摘要： A golf club shaft includes a first strain gauge attached to a first side of the shaft facing the striking direction, a second strain gauge attached to a second side of the shaft facing the address direction at right-angles to the striking direction, and a third strain gauge which is capable of measuring the twist of the shaft. Detection signals from the strain gauges are used to classify a shaft into four types according to the swing type of a golfer in accordance with at least torque or kick point.
