yeah, theyre for skateboard and scooters
a skateboard is less eco friendly because it use trees to make a skateboard there for the bike is more eco friendly
FKD bearings
Bones Swiss but they're expensive but they're worth it
yes... unless if they are bearings for the bear trucks with the larger axle... but those are not standard on anything, even higher end longboards use standard bearings.
a skateboard has 8 bearings. 2 bearings inside each wheel facing opposite ways inside each wheel
depending on your bearings
Pretty much. Most skateboards, quads, inlines and scooters use the same industry standard "608" sized bearings.
pop them out of the wheel
no
Probably not considering they're roller blade bearings
Bearings are used to let the wheels spin freely and with minimal drag.
