Sold as Pair with Large Flat Washers & a Sticker .975" Dia x .60" High (24.77mm Dia x 15.24mm High) APS rides a couple of points softer than they test, so order accordingly Hard durometer bushings (95.5a - 93a) are for heavier-weight riders (over 125lbs) and allow for a nice tight set-up. Medium durometer bushings (88a - 78a) are for medium-weight riders (75 - 125lbs) & those looking for a looser setup in the RoadSide position when coupled with a harder duro bushing. Soft durometer bushings (73a - 68a) are for light-weight riders & those looking for aloose setup in the RoadSide position. Excellent when used as a Barrel/Chubby combo - but incredibly fun and variable when used in the Roadside position in combo with other shapes & or duro's in the Boardside position.
