ABSTRACT:
A method for manufacturing a fiber-reinforce plastic bicycle handlebar by an injection molding process. The resulting handlebar approximates the exterior appearance, configuration and attachment means of traditional prior art handle bars for all terrain bicycles or mountain bikes, while providing a handlebar that is light weight, strong, durable, shock absorbing and cost efficient to manufacture. A manufacturing method for manufacturing the handlebar includes injection of thermoplastic material into a gap located between a core and cavity.
