When you spend most of your time in mid-air, you need maximum control and freedom of movement. For tricks and dirt riding, most bikers prefer to rely on large, robust platform pedals, which often have additional pins for a firm grip on grippy shoe soles. Body tension and technique usually win out over SPD systems here as riders must be able to get their feet off, and more importantly, back on the pedals, in the blink of an eye. The most important features are a flat construction, high-quality bearings and the possibility of adjusting the grip to your own preferences by the number and length of replaceable pins.
