Redefining Round

A company called Shark Wheel is reinventing the wheel. Instead of the conventional circular shape, this new skateboard wheel is based around a cube shape. The company claims its new wheels ride smoother, faster, and offer better grip than traditional skateboard wheels.

The wheels are based around a shape that fits inside a cube. They aren't quite a square, and aren't quite circular, but are made up of three strips, each of which create a helical shape when they roll. This forms a sine wave pattern where the wheels make contact with the ground. 

The new wheels should start hitting the streets in September, 2013.
