The RAZR Fit Xtreme's "Speed Frame Technology" focuses on distribution of stress across the clubface, optimizing stiffness characteristics to build a more efficient transfer of energy from clubface to golf ball. The result, Callaway says, is faster ball speed, lower spin and more distance; Callaway Tour golfer Luke List, the company says, gained more than 16 yards total distance relative to the original RAZR Fit. List swings a lot faster, and makes better contact, than you and I do, so don't carried away by that number. The benefits ramp up as clubhead speed increases; still, it's an example of what Callaway states are the distance benefits of the technology.
The Speed Frame Technology also allows for a lower center of gravity - the company claims the CG position is lower than in any other adjustable driver head - and higher MOI. That lower CG is also aided by the Forged Composite crown.
Included in the RAZR Fit Xtreme driver is Callaway's adjustable technology, OptiFit. The OptiFit hosel lets the golfer adjust face angle to open, square or closed positions. One-gram and 13-gram OptiFit weights let the golfer increase or decrease draw bias, with draw and neutral settings. A wider range of available lofts means that there is a wider array of settings for affecting shot-shape and trajectory (and lower lofts have less draw bias than higher lofts).
The Callaway RAZR Fit Xtreme driver will hit retail outlets on January 18, 2013 with a retail price of $399.99. The primary shaft will be the Aldila Trinity, but Matrix 7M3 Black Tie - a heavier and lower-launching, lower-spin shaft - will also be offered.
Callaway's udesign personalization service will have additional options for the RAZR Fit Xtreme, including customized colors for the crown and sole. callawaygolf.com
