Assos Rapidfire Chronosuit S11
When looking to gain an edge over your competitors, the Assos RS Rapidfire Chronosuit S11 is a cutting-edge skinsuit developed for elite cyclists pushing themselves faster and further. Whether competing in time trials or track events this speedsuit features all-new textiles like Hawk-01 and Eagle-01, deployed to reduce drag and weight while offering compression tailored to high-intensity racing. Hawk-01 on the upper body features a rhombus construction to minimize surface turbulence, while Eagle-01 on the sleeves and lower back uses wind-stripe channels to streamline airflow. The legs feature the highly compressive Type.959Kompressor textile, which combines breathability, cooling, and abrasion resistance to withstand the demands of competitive cycling. Thoughtfully added details, such as a front radio pocket and number pocket, enhance functionality, making this suit a top choice for professionals.
Designed with input from World Tour athletes, the RS Rapidfire offers an exceptionally aerodynamic fit with maximum compressive support. The suit’s leg cut is longer than typical Assos racing fits, optimising muscle support and airflow across the entire body. Its UPF 50+ fabric provides additional sun protection, and the full-length front zip allows quick adjustments during warm-ups or for mid-race ventilation.
RS Chrono S11 Seat Pad
The RS Chrono S11 seat pad is engineered specifically for racing, made with lightweight materials and a streamlined 8mm single-layer Shock-Absorb Damping System Mono that reduces bulk without sacrificing support. Designed for high performance, it features thermoformed shaping to prevent ridges and irritation, ensuring a smooth fit. The pad’s patented 3D Waffle technology adds three layers of perforated foam for superior breathability and reduced weight, enhancing airflow for comfort during intense efforts.
With the innovative goldenGate 2.0 construction, the insert attaches at the front and rear, allowing the pad to "float" with body movements. This reduces friction and pressure across the pedal stroke, making it a top choice for racers focused on speed and comfort.

About Assos
Swiss precision. Half a century of obsession.
Assos of Switzerland was founded in 1976 by Toni Maier-Moussa with a single ambition: reinvent cycling apparel from the inside out. The Lycra cycling short, modern bibs, the chamois as we know it — all began here. Half a century later, the obsession with precision and ride feel hasn't moved an inch.
Assos still designs and engineers every piece in Switzerland. The brand operates its own laboratory, its own development pool of test riders, and its own assembly line for the most demanding garments in the range.
