Well i recently bought a pro scooter and bout ABEC 11 bearings. I want to know if the higher number is better or the lower number?
ABEC numbers are nonsense for skates, boards, or scooters. It is a number for vibration in high speed industrial equipment at speeds that would be past 200mph on a board. It can actually be detrimental since the smaller tolerances that are required for the higher numbers by the spec can mean more friction. Bearing friction is way less than the drag caused by rolling wheels. The top of the line bearings actually do not have an ABEC rating since the companies are designing them specificaly for human powered motion and have opened up some of the specs to reduce friction while keeping other parts tight.
The higher bearing number is better for those bearings
