I may have one, don't think I ever used it. What is bolt pattern and center hole? Don't think all are same.
Fits BST, Marchesini, OZ and Rotobox Wheels * These sprockets meet and/or exceed O.E.M specs and offer a perfect fit * Sprockets are black in color and Hard-anodized for strength. * Sprocket Dimensions - 76mm Hub Diameter x 100mm Bolt Circle x 5 (10.5mm Bolt Holes)
Only got 48 with that bolt pattern. It is actually from PVM wheel which uses same bolt patter but 80mm hub.
