Belgian legend of the 1980's Freddy Maertens, a two-time world champion, asked ASSOS to create a heavier bibshort that could be used for tough autumn riding in Belgium. A landscape renowned for it's cold and windswept roads. ASSOS did. These Assos T. tiburu_s7 Bib Shorts are the modern incarnation of that first heavier weight bib short.

The ConstructionASSOS wouldn't be ASSOS if they took the existing s7 platform and just changed it to a heavier fabric. No! ASSOS went the extra mile and incorporated two additional ASSOS inventions: 1. BlasenSchutz (bladderProtection) ASSOS first incorporated this feature with the s5 winter tights (2010). The front panel between the crotch area and the abdomen features ASSOS Stratagon wind-block fabric. This ensures your bladder is not exposed to chill winds, which reduces the need to urinate while riding. 2. Integrated front pad protection (IPP) The insert platform used is from the s7 model équipe, but it features a new front construction. The insert is not sewn directly to the fabric. Instead, it continues to the panel end. This provides an extended layer of protection and no seams at all in the front area. Increased protection, greater comfort. Really nice and functional. Another ASSOS invention, another step towards total comfort. Campionissimo AEPD (Advanced Ergonomic Pattern Design) Like all ASSOS products, the T. tiburu follows their maxim: tailored to fit on the bike in the cycling position. T. tiburu contours to your body like a second skin, featuring the innovative s7 game changer panel platform. Reduced weight, fewer seams, less friction, more stable fit. Given the nature of its purpose and the target riders, T. tiburu has a racing fit. ASSOS Textile labThe T. tiburu is the first ASSOS product to feature the brand new custom type 610. RX fabric, an evolution of the legendary RX series. Everything got better and now featuring AWR, ASSOS Water Repellent technology, ideal for riding in damp, drizzly or light rain conditions. The fabric is a brushed bi-stretch warp knit fabric with new improved construction, increased abrasion resistant with better thermal insulation. The lower abdomen features ASSOS Blasenschutz technology: Using 716. Stratagon Ultra, a comfortable bi-stretch two-layer fabric, this features excellent wind blocking and water repellency plus highest moisture vapor permeability (MVP) allowing excess perspiration to escape keeping wind-chill at bay.
