Assos Equipe RSR Bib Shorts S11

The Assos Equipe RSR Bib Shorts S11 represent the pinnacle of cycling performance apparel — engineered for racers, ultra‑endurance athletes, and riders who demand maximum compression, aerodynamics, and muscle support during long, high‑intensity efforts. These bib shorts are part of Assos’ elite racing lineup, combining cutting‑edge textiles and ergonomic design to help you push harder and stay fresher mile after mile.

World‑Class Performance Design

Built with Type.959 Kompressor textile, these shorts deliver firm, breathable compression that supports large leg muscles while reducing fatigue caused by micro‑vibrations under load. The advanced textile also offers abrasion resistance, integrated anti‑slip grip, and UPF 50+ protection — all in a sleek second‑skin fit that minimizes drag and enhances pedaling efficiency.

Around the seat and core, the Equipe RSR uses the Type.911 textile, a softer, ultrabreathable material that relieves pressure on sensitive areas while maintaining stability and airflow. The combination of these premium fabrics lets Assos eliminate traditional bulky features (like rollBars) while preserving 360° stability and comfort.

Advanced Insert Technology

At the heart of the bib shorts is the RSR S11 Seat Pad, featuring a dual‑layer cushioning system with 9 mm of shock‑absorbing foam and extra 4 mm ultraDistance modules under the ischial bones. Thermoformed shaping eliminates ridges and irritation, while kraterCooler and whirlKrater perforations enhance airflow across the pad for superior ventilation and comfort on long rides.

The bib straps employ an X‑Frame design that limits sag in the lower back and stabilizes the pad and body panels during intense efforts, keeping everything locked in place when you need it most.
