Abstract: A seat mounting assembly include a tilt adjustment system wherein the angle of a link on which saddle is mounted may be adjusted via a saddle tilt adjusting mechanism that interconnects base and link members at a position spaced from a moveable connection between the link and base member. The tilt adjusting mechanism is formed by a position adjusting element for adjusting the relative position of the link and base and an independent locking element that unlocks the adjusting mechanism independent of position adjusting element so that the position adjusting element may be then be independently adjusted to adjust the relative position of base and link members from a relative position preset by the adjustment mechanism so that the adjustment commences from the location of the previous adjustment thereby facilitating seat adjustment and accurate repositioning.

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.
