The Titleist 975D driver was produced from 1998 to 2001. This driver was aimed at mid- to low-handicap (intermediate to advanced) golfers, much like many clubs in the Titleist line. The 975D was used by Tiger Woods during his 2001 PGA Tour season.
Shafts
The Titleist 975D came with five different graphite shaft choices: the Titleist Select, True Temper EI-70, Grafalloy ProLite, Titleist Ultralite 65 and the Titleist Ultralite 50. The Titleist Select, True Temper EI-70 and Grafalloy ProLite came in regular, stiff and extra-stiff flexes. The Titleist Ultralite 65 and Titleist Ultralite 50 shafts came in regular, stiff and extra-stiff flexes, and also offered more flexible options. The more flexible shafts were lighter than the stiffer options: the Titleist Ultralite 50 Graphite weighed only 1.76 oz., while the extra-stiff Titleist Select Graphite weighed 3.17 oz.
Loft
This driver came with eight different loft options. This refers to the loft of the club's face, which determines the flight and angle of the ball when it is struck. The lofts for the 975D started at 5.5 degrees and moved up one degree at a time (6.5, 7.5 and on) to 12.5 degrees. Lower-lofted faces are best for players who struggle to keep the ball on a lower trajectory, while golfers using 12.5-degree drivers normally have trouble hitting the ball high.
Volume
This driver's clubhead volume was 260 cubic centimeters (cc), which geared it towards better players. The maximum allowed volume for drivers, according to the United States Golf Association, is 460 cc. Larger cubic-capacity heads are less likely to twist on impact and will usually have a bigger sweet spot, making bigger drivers more forgiving and easier to use for beginners.
