The Dusters are a Flat-Forward, race ready proven design that allow hours in the saddle. Using a Light-Weight Nylon Glass Fibre base and D2 Edge Flex System, this dual injected base features a soft, rubberized compound along the outer edges of the saddle which allows flex through each pedal stroke, while keeping the centre stiff for ultimate power transfer. Engineered with a snag less rear and nose platform, the Dusters are constructed with a mid-density EVA or Light Weight PU foam and designed for those who desire less pelvis rotation and more mobility. Ergonomically designed with a tip to tail peri-canal for added comfort relief makes the Duster an ultimate tool for numerous riding disciplines. The globally patented I-Beam Technology is the original seat-to-post connection, featuring a monorail design which is proprietary to the SDG brand, allowing the ultimate strength to weight ratio with more fore and aft adjustment capabilities than most traditional rails. All I-Beam Dusters use the Flex-Cavity I-Beam which suspends the monorail for added comfort and shock absorption. Utilizing the Peri-Canal which enables fore and aft movement without pressure in the perineum region. Flat and squared off nose to extend ease of movement to the front of the saddle.
