Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.
Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.
X Formula (XF) - XF-97A X-Formulas roll over rough terrain like softer wheels do, but slide much like a harder wheel will.
STF V6 Shape - Wider contact patch with side-cut walls for less drag, giving you longer grinds and greater stability.
97a - Offers more grip than harder wheels and more slide than softer wheels. Great for beginners wanting more control on smooth surfaces or for filmers looking for a smooth roll.
Made in the USA - Poured in Santa Barbara, California.
