KBS Tour steel iron shaft
Steel iron shafts have dominated the golf marketplace for 75 years. The reason: Consistency and stability. The process for manufacturing steel shafts is easily repeatable, and the performance from one shaft to another is highly predictable.
Who are the obvious candidates to use steel iron shafts? Everybody, says Kim Braly, creator of the KBS steel shaft.
“KBS is sold in 5-gram increments, from 90 grams all the way up to 130 grams,” Braly said. “We can fit any golfer.”
Steel shafts from True Temper and Nippon are available down to the 75-gram range, although individual golfers must decide how light is too light. On the PGA Tour, where swing speeds are among the fastest in the world, more than 95 percent of players use steel iron shafts. Traditionally, skilled players have favored heavier weights – in the 120- to 130-gram range – but interest in lighter weight steel is increasing on Tour and among amateur golfers
The original KBS Tour shaft (well-known because of use by Ernie Els, Steve Stricker, Adam Scott and others) was followed by the KBS Tour C-Taper and the KBS Tour V2, played by Phil Mickelson in winning the Waste Management Phoenix Open. The V2, tour-only at first, was to be sold to consumers later in the year. The C-Taper offers a lower trajectory than the KBS Tour, and V2 has a slightly more penetrating flight than the C-Taper.
