This vintage Powell V-IV Bones Skateboard/Rollerskate Wheels is a must-have for any skating enthusiast. The 57mm/95a size is perfect for cruising around town or hitting up the skate park. The bones design is classic and stylish, making it a great addition to any skateboard or rollerskate. There are NO spacers in between the bearings and there is only 1 dust cover on the bearings (it’s on the outsides) Thanks for looking.
