Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.
Wheel Profile
Wide - More traction and stability at high speed so you'll be less likely to slip out of your line.
Formula
Dragon Formula (DF) - DF-93A Dragons can roll over rough terrain, grip, and slide like 99A & 101A wheels do. Its higher rebound means you won't lose speed in bowls or parks and will roll much smoother and faster on rough streets and sidewalks.
Durometer
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.
