Selle San Marco: The Aspide Carbon FX is for the most discerning riders who are looking for a light weight saddle with high levels of performance. The Aspide Carbon FX is for the most discerning riders who are looking for a light weight saddle with high levels of performance. The new ergonomy with the big hole ensures the best relief and comfort, providing the perfect balance of the support and relief zone in the different positions when pedalling. The waved shape keep the rider in predominantly fixed position whilst also allowing you to push back into the rear of the saddle when climbing.The Unidirectional carbon finish rail (DNA-Carbon - Ø 9,8x7mm), features a greater length rail allowing a wide range of position adjustment. Lighter and more comfortable thanks to our Biofoam padding with extraordinary technological benefits such as the being ultra-lightweight and comfortable.

Superleggera and Carbon FX saddles have this rail.CARBON FIBER REINFORCED SHELLNylon with high properties, enriched with a high proportion of long carbon fibre, in order to reinforce the characteristics of rigidity, stiffness and durability without compromising the weight.BIOFOAMBiodynamic structure that follows the movements of the pelvis during pedalling, guarantees comfort, reduced weight, lasting resistance and ideal support. The “closed cells” surface ensures water is repelled from the padding.MICROFEEL COVERBreathable and hard wearing cover. It is lighter than traditional materials and less deformable. Anti-skid effect with an extraordinary grip on the saddle. Biocompatible material. Carbon fabric touch points accentuate the design and styleNEW ERGONOMYThe perfect balance between the support and relief zone. The big hole helps maintain comfort under pressure and offers day long support and comfort. The central relief zone is long enough to work in all riding positions and the structural stability bridge prevents unwanted flex and twist.
