Query: Good bearings *EDIT*

The bearings are good, but I don't know if they are worth 40 dollars. They are not as good as my bones reds which were 13. Although they are not fully worn in. We'll see once they are.*EDIT*I am very upset with my $50.00 purchase. I have been riding them for awhile now and they are starting to get loud and annoying and not even very fast.
