ultra-high-density perineal inserts will ensure that it's a comfortable outing. And the Carbon Microfiber used in the chamois provides anti-microbial protection and quick moisture transfer to keep you dry and prevent chafing and saddle sores. The Capo GS SL Roubaix Bib Shorts use Element 4 fabric on the leg grippers for a great deal of reflectivity. The result: you'll be extra visible-and thereby safer-to vehicles when riding in low-light conditions. The GS SL Roubaix Bib Shorts themselves use a twelve-panel construction to provide a streamlined, high-quality fit. When you need just a bit of extra protection on cooler to cold days, start with the Capo GS SL Roubaix Bib Short, and add on as necessary with base layers, leg warmers, and pedaling. Ride on into autumn and beyond.
