The ASSOS MILLE GTO Bib Shorts S11 represent the pinnacle of endurance cycling bib shorts, engineered for riders seeking maximum comfort, stability, and long-distance performance. Developed on the advanced S11 platform, these ASSOS endurance bib shorts refine the brand’s flagship MILLE GTO concept with improved compression, breathable textiles, and an advanced insert system designed for extended hours in the saddle.
Constructed with high-performance compressive fabrics, the shorts stabilise the muscles while maintaining excellent elasticity and airflow during warm-weather riding. The ergonomic panel construction works together with ASSOS’ stabilising suspension system to keep the insert perfectly positioned as the rider moves on the bike. The MILLE GTO S11 insert is engineered for ultimate endurance comfort, combining multi-layer cushioning with advanced ventilation to reduce pressure and heat buildup during long-distance efforts.
