Wheel Profile

Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.


Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.

Wheel Shape

Hard Line - Hardline wheels come in a conical shape with sharp edges and an extra wide riding surface for maximum grip and control on any terrain.


101a - Most common durometer offering a good balance between speed and grip. Meant for skateparks and other smooth surfaces.

OJ From Concentrate Hardline Skateboard Wheels - red/white (101a)
Works great for a slick park. But does not slide well for the duro rating
