MILLE GTO Bib Shorts S11

Assos MILLE GTO Bib Shorts S11

The Assos MILLE GTO Bib Shorts S11 are designed for long-distance comfort and clearly elevate the endurance class with the latest S11 generation. From the new, lighter strap construction for improved breathability to the low-friction leg finish with integrated silicone grip, every detail is tuned for long days in the saddle. The main OSSIDIA fabric delivers silky-soft compression, while a LOSANGA front panel combined with the kukuPenthouse construction noticeably improves airflow through the chamois. Available in two leg lengths – standard and long (+3 cm) – plus seven sizes from XS to 3XL, ideal for the Swiss market and a wide variety of rider types.

• GTO S11 Insert with Shock-Absorb Damping System Twin: dual-layer, 21 mm thick platform with additional support beneath the sit bones.
• goldenGate 2.0, kraterCooler and whirlKrater for reduced friction and noticeably more cooling directly in the chamois.
• rollBar strap stabilization keeps the chamois precisely in position during sprints, climbs and cornering.
• INject leggripper: silicone grip integrated into the fabric at the raw-cut leg openings – less friction, secure hold.
• cranKio Tec shaping at the hips prevents bunching during pedaling and minimizes friction.
• OSSIDIA main fabric for balanced muscle support and LOSANGA insert for pressure relief and improved ventilation.
• zeroPressure Waist for comfortable, pressure-free fit at the waist.
• Two leg lengths (standard/long +3 cm) and seven sizes (XS–3XL) for a precise fit.

Technical Details and Features

At the core is the new GTO S11 Insert: a dual-layer, 21 mm thick damping platform that absorbs impacts and works with additional support beneath the sit bones. The goldenGate 2.0 suspension allows the chamois to move laterally with your body, reducing pressure peaks; kraterCooler openings and distributed whirlKrater perforations increase cooling airflow. The OSSIDIA main fabric is a finely tuned warp-knit with ultra-fine elastane yarns for gentle, fatigue-reducing compression and smooth, low-friction contact with the skin. For additional ventilation and pressure relief, LOSANGA at the front combines with the proven kukuPenthouse, while the INject leggripper delivers permanently secure hold without the bulk of a traditional silicone band. The construction is rounded out by rollBar straps for vertical stabilization and the zeroPressure Waist for relaxed fit at the waist; the legs consist of 80% polyamide and 20% elastane.

Applications and Benefits

These bibs are the first choice for extended road bike tours, Alpine passes and brevets, when consistent damping, cool microclimates and stable fit are crucial. The ventilation-friendly chamois construction plays to its strengths in summer temperatures and intense indoor sessions, because the airflow reduces friction and moisture. Those who prefer more coverage choose the long version (+3 cm) for a modern silhouette and a bit of extra protection from sun and spray. The rollBar stabilization keeps everything where it belongs, while cranKio Tec prevents bunching – ideal for long, steady cadences on Swiss roads. Additionally, the S11 generation stands brand-wide for lighter straps and improved ventilation around the chamois, which independent tests of the current S11 line confirm in terms of heat management.

Sizes, Fit and Variants

The MILLE GTO Bib Shorts S11 follows the Assos-typical regularFit with a close-to-body but not overly compressive cut – ideal for long distances without sacrificing freedom of movement. Available in seven sizes from XS to 3XL, reliably covering even more athletic builds. Two leg lengths – standard and long (+3 cm) – make it easier to fine-tune for style, proportion and application. Material-wise, the legs consist of 80% polyamide and 20% elastane; the front insert integrates 78% polyamide and 22% elastane, while the chamois cover uses 85% polyester and 15% elastane.
