With the name C-Taper Lite, most golfers will assume that the biggest difference between KBS’s newest shafts and the company’s original C-Taper shafts is the weight. But even though the new shafts are between 5 and 15 grams lighter depending on flex, weight was actually a secondary concern in the design of the shafts.

Kim Braly, the man who designs KBS shafts, says there’s no reason golfers should change to lighter iron shafts based on weight alone. While he admits that changing from heavier iron shafts to lighter ones usually gives golfers a few extra yards at first, over time Braly has noticed that golfers tend to go back to hitting their iron shots about the same distance.

“You see it all the time on tour,” Braly said. “Guys go to light-weight iron shafts and hit it a little farther. But then a few months later they go back to hitting it their old distances. Their bodies acclimate to the lighter weight.”

So if the C-Taper Lite shafts don’t give golfers extra distance, what do they do?

The new shafts fill a hole in the company’s lineup, which is between KBS’s low-launching, low-spining C-Taper and KBS Tour shafts and the company’s high-launching, high-spinning KBS Tour 90 shafts. They offer a similar feel and the same efficient energy transfer as the C-Taper shafts, but in a profile that is much easier for slower swing speed players to load properly. That gives them the best chance to hit long, straight shots.

To create the new shafts, Braly had to experiment with different shaft geometries, just like he did when he designed the tour-only shafts that Phil Mickelson is currently using, the KBS Tour V2.

Mickelson didn’t care for the feel of KBS’s original C-Taper shafts — he preferred the softer feel of the KBS Tour. But the KBS Tour shafts spun too much and launched too high for him. So Braly spent almost two years working with Mickelson on the design of the KBS Tour V2, which are actually lighter than KBS Tour shafts, but are lower launching and lower spinning.

Can you tell which shaft is a KBS Tour V1 and which shaft is a KBS Tour V2? A KBS Tour V2 shaft (left), has a larger outside diameter and thinner walls in the tip section, which gives it a more penetrating trajectory. 

It seems impossible that Braly could make a shaft that was both lighter and had a more penetrating trajectory, but it’s actually fairly simple to do. Because changing a shaft’s outside diameter (the fatness of the shaft) has three times more effect on stiffness than changing a shaft’s wall thickness, Braly was able to increase the outside diameter of the V2’s tip section to make it stiffer and get the lower-launching, lower-spinning performance Mickelson wanted.

Notice how the KBS Tour V2 shafts, when paired side-by-side with the KBS Tour V1 shafts, have longer steps (in both pairings, the V1 is on the left and the V2 is on the right). This change, combined with the change in wall thickness and outside diameter, gave Mickelson the launch, spin and feel he was looking for in his iron and wedge shafts. 

For a change that simple, why did it take two years for Mickelson to make a change? According to Braly, getting the right performance from a shaft is often much easier than getting the right feel. That’s why the V2 shafts are five grams lighter than the KBS Tour shafts. To make up for the stiffer tip, Braly was forced to extend the lengths of the steps of the shafts and subtract from the thickness of the walls to give Mickelson a KBS Tour-like feel with the performance that he wanted.

Like the tour-only KBS Tour V2 shafts, the C-Taper Lite shafts were able to be made lighter by decreasing the thickness of the shaft’s walls and tuning the shaft’s diameter to create the mid-spin, mid-launch conditions he was looking for from the shaft.

Just how important does Braly think the C-Taper Lite is to his company’s shaft lineup?

“I’m really into custom fitting and I wanted to have a complete product line,” Braly said. “I want to be able to fit golfers into the best product I possibly can. With this new product, I can’t imagine that there are many golfers out there that we won’t be able to fit.”

The C-Taper Lite shafts have KBS’s brushed satin finish, and are available for order now with shipping starting July 8. The R-Flex C-Taper Lite shafts weigh 105 grams, with the S-Flex weighing 110 grams and the X-flex weighing 115 grams. They’ll cost around $39 per shaft.
