I'm pretty new to skateboarding and I've ordered my first "real" deck. The shop mailed me which ABEC I want to have for my ball bearings.
The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA).
I've half of a year experience and skating mainly in parks. They let me choose between 3, 5 (their recommendation) and 7.
What to choose?
