ABSTRACT:
Lightweight wheel rims for bicycles are formed by pin joints wherein a pin traverses the joint connecting a pair of adjacent ends of a rim member and extend into passages in the rim member on opposite sides of the joint. The improved joint is formed by resilient arms on the pin (or passage) that are resiliently bent or bowed between a pair of spaced contact areas when the pin is forced into the passage and apply pressure resiliently between the pin and the passage wall so the force are applied to inside walls of the passage so that more deflection occurs in the arms as opposed to the rim. In another embodiment of the present invention circumferentially spaced vents are formed leading from the circumferential pin receiving passages to the spoke holes.
