• Micro-finished chrome steel balls.
• Heat-treated chrome steel inner and outer races and non-corrosive chrome carbon retainer created these bearings for people who know that they will probably not look after them 🙂 yes we understand! So these guys are extremely hard wearing and will last a really long time for how rough you will treat them.
They are an absolute favourite for outdoor skating, extra sets or the skate till they die type.
