The ultra endurance cycling bib shorts represent the most advanced expression of road racing technology, designed for those who face long races, high speeds, and extreme aerodynamic positions. Assos Equipe RSR Bolide S11 – Bib Shorts are developed for pure competition and for cyclists who demand decisive muscle support, total stability, and optimal comfort management even after many hours in the saddle. These ultra endurance cycling bib shorts are made for the road and for high-intensity competitive use.

The Kompressor fabric, the most compressive in the range, wraps the main leg muscle groups with structured pressure, helping to reduce fatigue caused by continuous micro-vibrations from the asphalt. The targeted compression supports the muscles during prolonged pushing phases, maintaining a feeling of compactness and control during sprints, time trials, and long-distance races. In more sensitive areas, such as the saddle and core, Type.911 fabric is used, which is less compressive but highly elastic, to relieve pressure and improve comfort on extended rides.

The construction combines compressive and ultra-elastic materials to ensure 360-degree stability without the need for additional support structures, offering a clean and snug fit. The raw-cut waist eliminates constrictions and pressure points, promoting a feeling of continuity between body and technical garment. The RSR S11 Insert chamois integrates low-volume padding with high ventilation and additional shock-absorbing modules under the sit bones, designed to offer effective support in the most aggressive riding positions.

Designed for male cyclists focused on road competition and ultra-endurance races, the Assos Equipe RSR Bolide S11 ultra endurance cycling bib shorts combine advanced compression, second-skin aerodynamics, and evolved comfort, making them a technical choice for those who want to maximize performance and stability in every phase of the race.
