By analyzing function and mechanical constraints of each part of the frame, our engineers have carefully selected different types of carbon fibre, varying in stiffness and strength, to assemble our frame. These fibres are precisely positioned to increase stiffness, comfort or durability. While Gennix R1 and R2 share similar feel and stiffness, the use of UHM ultra high modulus carbon in key areas reduces the frame weight by more than 10%.
