EQUIPE RSR BOLIDE Bib Shorts S11

Assos EQUIPE RSR BOLIDE Bib Shorts S11

The EQUIPE RSR BOLIDE Bib Shorts S11 are designed for uncompromising race performance and combine Assos's lightest, most compressive fabrics with aggressive second-skin aerodynamics. On the legs, the new Type.959Kompressor fabric provides noticeable support and reduces fatigue from micro-vibrations, while Type.911 in the seat and core area minimizes pressure on sensitive zones. The redesigned RSR S11 Insert uses targeted cushioning modules beneath the sit bones and maximizes air exchange for a cool microclimate during high-intensity efforts. A raw-cut waistband and the AEPD flederMann construction based on WorldTour feedback stabilize the shorts all around without restricting freedom of movement. Both main fabrics offer UPF 50+ and are optimized for maximum breathability, ideal for racing in heat and during long efforts. Available in six sizes from XS to 2XL, in the blackSeries colorway.

• Type.959Kompressor on the legs: highly compressive, breathable woven fabric with enhanced abrasion resistance and integrated anti-slip properties.
• Type.911 on the seat and around the midsection: soft, compressive, ultra-airy carrier material that stays deep black even when stretched.
• RSR S11 Insert with Shock-Absorb Damping System Twin 13, whirlKrater perforations, kraterCooler, and goldenGate 2.0 for efficient cushioning, cooling, and friction reduction.
• ELECTRIFIED Grip: anti-slip yarns woven into the Kompressor fabric for consistent hold without friction.
• X-Frame strap system stabilizes the insert and back panel during intense accelerations; rollBar was eliminated thanks to the elastic-compressive material combination.
• racingFit with micro-adjusted fit and aerodynamically extended leg length; UPF 50+ protection on main fabrics.

Technical Details and Features

The Type.959Kompressor delivers a rare balance of firm compression, high cooling performance, and low friction, which measurably relieves muscles over hours. Around the core and seat, Type.911 provides sensitive stability to reduce pressure peaks in aggressive race positions and keep the pedaling motion natural. The RSR S11 Insert combines a 9mm racing platform with additional 4mm ultra-distance modules beneath the sit bones; whirlKrater perforations create a swirling airflow, while kraterCooler directs fresh air precisely where needed. Thanks to goldenGate 2.0, the pad can move laterally with hip movement and minimize friction, while the Thermoform contour eliminates hard edges. The ELECTRIFIED Grip yarns provide a stable leg closure without traditional silicone grippers, and the raw-cut waistband supports the torso without pinching. The AEPD flederMann cut fits like a second skin and was refined with WorldTour feedback.

Applications and Benefits

These bibs are made for ultra-endurance races, fast training sessions on hot summer days, and race situations where every watt counts—from Alpine passes to time trial sections in the lowlands. The strong compression reduces micro-vibrations on rough asphalt, which noticeably protects muscles during long Swiss road cycling stages. The aerodynamically extended leg length and racingFit minimize flapping and support a low, efficient position. Within the RSR S11 family, the application range is clearly focused on warm conditions, reflected in maximum breathability and quick drying. Anyone familiar with a similarly race-oriented S11 fit will find the same precise, body-hugging contour here, which was praised in independent tests of the S11 generation for Type.911 and the new fit. For Swiss racers, this means: consistent cooling on climbs, stable hold in sprints, and comfort even when the speedometer stays in the red zone for hours.

Additional Relevant Information

The material composition is performance-focused: legs 69% polyamide / 31% elastane, insert zones in front/back/crotch 80% polyamide / 20% elastane, pad cover layer 85% polyester / 15% elastane. Both main fabrics offer UPF 50+, which provides additional protection in high-summer conditions without restricting breathability. The combination of X-Frame straps and the eliminated rollBar reduces visible strap construction while maintaining 360° stability of the pad during intense sprints. For a complete race setup, the manufacturer recommends pairing with RSR S11 tops and Summer 1/3 layering in very warm weather. Six size options make it easier to choose the right fit for Swiss athletes who alternate between long Alpine climbs and flat tempo sections.
