A bicycle wheel rim design with high safety margin and optimized strength-to-weight is described. The rim provides a tire bead supporting platform which defines a circumferential bead seat with minimum bead seat diameter equal to the standard tire bead diameter defined for a particular size of tire. Each tire bead seat defined along the rim circumference is comprised by a pair of circumferential ridges. The circumferential ridges comprise the external sidewalls of the rim and do not include tire bead hook features, and are of optimized sidewall thickness to add load strength and lateral stiffness, and resist crushing from impact. The interior ridges are increased diameter towards the medial plane of the rim to a value greater than the specified tire bead diameter. Given this geometry, the left lateral and right lateral of each tire bead is safely constrained within the defined bead seats under a wide variety of uses.
A bicycle rim comprising a wheel which features automatic axial centering of its associated mounted tire and bead supporting surface (bead seat) which constrains a beaded tire. Each bead seat is comprised of a first straight sidewall and a second straight sidewall wherein said bicycle rim does not implement bead hooks. The tire beads are retained and restrained next to the sidewalls adjacent to the bead seat. The tire beads allow sufficient rim sidewall clearance such that tire installation and removal over the rim sidewalls is easily achieved by the user during mounting and dismounting operations of the tire.
