The JPX850 range of golf clubs from Mizuno come as a part of their 'year of innovation' in which they hail a number of technical breakthroughs, industry firsts that all aim to increase ball speed and distance.

The JPX850 driver fits neatly into this story with a next generation Fast Track sliding weight system that allows golfers to dial in the perfect launch conditions for them.

First seen on tour in April 2014 the piercing blue crown set many tongues wagging and the revamped adjustability options mean that is set to continue.

Mizuno first introduced the Fast Track sliding weight system to their MP-600 driver back in 2007 and the fact that competitors have been introducing them to their clubs in the last 12 months is seen as a validation of the technology.

Where Mizuno have the advantage is the years of learning from the original Fast Track system and those insights have been poured into the JPX850 and its next generation Fast Track technology.

Like other manufacturers, Mizuno's research has clearly indicated that optimising spin rate was the quickest way to increase a players overall driving distance so the adjustability of the JPX850 has been geared to allowing players to simply set the driver up for their game.

Mizuno say that, typically, adjustable weight systems only have one 'neutral' setting with fixed launch characteristics but the new Fast Track allows players to set up for a high spin, mid spin or low spin 'neutral' flight which together with high spin, mid spin and low spin in the fade and draw options means players can easily dial in their perfect launch and spin.

The JPX850 comes with twin 8-gram weights that can be located either on the central sliding rail or the two lateral slots located on the heel or toe of the driver.

Together with Mizuno's Quick Shift shaft release system that offers 8 loft options ranging from 7.5° to 11.5° within the one head you can see why Mizuno are confident that the JPX850 offers the ultimate in adjustability.

The head of the JPX850 is a compact 440cc that incororates a "Rebound Crown" to maximise ball speeds by flexing at impact for explosive distance. Coupled with Mizuno's Hot Metal face technology to transfer clubhead speed to the ball across a large area of the face the JPX850

Chuck Couch, VP of Product Management, is confident that with the JPX850 driver Mizuno have brought the Fast Track to a whole new generation of players.

The genius of the new Fast Track is that it adds the dimension of launch angle and spin rate. Now we’re truly in control of maximizing all aspects of their ball flight off the tee

The JPX850 will be available with limited pre-launch availability from November 2014 before appearing at retail in February 2015.
