How ABEC Ratings Work

ABEC ratings are only odd numbers?and start with ABEC 1.

• ABEC 1 is the most crude, the least precise, the most durable, and the cheapest.
• ABEC 3 is what most?cheap complete skateboards?come with, especially skateboards from China. ABEC 3 bearings work?for most skateboarding, but won't roll very smoothly or fast.
• ABEC 5 bearings are the norm in skateboarding. You get a reasonable amount of speed, and at a reasonable cost.?
• ABEC 7 bearings would be very fast and smooth, but very expensive. Plus, you start to run the risk of needlessly damaging them if you skate hard or aggressively. Note that some inexpensive foreign-made ABEC 7 bearings may?not deserve this rating.?
• ABEC 9 and higher bearings would be ridiculous to use in a skateboard unless you are doing downhill luge-style skating or something else where your goal is to go insanely fast. If you aren't spending a fortune on these bearings, then don't trust that they are, in fact, ABEC 9.
