I am a Roller derby girl and so I am NOT interested in the type of bearings that are for in-line skate! Please tell me how I can tell if the bearings are good for speed or not!
I use Bones Swiss bearings and they have been very responsive and have made a big difference. If you want to know how fast a bearing is most have abec ratings, nine being the highest. However, as Bones Swiss are of better quality and faster than most bearings, they have omitted the abec rating. I highly reccommend the Bones Swiss bearings and if you want to get better than those, you get the ceramics. They are much more expensive though.
