To optimally support the large muscle groups, the new **Type.959Kompressor** is used on the legs, while the seat area and core are relieved with **Type.911**. The result is a second skin with stable **360° support**, noticeable **compression** and improved breathability for long, fast rides in summer heat. The new **RSR S11 Insert** dampens micro-shocks with low volume and directs cooling air specifically through the seat area. Thanks to the ultra-elastic textiles, Assos was able to eliminate the previous rollBar system without losing stability, and the leg length is aerodynamically longer. Available in six sizes from XS to 2XL and developed in Switzerland for uncompromising performance. - New **Type.959Kompressor** on the legs: maximum **compression**, higher abrasion resistance and integrated **ELECTRIFIED Grip** against slipping. - **Type.911** in the seat/core area for pressure relief on sensitive zones. - **RSR S11 Insert** with **Shock-Absorb Damping System Twin 13**: 9mm base foam plus 4mm ultraDistance modules under the sit bones. - Ventilation through **kraterCooler** and **whirlKrater** for an intense, cooling airflow. - **X-Frame** carrier system stabilises lower back and insert; **goldenGate 2.0** lets the seat work with the body. - **UPF 50+** for both main textiles; aerodynamically longer leg in **racingFit**. ## Technical Details and Features The **AEDP flederMann** cut is an aggressive **racingFit** with second-skin character, developed with feedback from the WorldTour and designed for maximum efficiency in riding position. The targeted **Endurance Compression** arranges the panels so that the compression effect around thighs and hips works evenly and fatigue-inhibiting. The **Type.959Kompressor** gives the RSR S11 its tight but flexible fit and prevents the need for classic silicone grippers on the thigh with woven-in fibres. At the same time, **Type.911** on the buttocks provides noticeably less pressure without affecting stability. The **RSR S11 Insert** combines the dampening **Twin 13** platform with **goldenGate 2.0**, so the insert is fixed front and back but "floats" freely at the sides. The perforated zones **kraterCooler** and **whirlKrater** increase air circulation and keep the microclimate noticeably drier and cooler. ## Applications and Benefits Designed for race days, marathon events and long training blocks in heat, the RSR S11 shows its strengths particularly at high cadence and on rough asphalt. The stable **compression** reduces micro-vibrations and helps keep the muscles efficient over hours, while the open ventilation regulates the climate at the seat. The longer leg finish sits quietly, supports aerodynamics and harmonises with light summer socks and leg warmers. The S11 generation stands for more breathability and lower weight compared to the S9 era, which independent tests on the RS-S11 platform also highlight. Combined with **UPF 50+** and the quick-drying **Mineral Tec Surface**, this creates racing shorts that convince in the Swiss summer season from interval training to ultra-distance. ## Technical Details and Features The material composition underlines the performance approach: Front Main Fabric 68% polyamide, 31% elastane, 1% polyester; Front Insert 80% polyamide, 20% elastane; Padding Insert 85% polyester, 15% elastane. Both main textiles offer **UPF 50+** and remain deep black even when stretched, which is particularly advantageous in the sun. The **X-Frame** straps distribute the pull evenly across the back, keep the insert quiet and prevent sagging during sprints or tempo changes. Because the **ELECTRIFIED Grip** is already in the fabric, the leg finish is pleasantly clean without additional silicone and stays reliably in place even with lots of sweat or hot conditions. For riders who ride longer aero positions, the **RSR S11 Insert** delivers the required dampening with low volume – ideal when every gram and every watt counts. Available in six sizes from XS to 2XL for a precise fit in **racingFit**. ## Variants - 11.10.291.18.2XL: in stock - 11.10.291.18.XS: in stock - 11.10.291.18.S: in stock - 11.10.291.18.XL: in stock - 11.10.291.18.L: in stock - 11.10.291.18.M: in stock --- Source: https://kilometro.ch/en/products/shorts-664/equipe-rsr-bib-shorts-s11-558
