1. A shaped preform component for a spoke portion of a composite wheel, the shaped preform comprising:
an elongate body configured to be located in the spoke portion of a composite wheel,
wherein the shaped preform component is formed from a cured composite fibre material having a compressibility of <2% volumetric under moulding conditions of 50 bar hydrostatic pressure and a temperature of 60 to 150° C.,
and wherein the density of the cured composite fibre material is selected to form a counterbalance mass for a mass addition to the composite wheel.
