# EQUIPE RSR BOLIDE Bib Shorts S11 > Assos EQUIPE RSR BOLIDE Bib Shorts S11 - racing bib with strong compression, aerodynamic second-skin fit, RSR S11 chamois and UPF50+ for warm-weather rides - Price: 341.00 CHF - Brand: Assos - Category: Shorts - Availability: in stock - SKU: 11.10.325.18.L, 11.10.325.18.XL, 11.10.325.18.S, 11.10.325.18.M, 11.10.325.18.XS, 11.10.325.18.2XL ## 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. ## Variants - 11.10.325.18.L: in stock - 11.10.325.18.XL: in stock - 11.10.325.18.S: in stock - 11.10.325.18.M: in stock - 11.10.325.18.XS: in stock - 11.10.325.18.2XL: in stock --- Source: https://kilometro.ch/en/products/shorts-664/equipe-rsr-bolide-bib-shorts-s11-926
