Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.
X Formula (XF) - XF X-Formulas roll over rough terrain like softer wheels do, but slide much like a harder wheel will.
V6 Shape - Wider contact patch with side-cut walls for less drag, giving you longer grinds and greater stability.
79b (99a) - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.
The 'b' scale measurement reads 20 points lower than the 'a' scale: 79b would equal a theoretical hardness rating of 99a.
