Selle San Marco: A classic reinvented with the innovative Bow Rail System for off-road adventures. This is the new Regal Short Open-Fit. Made using a patented design, the Bow Rail System is fixed to the saddle's rearmost part, allowing the shell to be flexible and work with your body while on rough gravel rides and long bikepacking trips. Adding shock absorbers allows the Regal Short to flex much more than traditional saddles. 40 years on from its first introduction, and finished with carbon rails and an Open-Fit design, the Regal Short is yet again one of the most innovative saddles on the market. Materials and Shapes CFX - Carbon Fiber Superlight full carbon fiber rails with oval section (9,8 mm x 7 mm) with PATENTED DNA (Dynamic Node Action) technology which prevents twisting and keeps the front of the saddle narrow for great pedalling freedom. It makes the Carbon fiber rails even stiffer and, give to the central geometry a longer section to ensure more extensive saddle adjustment. This Rails is used on Superleggera and Carbon FX saddles. An adaptor might be required with some seat posts. Carbon Fiber Reinforced Shell High-performance nylon, enhanced with carbon fibres, built with variable thickness, reinforcements by ribs and bridges, which enhance the rigidity with ergonomy and durability characteristics, without affecting weight to the shell. Texfeel Cover Created to give the texture and feel of fabric but with the classic comfort of a traditional cover. Texfeel is easy to clean, nice to touch, and keeps your saddle looking its best for longer. Biofoam Padding Biodynamic low density foam with variable thickness structure that follows the movements of the pelvis when pedalling, for guaranteed comfort, light weight, long lasting resistance and ideal support.
