6 Ball Bones Super Swiss Skateboard Bearings Bones have been making the best stuff for the longest time. Their bearings are the benchmark when it comes to quality, speed and durability. We have stocked them since they began. These Super Swiss 6 balls have downsized the contents of each bearing. One less ball means they are lighter. The main advantage is that one less ball means less friction and that means faster acceleration. These things fly like the wind...• Single, non-contact, removable rubber shield allows for easy cleaning and less friction• High speed nylon ball retainer provides added strength and speed.• Pre-lubricated with Speed Cream™ racing lubricant.• Skate Rated™ clearances, tolerances, materials and lubricant provide the best performance and durability possible.• Best selling high end skate bearing in the U.S.A.• Set of 8 bearings• 4 bearing spacers• Instructions• Sticker More from Bones at Slam City Skates More Skateboard Bearings Bones Super Swiss 6 Ball Skateboard Bearings
