Assos Mille GTO S11 bib shorts 2026

The pinnacle of endurance comfort, refined with a frictionless infused leg gripper, a construction that sheds weight while increasing comfort, and an ultraplush insert that’s as cooling as it is comfortable. Available in two leg lengths: standard and long (+3cm). GTO is synonymous with luxury comfort in the saddle, and the latest generation does nothing but improve on that reputation. Comfort increased from the shoulders – where new, lighter bib strap construction increases breathability – to the leg openings – where the traditional silicone grip is replaced by low-volume, open-structured rings to maintain grip and improve airflow. The cranKio Tec darting at the hips eliminates material that might bunch during the pedal stroke, and a front panel of ultra-elastic, ultrabreathable LOSANGA textile is matched with the classic kukuPenthouse construction on the front of the insert, drastically increasing cooling airflow through the insert. the proven OSSIDIA textile wraps your large muscles in silky-smooth compression, and the GTO S11 Insert – the most comfortable endurance model in the world – is locked into place by the stabilizing rollBar bib strap construction.

Featured Fabrics
The primary textile, OSSIDIA, strikes the ideal balance between frictionless comfort and muscle-supporting compression. Its warp-knit construction incorporates ultrathin elastic yarns for gentle, fatigue-reducing compression and body-mapping elasticity that wraps your large muscle groups in silky-smooth comfort. An insert of LOSANGA on the crotch panel eliminates pressure and increases cooling airflow.

Construction/Fit
The epitome of the regularFit, engineered for total comfort on the longest rides. The GTO model is upgraded with cranKio Tec, targeted shaping on the hip that eliminates bunching during the pedal stroke.

Rollbar
A patented bracing design adapted from the Racing Series. Stabilizes the insert and locks it in place as your weight transfers while sprinting, climbing, and cornering.

INject leggripper
Silicone grip infused through the back of the raw-cut leg opening, reducing friction and protecting the grip from sun or sweat damage while maintaining secure hold.

CranKio Tec
Reduces wrinkling across the front of the hips during the pedal stroke to eliminate movement and friction between the textile and the rider.

ZeroPressure Waist
A soft, highly elastic waist construction that improves comfort and hold at the waist, minus any pressure or pinching.

GTO S11 Insert
A dual-layer, 21mm construction with additional support beneath the ischial bones.

GTO S11 Insert goldenGate 2.0
The insert is attached at front and rear, letting it float to move with your body rather than against it. New cut-outs on the sides reduce volume and friction throughout the pedal stroke.

KraterCooler
Perforations in the insert’s leading edge draw intercooling air to maintain breathability and a dry, cool microclimate.

WhirlKrater
Perforations strategically distributed throughout the insert, creating a whirlwind of cooling airflow instead of just a unidirectional breeze.
