Bones Bearings spacers are an important aspect of any skate or scooter set-up. They help distribute weight and tension between the two bearings in your wheel, which allows them to roll faster, hold together longer, and provide a smoother ride. They are small but very worthy investment in any skateboard, rollerblade or scooter. Bones Bearings themselves are easily our best selling bearings, so it's a name you can trust.
Combine with washers in between your wheel axle nuts for a faster roll.
