I think the most durable would be bones. but ive skated forms for bout a year of hard skating(3-5 hrs a day) and they've only worn down a little bit.
No way. Its impossible
The skateboard have wheel & axle and screw, the wheel is obvious the wheel and the axle is the truck and i think the screw is the hardware.
the circumference of the wheel
Just get indys. if you break em you get another pair free
bum
Yes because on the bottom of the skateboard the wheel would be the wheel and the cylindrical metal part next to the wheel is the axle.
pop them out of the wheel
the hardness of the wheel. The higher the number, the harder the wheel will be :)
a skateboard has 8 bearings. 2 bearings inside each wheel facing opposite ways inside each wheel
definetly
its cant be perfect but try to buy one with a durable deck, strong trucks and wheels.
Most wheels are simply urethane added to an existing skate wheel. Made out of a durable material.
