The Selle San Marco Shortfit Allroad Supercomfort Racing is engineered for long rides, endurance gravel and demanding terrain. Built around the proven Shortfit geometry and waved shape, it is designed to reduce fatigue over time while maintaining comfort, stability and control across rough surfaces. The Supercomfort system uses integrated gel to improve pressure distribution and vibration damping, working with the Bow Rail System and shell-integrated Shock Absorbers to smooth out repeated impacts from gravel, compact dirt and broken roads. Xsilite rails complete the Racing build, providing lightweight strength and responsiveness for long-distance performance. Features • Shortfit geometry designed for comfort, support and efficient positioning on long rides • Waved shape helps improve rider stability and control across gravel and mixed terrain • Supercomfort system uses thicker Biofoam Plus padding with variable density for improved comfort and posture support • Integrated gel improves pressure distribution by reducing peak loads on contact areas, while also helping absorb vibration from rough roads and gravel surfaces • Bow Rail System allows the shell to pivot around the rails, helping absorb micro-impacts and vibration without dulling pedalling efficiency • Shell-integrated Shock Absorbers help filter high-frequency vibration from gravel, compact dirt and broken roads • Xsilite rails provide lightweight strength and responsiveness for long-distance and technical riding • Carbon fibre reinforced shell uses high-performance nylon enhanced with carbon fibres, with variable thickness and structural ribs designed to improve rigidity, ergonomics and durability without adding unnecessary weight • Microfeel cover uses a durable microfibre material that is abrasion resistant, weather resistant, breathable, easy to clean and built for long-lasting use • Biofoam padding uses a biodynamic, low-density foam with variable thickness that follows the movement of the pelvis while pedalling, helping maintain comfort, light weight, support and long-term resistance • Designed for endurance gravel, bikepacking and demanding all-road riding Specifications Intended Use: Gravel & Bikepacking Size Options: S3, L3 Dimensions: S3 140 x 256mm / L3 155 x 260mm Weight: S3 242g / L3 250g Weight Tolerance: ±8% Rail: Racing - Xsilite Shell: Carbon fibre reinforced nylon Cover: Microfeel Padding: Biofoam Plus with integrated gel Profile: Waved Cut-Out: Superflow
