Over the last ten years bicycle components have been at the centre of the battle between lightness, stiffness and strength. Carbon has been the material of choice to satisfy these demands. Whilst Hope has traditionally focused on CNC machined components we felt the time was right to expand our quality product range to include carbon composites. Our move into the carbon market is totally consistent with Hope s approach - made in UK.
We didn t rush it! It has taken time to bring in-house, and hone, a new set of skills - ably assisted by leading composites industry professionals and U.K. based materials and equipment suppliers.
HOPE Carbon Seat Post Tech Specs »
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.

Mark: It s been a long and tough transition from primarily working with metallic materials to crossing over to composites, but it has been one which I have relished the challenge. Both materials work hand in hand with one another, and being able to manufacture our own mould tools in house allows us to be highly competitive in the market. It has by no means been without its challenges, and sometimes you just have to throw the rulebook out the window when working with this black-art material. Carbon behaves differently to aluminium, so we basically had to go back to basics and learn about its strengths and weaknesses through extensive testing. It s been an honour working with some of the leading composite experts in the country, and the positive feedback we have had so far is overwhelming with everyones support to help us bring composite manufacture to our UK facility. Hope has invested heavily in this new development over the last couple of years and we are that confident that we have built a dedicated 15,000 square foot composites / R&D centre to our existing factory. It is certainly exciting times ahead for us all.
