The Assos Mille GTS Bib Shorts S11 Long is a premium endurance bib short designed to balance aerodynamics, compression, and comfort for long-distance riding. The latest S11 generation introduces several key updates, including less restriction at the waist and leg openings, enhanced vertical stability, and improved cooling airflow across the dual-layer insert. The most significant innovation is the rollBar suspension system, adapted from the Racing Series S9, which increases vertical stabilization while allowing a more accommodating waist construction. The butterfly-wrap paneling envelops the muscles, providing micro-adjusted compression that reduces fatigue and enhances aerodynamic performance. Additionally, the updated GTS insert features a dual-layer 13mm construction, adding 4mm of targeted support to the 9mm base of microshock-absorbing foam, ensuring superior comfort over extended rides. Riders can choose between two leg lengths: standard and long (+3cm), allowing for a more tailored fit.

The Mille GTS Bib Shorts S11 Long utilizes Assos' proprietary Volkano textile, offering silky-smooth compression on the inside while providing abrasion resistance, UPF 50+ protection, and a deep matte black finish on the outside. Integrated Mineral Tec technology grants permanent odor control for freshness throughout long rides. The GTS regularFit is situated between a pure endurance fit and a second-skin racingFit, providing a streamlined silhouette that balances aerodynamics with all-day comfort. The patented rollBar design ensures stability by locking the insert in place during weight transfers while sprinting, climbing, and cornering. For optimal performance, the Mille GTS Bib Shorts S11 Long pairs seamlessly with the GTS Jersey and Summer 1/3 GT or Endurance layering systems, delivering the ultimate combination of breathability, support, and aerodynamic efficiency.
