BIG BALLS are engineered to roll faster and last longer by using 6, 17% larger balls, like our legendary Bones Super Swiss 6 bearings. These larger balls let you roll faster, and keep rolling right through dirt that slows smaller balls down. This makes BIG BALLS a great choice for skaters looking for more speed and longer life in their bearings. Skaters have made the Bones REDS family of bearings their #1 choice because of the consistent quality, speed, durability, and value.
