    摘要: A golf club (40) has a golf club head with a large mass, relatively short club length and a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 5000 grams-centimeters squared. The golf club head (42) preferably has a volume ranging from 400 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared. The golf club (40) preferably has an inertia ratio greater than 0.0019.

    摘要: A golf club (20) having a club head (22) with an interchangeable shaft (40) is disclosed herein. The golf club (20) includes a tube (44, 144) mounted in the club head (22), and a sleeve (46, 146) mounted on a tip end (50) of the shaft (40). The tube (44, 144) includes a tapered portion (60, 160) and a rotation prevention portion (62, 162). The sleeve (46, 146) has a frustoconical portion (72, 172) and a keyed portion (74, 174) that are respectively received in the tapered portion (60, 160) and the rotation prevention portion (62, 162) of the tube (44, 144). The golf club (20) further includes a mechanical fastener (48, 148) for removably securing the shaft (40) to the club head (22).
