The most iconic and classic bearings on the market have been subject to an upgrade. Bones Race REDS have been constructed with the utmost precision in mind. They are made using upgraded top quality bearing steel. Each bearing has a built in 0.200 spacer to provide the perfect 0.400 spacing between bearings meaning there is no need for speed washers and the bearings are better aligned - the axle is also reinforced. With removable rubber shields for easy cleaning, a high speed nylon ball retainer, and built for skateboarding, they come pre lubricated with Speed Cream and are ready to roll. 8 red bearings and a sticker included as always!
