A big solid urethane wheel with a perfect aspect ratio. The highest level of traction and faster top end make a great downhill and GS wheel. Also great for carving and cruising on larger boards. Extremely smooth, even on rough surfaces. It rolls over everything in its path.
For people who want more drift in their rides without wanting to ride Pink wheels, the Classic Formula urethane in translucent Red 78a and in Amber 81a is the answer.
