Abstract
The invention disclosed herein is a durable, lightweight, bicycle dropout-fitting design for use on high strength fiber reinforced composite frames and forks of competition bicycles. The invention provides improved fatigue and impact resistance compared to prior art designs. The invention is configured to make maximum use of modern cold metal forming methods to produce the connecting part and adhesive bonding and/or co-curing methods to join the part to the primary structure. The superior structural performance of the invention is provided by a unique geometry that efficiently utilizes the material properties of the part to maximize the rigidity and strength of the joint.
