Covington, Ga. — Adding to its already popular TOUR level golf clubs and balls, today Bridgestone introduced its new Gravity Chamber (GC) series of irons for longer distance, higher moment of inertia and improved launch conditions. The GC Series features two models, the GC.MID and the GC.OS, designed to make shots easier to control for two distinctly different types of players. The GC series employs a technology that allows Bridgestone engineers to remove inefficient weight from the clubhead where it is not helping to improve golfers’ games, and strategically repositions it to create a center of gravity at an optimal location, improving launch conditions and accuracy.


The GC.MID irons provide the feel better players demand, with forgiveness golfers of all ability levels can use. The GC.MID features a Gravity Chamber in the back cavity of the clubhead from which significant weight is removed. The weight is repositioned by using Gravity Disks that increase moment of inertia and as a result produces a reduction in clubhead twisting on off-center hits, generating a straighter ball flight.

The strategic placement of the disks creates a precise and progressive center-of-gravity location that provides enhanced control and improved launch conditions. The combination of repositioned weight and progressive center-of-gravity produces long irons that fly high and are easy to square, and short irons that have a flatter ball flight with greater stability for ultimate shot shaping potential. This is accomplished by positioning the disks farther apart in the long irons and progressing the disks closer together throughout the mid and short irons.


The GC.OS irons provide extreme forgiveness for players seeking ultimate relief on mis-hits and high-flying iron shots for long distance. The GC.OS set also removes weight from the back cavity in the form of the Gravity Chamber. The saved weight is positioned to the gravity disks in the extreme corners of the back cavity of the clubhead creating a center-of-gravity that maximizes forgiveness and makes all clubs easier to hit high, long and accurate.

Both sets of Gravity Chamber irons are created from 431 soft stainless steel for tremendous feel and consistency. The GC series of clubs all feature a thin-face design that increases ball speed at impact, translating into irons that fly further. In addition, the strategic location of the Gravity Disk placement in both sets produces a more solid feel and sound when striking the ball.

“The GC series of irons are our most forgiving clubs yet,” said Mike Moxie, Golf Club Marketing Manager, Bridgestone Golf. “By providing better players with unsurpassed feel and workability that they demand, yet providing some assistance to those players who aspire to play a premium level product, we feel that we’ve created two sets of irons meeting the requirements of a wide range of skill levels. Don’t be surprised to see people in your weekend foursome and the best players in the world relying on this breakthrough technology this fall.”

The GC.MID irons are available in 2-PW with stock Nippon® NSPRO® 1050GH shafts. The GC.OS irons are available in 3-SW with stock Nippon® NSPRO® 950GH shafts. The clubs also feature a Golf Pride® Gravity Chamber grip. Custom options for grips and shafts are available. (The GC.MID will be the first clubs in the Bridgestone line that will be available in a left-handed model (available Spring 2007).

Both the GC.MID and GC.OS irons will feature a suggested retail price of $699 (steel) and $799 (graphite) and will be available at golf specialty stores and green grass retailers nationwide, beginning September 2006.
