TRIGON SP102 Ultra Light Carbon Fibre Aero Dynamic Road Bike Seatpost 27.2300mm/350mm Aero-dynamic carbon seat post, designed to reduce air resistance during high-speed riding, comes with 2-bolt micro-adjustment clamps. 27.2*L300 or 350mm, with 60mm adjustable length, weight about 250g(L300mm). 3K matt carbon with VENUS C7 Carbon Composite - High modulus and high strength prepeg raw material, cured at a hightemperature using TRIGON proprietary forming techniques, producing acomposite with unsurpassed fatigue resistance and vibration dampening. FDC - Flex Directional: Careful fiber orientation allows us to tune lateral stiffness verticalcompliance, toughness and dampening properties of the carbon HIPACT - High Pressure Solid Compaction: By using solid inner forms during the curing stage, compared to typicalair-bladder processes, we produce high-pressure compaction which means more consistent products with denser material and minimal voids
