发明名称 Sports shaft
摘要 The present invention relates to an improved sports shaft. The improved shaft is comprised of a synthetic material designed to minimize weight and provide a desirable amount of flex. The shaft may include a unique tapered grip portion that dramatically improves the shaft's flex and feel characteristics. The tapered grip portion is tapered lengthwise and widthwise to create a narrower portion that accommodates a player's hand position. The outer surface of the shaft is coated with a gripable material to improve the overall grip and feel characteristics of the shaft. The gripable material comprises a low coefficient of thermal surface conductivity. In addition, the outer coating creates an aesthetically pleasing appearance in comparison with an uncoated aluminum shaft.
