78a - Soft and gooey, this is the most common durometer we see in the longboard/cruiser wheel world. These wheels have great grip for cornering and easily rolls over cracks, small rocks, and rough surfaces without tripping you up. When sliding, 78a wheels have a tendency to smear across the surface of the road, offer great control, slow you down rapidly, wear quickly, and leave thane lines. Ideal for cruising, carving, freeride, and downhill.
Urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
You may notice a discrepancy between what we designate a wide, standard or narrow and what the brands do. This classification is our opinion based on years of skating, as well as looking at the profile of the wheel as it compares to what we believe is a standard profile. You just have to trust us on this.
Wide - Wide wheels provide more traction and stability at high speed, so you'll be less likely to slip out of your line.
Smooth - Smooth wheels have a shiny coating on their surface that is commonly referred to as its skin or mold release. Smooth wheels are generally preferred for their grip and traction.
All-Terrain Formula (ATF) - All-Terrain Formula wheels are poured in a special soft urethane Bones calls "All-Terrain Formula." ATF wheels are excellent for rougher terrain so regardless of road quality, this revolutionary formula will roll you there quickly and smoothly.
This is the riser size we suggest using if you want to avoid wheel bite, essentially the larger the diameter of the wheel the more likely you are to get wheel bite if you don't add risers of this size to your complete, so the larger the wheels the larger the riser required.
