Hollow composite bicycle component and method of manufacturing the hollow composite bicycle component

A hollow bicycle component comprising:

• a composite laminate comprising:
• a hollow container made of a first polymer-based material;
• a layer of a second polymer-based material disposed on the hollow container;
• and
• a layer of a composite material disposed on the layer of the second polymer-based material, the composite material including a matrix of a third polymer-based material and fibers of a reinforcing material.

A method for manufacturing a hollow bicycle component, the method comprising:

• forming a hollow container, the hollow container being made of a first polymer-based material;
• preparing a core material mixture, the core material mixture including a salt, expandable microspheres, or a combination thereof;
• filling the hollow container with the core material mixture;
• forming a layup pattern, forming the layup pattern comprising positioning at least a layer of a second polymer-based material and a layer of a composite material on the hollow container;
• forming a composite laminate including the hollow container, the layer of the second polymer-based material, and the layer of the composite material;
• and
• dissolving, removing, or dissolving and removing the core material mixture.
