Assos EQUIPE RSR BOLIDE Bib Short S11 - Black Series

The EQUIPE RSR BOLIDE Bib Short S11 is Assos racing technology refined for sustained high intensity. Built around a tightly compressive leg architecture, the shorts use new Type.959 Kompressor panels to wrap major muscle groups with firm, breathable support that reduces fatigue and improves power transfer. Assos pairs this with softer Type.911 panels across the seat and core to relieve pressure where you need it most while keeping the overall fit sculpted and aerodynamic.

Construction follows Assos AEPD flederMann patterning to create a true second‑skin racing fit with extended leg length to smooth airflow. Integrated anti‑slip yarns provide continuous grip without bulky silicone hems, so the fabric stays locked in place without restricting movement. Raw‑cut edges at the waist reduce constriction and the bib suspender geometry stabilises the shorts through the pedal stroke for consistent chamois contact in aggressive positions.

The RSR S11 Insert is a thermoformed, two‑layer platform with a 9 mm base and targeted 4 mm ultraDistance modules beneath the ischial zones, giving a combined 13 mm shock‑absorbent structure that supports the sit bones in race posture without excess bulk. Perforated zones in the insert and targeted fabric ventilation create a microclimate that channels heat away from the body, making these shorts optimised for warm to hot conditions and long efforts above 21°C.

Overall the EQUIPE RSR BOLIDE S11 is engineered for riders who prioritise race fit, muscle support and ventilation. Its materials and shaping work together to lower aerodynamic drag, reduce muscle vibration on long hard rides and maintain comfort in the saddle with an insert designed specifically for an aggressive riding position.

Key Features

• Type.959 Kompressor panels for high breathability, compression and abrasion resistance around the leg muscles.
• Type.911 seat and core panels that relieve pressure while remaining highly breathable and colourfast.
• RSR S11 Insert - Twin 13 thermoformed two‑layer chamois: 9 mm base plus 4 mm ischial modules for targeted shock absorption.
• AEPD flederMann racing fit patterning for a second‑skin aerodynamic profile with extended leg length.
• Electrified Grip anti‑slip yarns integrated into the fabric to keep legs securely in place without silicone bands.
• UPF 50+ protection in principal body fabrics and perforated insert zones for ventilated cooling.

Ideal For

• Road racers and time trialists seeking a second‑skin, aerodynamic short for high intensity events.
• Fast group rides and long-breakaway efforts in warm to hot conditions where breathability and sustained compression matter.
• Riders who prefer a structured, performance chamois engineered for aggressive saddle positions.
