Boardman's C10 Carbon uses a mixture of Toray T1000 and T800 or equivalent fibres. These high modulus fibres have outstanding stiffness to weight ratios, meaning that we can use less material to produce the same level of stiffness compared to lower grade fibres. This in turn means we can shape tubes more dramatically to tune the performance of the frame to suit the type of riding it is designed for. In the ATT range, the use of C10 Carbon facilitates a highly aerodynamic down tube and seat tube, comfort enhancing seat stays, and incredibly stiff chain stays for outstanding power transfer.
