General pro skateboards have element bearings. But most of the time, the company the skateboard is from will probably have their brand bearing. Most pros have element bearings though.
well there's no such thing as a pro skateboard...but what do you mean by what kind of bearings...brand or abec? if you're talking about abec then most pro street skaters use abec-5 bearings, while vert skaters like a bit more speed. so theyll use abec-7. abec-3,5, and 7 are the most common. the higher the number the faster and longer the bearing will make the wheel spin, but they need cleaned often and dont last as long. as for the brand, they will skate bearings from whichever company gives them sponsorship. most pros do not skate element bearings, they skate whoever they're sponsored by.
