A wheel of a bicycle has a standard or undersized hub mounted on a wide rim using offset spokes in order to correspondingly offset the hub and a rear cog or pulley to one side. The offset hub provides chain or belt clearance between a chain or belt, a tire and a rim edge of the wide rim. An undersized tire may be mounted to the wide rim by providing mirrored inclined surfaces such that tire beads of the undersized tire may ride on the mirrored inclined surfaces and are thereby guided outwardly from a center trough of the wide rim to opposing bead seats of the wide rim during inflation of a tube disposed within the undersized tire.
