Assos MILLE GTS Bib Shorts S11 (long) - Black Series

The MILLE GTS Bib Shorts S11 Long are Assos’s interpretation of a long‑distance, everyday performance short. Positioned between a pure endurance fit and a second‑skin racing cut, the GTS regular fit in the S11 generation aims to deliver sustained comfort over hours in the saddle while preserving a clean, aerodynamic profile. The long leg option adds approximately 3 cm of fabric at the hem for riders who prefer additional thigh coverage.

Construction focuses on layered support and airflow. The GTS S11 insert uses a twin‑layer 13 mm construction that pairs a shock‑absorbing base with a damping layer to reduce micro‑vibration and road buzz. Multiple perforation systems - including 3D Waffle, kraterCooler and whirlKrater - increase ventilation through the pad so the microclimate stays drier and cooler on longer efforts. goldenGate 2.0 attachment lets the insert move with the body, reducing friction through the pedal stroke, while the kukuPenthouse front panel removes pressure and improves cooling at the front of the saddle area.

Fit and stability are refined with the rollBar suspension system, a bracing design adapted from Assos’s Racing line that stabilizes the insert and helps keep it correctly positioned during sprints, climbs and technical changes of weight. The zeroPressure waist reduces constriction at the midriff for a more comfortable hold without pinching, and PILtec Plug‑In microdot silicone at the leg openings gives discreet grip when conditions are wet. Main fabrics include Volkano face‑in compression yarns that balance muscle support with abrasion resistance and quick drying performance.

Together these elements make the MILLE GTS S11 Long a practical choice for riders who cover varied terrain and durations but want a thoughtfully engineered short that emphasises breathability, sustained shock management and a stable, secure fit. Pair with Assos GTS jerseys and summer layering for consistent thermal balance and airflow on longer outings.
