Assos MILLE GTO Bib Shorts S11 Long
The Assos GTO S11 Bib Shorts represent the ultimate expression of long-distance cycling comfort, refined through decades of innovation to deliver uncompromising performance for riders who demand the absolute best. Synonymous with endurance excellence, this latest generation elevates breathability, stability, and cooling airflow from shoulders to leg openings, redefining what luxury comfort means on the longest rides.
Engineered with Assos's proprietary OSSIDIA textile, the GTO S11 provides silky-smooth, muscle-wrapping compression through ultrathin elastic yarns that deliver gentle, fatigue-reducing support exactly where riders need it. Body-mapped elasticity ensures consistent compression without restriction, while the ultra-elastic LOSANGA front panel reduces pressure and dramatically increases cooling airflow for superior comfort during extended efforts.
The GTO S11's upper body features redesigned lightweight bib straps that enhance ventilation and reduce bulk, working in concert with the rollBar stabilization system—borrowed from Assos's Racing Series—to keep the chamois insert perfectly positioned during dynamic pedaling. The zeroPressure waist delivers soft, restriction-free support, while cranKio Tec hip shaping eliminates excess material to prevent bunching throughout the pedal stroke.
At the leg openings, innovative low-volume, open-structured grip rings replace traditional silicone bands, maintaining secure hold while improving airflow and reducing friction against the skin. This thoughtful detail exemplifies the GTO S11's commitment to refined comfort through intelligent design.
The centerpiece of the GTO S11 experience is its advanced dual-layer 21mm endurance insert. The Shock-Absorb Damping System Twin construction provides targeted ischial support calibrated specifically for long-distance riding positions, while goldenGate 2.0 technology allows the insert to float naturally with the body's movements. The kukuPenthouse construction enhances front ventilation and pressure relief, while kraterCooler and whirlKrater perforations generate multidirectional airflow, creating a cool, dry microclimate even during the most demanding rides.
For cyclists who refuse to compromise on comfort during century rides, gran fondos, or multi-day tours, the Assos GTO S11 Bib Shorts deliver the endurance luxury that separates extraordinary rides from merely long ones.
