This solution gives a sense of security, precise steering and proper control over the rollersThe use of technologically advanced construction allowed to obtain a small weight of the roller while leaving a large range of movement. Such a shoe construction means that even the smallest movements of the foot are transferred measurably and precisely to the running gear.What is the ABEC standard?ABEC is a set of tolerance standards used in the production of ball bearings. Developed by the American Bearing Manufacturers Association (ABMA). The standard classifies bearings into five classes: 1, 3, 5, 7, 9 (the higher the number, the more precise the workmanship). Individual bearing parameters are achieved by segregating components, from balls, inner and outer rings, to the type of lubrication.Saying that ABEC 9 bearings are better than ABEC 5 would be a great simplification. For example, the ABEC 5 bearing was created with the use in a given type of roller skates (usually recreational skating) in mind, while ABEC 3 bearings are mainly offered in children's roller skates, while ABEC 5 is a proposal for skaters who value durability much more than speed. ABEC 7 is the perfect optimum between durability and relatively high speed. ABEC 9 bearings are almost the highest technological shelf, they are designed for the highest models and are usually chosen by people who value impeccable quality.Size converter:EURO size3737.53838.5394040.5414242.5Insert [cm]23.023.524.024.525.025.52626.527.027.5Additional materials: Manufacturer's WebsiteYouTube Channel Manufacturer's catalog
