Drop bars are a type of bicycle handlebar characterized by their downward-curving shape. This design allows cyclists to adopt a more aerodynamic position, which can enhance speed and efficiency during rides. They are commonly found on road bikes and racing bicycles. The lower part of the drop bar provides multiple hand positions, helping to reduce fatigue on long rides. Riders can switch between the tops, hoods, and drops of the bar, allowing for better control and comfort. This versatility makes drop bars popular among both competitive cyclists and recreational riders.
