Powell & Peralta "Rat Bones" wheelset. 60mm diameter, 44mm width, 90a hardness [green, blue], 85a hardness [black]. In the mid 80s you started seeing Powell & Peralta pros like Tony Hawk and Steve Caballero stepping away from the larger conical style Cubic wheel to make use of the lighter, more agile Rat Bones wheels. It was definitely rarer to see the big, wide conical style wheel again in the mid 80s after wheels like Rat Bones, Skull Skates Craniums and Alva Rocks hit the streets. The classic, mean looking re-issue Rat Bones really compliment mid 80s cutaway and pig old school shapes and also work out great on contemporary cruiser boards. Available in black [85a], green [90a], or blue [90a]. Set of 4. Made in the USA.
