Yesterday we brought you the news of the new Callaway Razr Fit driver, the company's first foray into the world of adjustable clubs.
Now we have an exclusive interview with the man behind the design of the new club, Dr Alan Hocknell, Callaway's senior VP of research and design.
Today's Golfer equipment editor David Connor joined Callaway at Valderrama in Spain earlier this year to get the lowdown on the new range for 2012 and spoke to Dr Hocknell about the technology behind the new club.
He insists Callaway refused to release an adjustable driver until they could be sure it performed just as well, if not better, than their previous offerings and now, thanks to a number of technologies in the clubhead, they say they have done just that.
Watch the video below for an exclusive interview with Dr Hocknell.
