The KBS prototype shaft Phil Mickelson has been using in his 5-PW is finally coming to retail. In development and testing since 2012, KBS's new Tour-V shaft — it was called "Tour V2" before receiving an official name — is similar to the company's popular Tour shaft in feel and trajectory (low-mid trajectory and spin).
Where the two shafts differ is in the weight department. The current Tour shaft ranges in weights from 110g to 130g; the new Tour-V shaft will be available in three different weights — R-100g, S-110g, and X-120g.
“We are very excited to introduce the Tour-V shaft," said Kim Braly, KBS's director of R&D and tour operations. "It has been tested and perfected over the past year and a half, and truly delivers on offering a tight dispersion shaft in a light weight package. The results we get from PGA TOUR player testing are spot on. Dispersion with the Tour-V is some of the tightest we have ever seen and it maintains our signature smooth feel at impact. Lighter weight has become more popular and this allows golfers to swing a little easier."
Aside from the lighter weight, KBS also made the outside diameter (OD) larger — which in turn made the tip section stiffer — and increased the wall thickness of the shaft. The subtle increases to the OD and wall thickness gives the Tour-V a piercing ball flight, lower spin rate and tighter dispersion.
Mickelson, who started using a Tour-only 125g version in 2012 at the Shell Houston Open and won three times this season, including the Open Championship, is the biggest name currently playing the shaft.
Scott Piercy, Padraig Harrington and Paul Lawrie are also using the 125g version of the Tour-V
KBS's Tour-V will be available Nov. 1 in three weights (R-100g, S-110g, and X-120g). It will also be the stock shaft in Callaway's new Apex Pro iron.
