Abstract: A pivot joint for a bicycle frame is described, which includes an inner bearing sleeve concentrically disposed within an outer bearing sleeve. The inner bearing sleeve has an outer bearing surface in rotatably sliding contact with an inner bearing surface of the outer bearing sleeve, such that the inner and outer bearing sleeves are rotatable relative to each other about a central pivot axis to permit relative rotation of the frame components joined by the pivot joint. Each of the inner and outer bearing surfaces includes a substantially axially extending region and at least one angled bearing region that defines an angled raceway surface thereon. The angled raceway surfaces are disposed at an angle relative to the central pivot axis and meet in bearing engagement with each other to define a slip plane disposed at the same angle.
