Designed to provide a lively and energetic ride, Orangatang Nipples will revitalize any setup for carving, pumping, dancing, freestyle and freeride. Formula Nipples are poured in the extremely high rebound Randy Urethane formula. Orangatang stumbled on this urethane a few years ago while testing ultra high rebound formulas for wheels, but found this urethane to actually be too high rebound for a wheel urethane. Perfect for a bushing. The bottom bushing carries most of the rider’s weight, so it is compressed more than the top bushing. The top bushing engages mostly when the rider leans in one direction to turn. To account for this difference in loading, the bottom bushing is slightly taller than the top. Both top and bottom barrels are beveled on one edge for a better fit with large cupped washers (such as the stock parts on Paris and Tracker Racetrack trucks). However, we recommend flat washers in general.
The Nipples feature three hardness ratings: soft, medium, and hard.
These are roughly equivalent to ratings of 85a, 87a, and 89a on the Shore A durometer scale. The reason there is chosen to use a relative hardness scale for these bushings is that Nipples feel and respond differently than many equivalently rated bushings, due to their dimensions. The Nipples feature a slightly larger-than-average diameter that is intended to provide more leverage against the hanger and more meaty volume to compress in every turn. Combined with a double barrel configuration, this allows for a predictable initiation and very consistent resistance throughout the hanger’s travel, even in softer durometers.
Recommended weight ranges for lower speed (under 20 mph) riding are below. For faster riding, we recommend going harder.
Nipple bushings fit Paris, Tracker Fastrack, Gullwing Charger II, and old (pre-2010) Bear trucks. They are not compatible with new Bears, Gullwing Chargers, or Indys. Nipples work with Randal trucks, but they do not sit completely contained in the bushing seat. Since the Randal bushing seat is so low, however, it does not interfere with the performance of the bushings. They fit Caliber trucks, but the lean becomes very restricted past a certain point.
