The Assos Equipe RSR S11 Cycling Bib Shorts are the pinnacle of racing technology, combining Assos' lightest, most compressive textiles with aggressive second-skin aerodynamics. Engineered for ultra-endurance races at unrelenting intensity.

Behind the Product

More breathable, more compressive, more aerodynamic – the Assos EQUIPE RSR S11 replaces the RSR SUPERLÉGER S9 as the most advanced Racing Series short in ASSOS history. The new textile wrapping the large muscle groups of the legs is our most compressive Kompressor textile to date, providing firm support to reduce the accumulated fatigue from micro-vibrations during hours of high-intensity riding.

The seat and core are wrapped in the less compressive Type.911, which is the main textile of the RS S11 and R S11 bib shorts, employed here to relieve pressure on sensitive areas. The combination of compressive, ultra-elastic textiles allowed us to remove the rollBar while maintaining 360-degree stability, and the raw-cut waist eliminates restriction. The new RSR S11 insert incorporates the same low-volume, microshock-absorbing comfort and hyper cooling airflow of the RS S11 insert, but it includes additional shock-absorbing modules beneath the ischial bones, oriented for maximum effect in aggressive riding positions.

• When/How to Use These Shorts - Pair with the RSR S11 Jersey and Summer 1/3 RSR layering system for the longest rides at the highest intensity in the hottest conditions.
• Featured Fabrics - all new Type .959Kompressor is a proprietary woven textile that's more breathable, more cooling, and more compressive than previous Kompressor materials.
• .959 Kompressor Fabric protects the rider with increased abrasion resistance, and its integrated anti-slip properties eliminate shifting and friction.
• Seat and core are wrapped in the Type.911 textile that defines.the rest of the Assos Racing Series.
• UPF 50+
• Construction/Fit - The AEDP flederMann pattern is a second-skin, aerodynamic racing fit designed with WorldTour feedback and proven WorldTour results.  Micro-adjusted shaping wraps the large muscles with compressive support in a longer, more aerodynamic leg length.
• Enduance Compression - Muscle-wrapping support that reduces fatigue during multi-hour, high-intensity rides.  The textile panels are arranged to maximize compressive benefits.
• Electrified Grip - Integrated anti-slip yarns are woven directly into the Kompressor textile, providing frictionless, un-interrupted grip around the thigh.
• RSR S11 Insert - a two-layer racing platform of 9mm foam supplemented with 4mm ultraDistance inserts under the ischial bones.  Thermoformed shaping eliminates ridges and irritation.
• KraterCooler - Perforations in the insert's leading edge draw intercooling air to maintain breathability and a dry, cool microclimate.
• whirlKrater - Perforations distributed throughout the insert create a whirlwind of cooling airflow instead of just a unidirectional breeze.
• Mineral Tec Surface - A soft, ultrasmooth coversheet that reduces friction and irritation while promoting comfort with quick-drying properties and permanent odorControl.
• goldenGate 2.0 - Insert is attached at front and rear with floating sides and center, letting it move with your body rather than against it.  New cut-outs on the sides reduce volume and friction throughout the pedal stroke.
