Bones REDS were developed to be an affordable alternative to Bones Swiss. This combination of Skate Rated design, quality components and careful quality control makes them faster, smoother and longer lasting than any other skateboard bearing in their price range, so let the good times roll with Bones REDS.Features:-Includes set of 8 bearings, pre-lubed with Speed Cream, instructions and a sticker-Easy cleaning and relubricating-Removable high speed nylon ball cage-Non-contact, removable rubber shield-Bones Skate Rated Design and QualityNote: All Bones Bearings are Skate Rated to withstand the destructive forces created by high performance skating. This is Powell's way of saying that just using a bearing with an ABEC rating is not enough to ensure that a bearing will perform well for skating, since ABEC ratings were intended for electric motor bearings, not skate bearings. Powell has adjusted the tolerances, clearances, lubricant, and component materials to optimize Bones Bearings for use in dirty, high impact environments where you skate. That's why they roll faster and last longer than mere ABEC rated bearings.

• Single, non-contact, removable rubber shield for easy cleaning and less friction
• High speed Nylon ball retainer for greater strength and speed
• Pre-lubricated with Speed Cream racing lubricant
• Skate Rated clearances, tolerances, materials and lubricant provide the best performance and durability possible

You may notice that some skateboard bearings have an ABEC rating that refers to the bearings precision. The rating was developed not for skateboards, but for machines, so many manufacturers don't even bother with the ABEC rating. The ABEC numbers range from 1-9 using odd numbers only. An ideal rating for skateboards is between 3 and 5
