Brake Inline Skate Brake is an absolutely necessary element for most beginner roller skaters. Thanks to it, even people with no experience can quickly master the skill of braking while driving What is the ABEC standard? ABEC is a set of standards tolerances in the production of ball bearings. They were developed by the American Bearing Manufacturers Association (ABMA). Five tolerance classes have been distinguished: 1, 3, 5, 7 and 9 (from the largest to the smallest tolerance). The higher the number, the more precisely the bearing is made. The individual bearing parameters are achieved first by segregating the balls, inner and outer rings, and finally by using a lubricant. In fact, it is difficult to say that the ABEC 9 bearing is generally better than the one with number 5. The ABEC5 bearing was created for a specific use in a given model of roller skates (usually for recreational skating), and e.g. type 3 bearings are mainly proposed for children's roller skates, while ABEC5 is a proposition for beginner roller skaters who place a high priority on durability. over speed. ABEC7 is the perfect optimum between durability and relatively high speed. ABEC9 bearings constitute almost the highest technological shelf, they are intended for the highest models and are usually chosen by people who value impeccable quality.
