Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.

A method for manufacturing a fiber formed body includes forming a fiber board into a predetermined outer shape while forming a pattern on an outer surface of the fiber board by compressing the fiber board, a forming at least one positioning member by compressing the fiber board, and positioning, relative to a cutoff device, the fiber board using the positioning member, and cutting off a cutoff target part of the fiber board using the cutoff device. In the method for manufacturing the fiber formed body, formation of the pattern during the forming of the outer shape and formation of the positioning member during the forming of the positioning member are simultaneously performed.
