Longboarding is typically defined as a variation of skateboarding that involves a larger than usual board and softer urethane wheels. Longboards vary in shape and size. Compared to skateboards, longboards are more stable at speed and have more traction, due to larger wheel size and lower wheel durometers. A standard skateboard is typically between 28-34 inches long, whereas a longboard may exceed upwards of 50 inches long. Modern downhill race boards however are typically between 30-35 inches in length, making them more comparable to the length of a traditional skateboard. Many longboards use trucks that have different geometric parameters than skateboards. The skateboards use 'traditional kingpin trucks' while longboards often use 'reverse kingpin trucks.' This hardware change is the key element in the increased stability that longboards offer. The term 'longboarding' encapsulates multiple disciplines of riding. These include downhill, freeride, freestyle, dance and long-distance-push. (Source: Wikipedia.org, CC BY-SA)
