The relatively small diameter of 51mm makes the Pig Natural Wheels particularly suitable for technical street skating. Small diameter means less weight, less chance of wheelbites, low center of gravity and thus great for everything that has to do with flips and technical tricks, since even low trucks should not be a problem.
With a durometer of 101A, they are also very hard, which means they can accelerate quickly and you can push super fast speeds on smooth surfaces. If there is still a flat session pending in the evening, sketchy bs 180s can easily be accomplished by powerslide as well. ,)
