The Bioaktive Trekking Biofoam Open-Fit saddle is designed for riders who enjoy relaxed cycling adventures and touring freedom. Perfect for trekking and city riding, it combines ergonomic design with Selle San Marco’s renowned Italian craftsmanship to provide long-lasting comfort and durability. The biodynamic Biofoam structure adapts naturally to pelvic movement during pedalling, offering reduced weight and enhanced resilience. The Open-Fit design, developed through anatomical studies, ensures excellent pressure relief in the perineal area, promoting comfort even on extended rides. Choose the Large version for leisurely cycling or the Small version for longer, more performance-oriented rides. Bioaktive is a distinguished line of anatomically designed saddles developed through Selle San Marco’s rich heritage and expertise — crafting handmade saddles in Italy since 1935. Each model combines premium materials, advanced design, and ergonomic precision to match specific riding styles. The Bioaktive range simplifies selection with three categories: Sportive, Trekking, and City. Which kind of rider are you? If you prefer shorter, occasional rides, the Large saddle ensures plush comfort. For frequent or longer rides, the Small saddle provides firmer support and better pedalling efficiency.
