i have bones reds bearings and i dont know if there abec 5 or abec 7 tell me what you think?
bones makes many types of bearings. Some are ABEC rated and the better ones are not. The ABEC rating is for vibration in high speed machines that run at speeds similar to skating over 200 mph. They are not the best design for skating but companies make a lot of them for other reasons and it is cheaper to get them than a design that is custom made. Bones, Twin Cam, Zero Drag, and some other companies have custom designs for their better bearings.
