Flatface Dual Bearing Wheels are the fastest, smoothest, most durable wheels we have to offer. This is because instead of a single bearing, it features 2 bearings with a design almost identical to the way an actual skateboard wheel works. Because of the backless design, the only thing contacting the truck is the bearing itself, so they'll roll a lot better than any single bearing wheels possible. You'll have to try them yourself to see what kind of perfection is possible here at FlatFace.
