These Pivot Cups are sold as 2 Pair (4 Pieces) Compatible Only With PowerDyne Thrust Plates. Set of 4 to outfit a complete set of skates. Riptide's Premium WFB Pivot Cups are a perfect upgrade to your trucks. RipTide's Pivots are specifically designed for each truck. Our Pivots offer a Lively & Responsive feel. Hand-poured into Custom-made molds. The cup end is machined to fit into base plate accurately. There are no machining imperfections and no heat-affected zone in the super smooth pivot contact area. All RipTide's WFB Pivots come in our exclusive Internally Lubricated WFB Urethane in 96a durometer. RipTide's Pivot Cups & Tubes are the result of years of testing and fit checking. We do not offer universal pivot styles because of the compromises a universal pivot force you to make. In some cases, we offer both tubes & cups for the same truck. Both will offer the smooth turning benefits of Riptide's exclusive internally lubricated WFB Urethane in 96a. Tube Pivots offer even lower friction due to the reduced surface contact with the nose of the hanger.
