The patented design "SpinTrue" wheel weights by Kibblewhite Precision Machining are made from high grade stainless steel with a chrome finish. Their design clamps to the nipple, rather than to the spoke and can be reused time after time. Weights split evenly and are held together with two stainless steel screws for a secure fit every time. Available in various weights and in two sizes to fit small spoke nipples, measuring .250" to .300" (6.35 to 7.62mm) perpendicular to flats, or large nipples, measuring .300" to .350" (7.62 to 8.89mm) perpendicular to flats. Small size weights fit the spoke nipples used on most Harley models.
