  • Handlebar height adjustment assembly
    Patent number: 7069812
    Abstract: A height adjustment assembly for a handlebar stem secured to a steer tube of a bicycle is provided. The assembly includes a pair of spacers securable to the steer tube on opposite sides of the handlebar stem that each include a pair of rings engageable with one another to form the spacers. Each ring includes a number of tabs having locking members thereon that are engageable with the locking members on the tabs of the opposed ring of each spacer. By rotating the rings of each spacer with regard to one another, the height of each spacer and the gap between the spacers can be moved upwardly or downwardly along the steer tube to enable the stem to be positioned between the spacers on the steer tube at the desired height.

  • Paired spoke bicycle wheel with optimized rim extrusion and spoke spacing and components thereof
    Patent number: 6679561
    Abstract: A paired spoke bicycle wheel has optimized circumferentially offset spoke spacing which minimizes high stress imposed by overly close spacing and reduces long felt difficulties resulting from out of balance loads of unpaired spokes, the rear wheel additionally having similar spoke angles in a lateral plane while displacing brake surfaces to a centered location when allowing for clearance for a drive cogset.
