stop making threads about freaking bearings.
+1.
Just go out and buy bearings.
ABEC 5 = Stock, ok
ABEC 7 = Good
ABEC 9 = Strong, fast Very good.
ABEC 11 Probably one of the best "ABEC" bearings.
If you want THE BEST. Get ceramics, if you want a little les performance then ceramic, but more the ABECS, then get Titanium.
Bearings dont really make that much difference to speed, its your wheels that make most difference.
