Pinch Flat Meaning in Cycling

A pinch flat is a specific type of tire puncture caused by hitting a hard object. When a tire hits a sharp edge like a curb, it compresses completely against the metal rim. This action pinches the inner tube in two places, creating two small holes. Cyclists often call these snake bites because the holes look like tiny fang marks. These flats usually happen when your tire pressure is too low for the terrain. Keeping your tires pumped to the correct pressure prevents the tube from touching the rim. For example, a mountain biker might get a pinch flat after landing a jump on a sharp rock. Carrying a spare tube is the only way to fix this issue during a ride. Most modern tubeless tires eliminate this problem by removing the inner tube entirely. It is a common frustration for new riders learning to hop over obstacles.
