Each seat-post employs 24 individual plies of carbon, pre-impregnated with a highly toughened epoxy resin system, designed to ensure a safe and rugged unit. The bulk of the laminate comprises Unidirectional T700 fibre, the highest strength Standard Modulus fibre available. (Unidirectional fibres provide the maximum tensile strength and stiffness with minimum weight.) This is combined with strategically positioned plies of 3K twill woven fabric, adding hoop strength to resist clamping forces and mitigating failure mode in the event of serious crash damage. The 1K 2x2 twill weave fabric outer ply, also contributes in this respect together with a super smooth finish and striking visual aesthetic.Key Features:100% designed, tested and manufactured in Barnoldswick, EnglandSmooth internal surface finish removes any unnecessary resin rich areas to minimise weightVarying wall sections to optimise weight and areas of high stress concentrationsSame ultra-fine seat rail adjustment as tried and pr
