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.
