Abstract:
1. A bicycle wheel rim, comprising: a base portion including a proximal surface having a portion engageable with a spoke member and an opposing distal surface having flat bead seats engageable with a surface of a tire; and two opposing sidewalls extending from the base portion, wherein each of the sidewalls has an inner surface profile that matches a contour of an engaging surface of the tire along the entire sidewall, further wherein the profiles respectively have an inner surface that extends inwardly and is curved at an intersection point of the flat bead seats with the two opposing sidewalls, and such that a bulbous bead lock portion is absent from a distal region of each sidewall so that a thickness of the sidewalls is not increased from where the sidewalls begin to extend inwardly to a point of each sidewall most distal the bead seats, wherein the bead seats are horizontally disposed with respect to an axial direction of the rim so that when the tire is mounted, beads of the tire are placed between the flat bead seats and the sidewalls to provide a ball and socket fit, and wherein the sidewalls extend from intersections of the proximal surface and the distal surface, and wherein the point of each of the sidewalls most distal the flat bead seats respectively extends no further than 0.200 inches above the flat bead seats of the distal surface of the rim.
