SHARK WHEEL
The ability to go over rough terrain is the #1 advantage. The 30 degree approach angle of the Shark Wheel strikes obstacles at an angle and tends to push them left and right out of the way. A traditional wheel acts like a steamroller and tries to go over objects, while Shark Wheels tend to move around them. The angle also reduces shock significantly (think of going over a speed bump in a car an angle to reduce the shock)
