# EQUIPE RSR BOLIDE Jersey S11 > Assos EQUIPE RSR BOLIDE Jersey S11 - Aero race jersey, wind tunnel-verified, racingFit, ultralight & highly breathable for hot race days - Price: 341.00 CHF - Brand: Assos - Category: Jerseys - Availability: in stock - SKU: 11.20.439.58.M, 11.20.439.58.XS, 11.20.439.58.2XL, 11.20.439.58.XL, 11.20.439.58.L, 11.20.439.58.S ## EQUIPE RSR BOLIDE Jersey S11 The EQUIPE RSR BOLIDE Jersey S11 is the fastest aero race jersey in the ASSOS portfolio, verified in the **ASSOS AeroScience** development environment in the **wind tunnel**. At its core, the front features the new **Hawk‑01** fabric, whose open diamond structure calms incoming airflow, while **Eagle‑01** at the sleeves and shoulders actively channels airflow through pronounced wind channels. The fit follows the **racingFit AEPD** with a nearly seamless surface optimised for high-speed riding – validated with feedback from the **WorldTour** and Swiss Cycling. Available in the White Series and in 6 sizes (XS–2XL), this race jersey is built for maximum speed and cooling in intense summer conditions. - Developed with **ASSOS AeroScience** and wind tunnel-tested – focused on minimising aerodynamic drag - Front panel in **Hawk‑01** for drag-reducing diamond structure, sleeves/shoulders in **Eagle‑01** for directed airflow - Ultra-lightweight back panel in **Hill Rombo** for high breathability at race pace - **Bonded** shoulder seams and aerodynamically aligned **Raglan sleeves** for a smooth, disruption-free surface - Three secure **zeroSeam Pockets** with a clean finish for safely stowing nutrition and your phone - **racingFit AEPD**: compressive, second-skin fit, optimised for aggressive race positions - **Clima Code Summer (1/3)**, colour White Series, available in 6 sizes (XS–2XL) ## Technical Details and Features The fabric architecture is consistently designed for laminar airflow: **Hawk‑01** at the torso breaks up turbulence from frontal airflow, while **Eagle‑01** channels air parallel to the surface across the upper arms and shoulder girdle. The **bonded** transitions across the shoulders eliminate the raised edges of traditional flatlock seams, reducing potential points of aerodynamic disruption. ASSOS deliberately leaves the fabrics **unflattened** (preserving the 3D structure) so that aero properties and **cooling performance** hold up under race conditions. At the back, **Hill Rombo** promotes moisture transfer, while the **zeroSeam Pockets** keep your essentials secure without compromising aerodynamics. The stitched details and panel-based **AEPD** construction are tailored to the position "in the drops", so every watt counts. ## Use Cases and Benefits The BOLIDE Jersey S11 comes into its own wherever speed and consistency matter: on the road bike in criterium laps, during fast club rides on the Zürichsee circuit, or at hot mountain races in the Valais. Compared to conventional jerseys, the AeroScience construction reduces **surface turbulence**, lowering aerodynamic drag and improving efficiency at high speeds. Thanks to the cooling, highly breathable fabrics, performance stays consistent even in summer heat without restricting breathing. If you're after the advantages of a speed suit but want the flexibility of a full-zip jersey, this is the race-ready solution distilled to its essentials – with secure pockets built for competition. The specialist press regularly confirms the performance focus of the S11 series for jerseys built for hard riding. ## Fit, Sizing and System Thinking The **racingFit AEPD** is athletically compressive, fits like a second skin, and is designed for aggressive positions; the **Raglan sleeves** are aligned so that the **Eagle‑01** channels sit optimally in the airstream. The model is available in 6 sizes from **XS to 2XL** and as part of the **White Series** within the speed-focused BOLIDE capsule. Designed as a system, the jersey pairs perfectly with the **EQUIPE RSR BOLIDE Bib Shorts S11** as well as **RSR Speed Gloves** and **RSR BOLIDE Socks** for a coordinated aero advantage across your entire body. ASSOS backs the product with a **2-year warranty** and a crash replacement policy, offering additional peace of mind – especially for high-mileage riders in Switzerland. ## Variants - 11.20.439.58.M: in stock - 11.20.439.58.XS: in stock - 11.20.439.58.2XL: in stock - 11.20.439.58.XL: in stock - 11.20.439.58.L: in stock - 11.20.439.58.S: in stock --- Source: https://kilometro.ch/en/products/jerseys-663/equipe-rsr-bolide-jersey-s11-1128
