HOPE seat post carbon
In the past, bicycle parts were increasingly defined by the battle between weight, stiffness and durability. Carbon is the material of choice here to meet these requirements. While the HOPE parts traditionally concentrated on CNC-machined aluminum components, it was now time to expand the product portfolio with carbon components. Hope's entry into the carbon market is completely in line with the claim - Made in UK.
Each seat post consists of 24 individual prepregs to ensure a safe and robust unit. The largest share is made up of unidirectional T700 carbon - the standard modulus fiber with high tensile strength - which have been processed to different wall thicknesses.
In addition, strategically positioned layers of 3K carbon fabrics are used. This realizes the necessary strength for the clamping area and a more good-natured breaking behavior in serious accidents.
The 1K outer layer with 2/2 twill weave (oblique, parallel lines) also contributes to these properties and thus offers an extremely smooth surface with excellent aesthetics. Twill weaves have fewer thread crossings and thus result in higher strengths in the laminate.
The ultra-fine adjustment of the seat stay holder can be ordered in the version for round or oval seat stays.
