More informationInForm saddles are the fruit of the latest biomechanical research to maximize rider performance and comfort; Designed to offer optimal support to riders who adopt an aerodynamic road posture; The integral groove reduces pressure on soft tissues, allowing adopt a posture with greater rotation to generate more power; Two sizes designed to align the saddle with both the female and male bone structure, thus avoiding compression of the soft tissues; Oversized carbon rails that offer lightness and resistance. Specific seatpost adapters are required; Lightweight carbon-reinforced shell that offers a perfect balance between weight, strength and absorbency.
