Bareback bronc riding is a rodeo event where a rider attempts to stay on a bucking horse without a saddle. The rider grips a specialized handle called a rigging, which is attached to the horse's back. The goal is to maintain balance and control while the horse performs various movements to throw the rider off. Judges score the performance based on the rider's technique and the horse's bucking ability. Points are awarded for both the rider's skill and the horse's performance, making it a challenging and exciting event in rodeo competitions.
