The ASSOS MILLE GTS Bib Shorts S11 Long are long-distance endurance bib shorts engineered to balance aerodynamic performance, supportive compression, and lasting comfort. The S11 generation introduces a less restrictive waist and leg opening, increased vertical stability, and improved cooling airflow throughout the insert.
Butterfly-wrap panelling surrounds the leg muscles with targeted, fatigue-reducing compression, while the rollBar suspension system stabilises the insert during sprints, climbs, and corners. The dual-layer GTS S11 Insert combines a 9mm base with 4mm of targeted support, providing 13mm of shock absorption and vibration damping for long days in the saddle.
Key features
Product specifications
GTS S11 Insert
The dual-layer Shock-Absorb Damping System Twin combines fast-drying, high-density foams to absorb impacts and reduce micro-vibrations. The perforated 3D Waffle construction reduces weight and increases breathability, while kraterCooler and whirlKrater perforations circulate cooling air throughout the insert. The goldenGate 2.0 construction allows the insert to move naturally with the body, reducing friction throughout the pedal stroke.
Composition
Size & fit
The GTS regularFit sits between a pure endurance fit and a second-skin racing fit, combining streamlined aerodynamics with long-distance comfort. This Long version features 3cm of additional leg length compared with the standard model.
Care & washing instructions
Machine wash cold on a gentle cycle with similar colours. Do not bleach, tumble dry, iron, or dry clean. Air dry to preserve the fabric’s elasticity, compression, and insert performance.
