I have a velocity, so what size bearing should i buy? Thanks! 
Size A (small)
a size (also called small or duncan sized)
ok thanks! ;D
Why are you buying a bearing for it?
just so i can have a spare
Eh, I wouldn’t worry about it. Don’t get me wrong; spares are good to have, but they aren’t necessary so I would just go without it for now, at least until you would be getting something else.
oh well
Hey. He’s not telling you not to buy a spare.
He just says they aren’t totally necessary.
