True Temper XP115 Golf Shaft Review

True Temper XP 115 Iron Shaft


By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter

A heavier model of the True Temper XP iron shafts was released in 2014. It joins the 95 and 105 gram versions reviewed earlier. I have been told an 85 gram version has been released in Asia and will likely become available in the US in 2015.

I have added new charts and expanded the measurements I am taking on shafts. The new Fit2Score instrument includes an appliance for measuring hoop strength. This is explained in an article in the technology section. The EI bend profiles show the shaft bend profile as a series of measurements of 10 inch sections of the shaft, in 1 inch increments. While this shows us a detailed view of the shaft and allows for comparison with other shafts it does not show how the shaft behaves when loaded. The deflection chart shown below uses the EI measurements with a load applied to the tip and butt of the shaft, illustrating how the shaft bends when loaded. This is a classical method for measuring shafts. It was done on a deflection board. With EI measurements we can do it with math and chart the results.

Enjoy and Good Golf,

The True Temper XP line of shafts solves a problem I have had with True Temper iron shafts. There simply were too many models for me to understand. Now, with a 95, 105 and 115 version of the same design we have a uniform set of weight and stiffness fitting options in the weight range that fits most golfers. If we look at a subset of this, the 95R, 105R, 105S, 115R and 115S we have a fitting matrix with nearly identical bend profiles. And that is a great mix of mid weight fitting options for a product that is available in many fitting carts.

    Great information. I tried the XP105 and loved it. The feel was similar to DG (am I crazy for thinking that?) but easier to swing. Shame these’s aren’t available in parallel tip for us hobbyists. 1 question/request though: could you guys please analyze TT Lite XL? I know it’s not as glamorous as DG or PX, but it’s supposedly very popular with professional clubfitters. Having built a set myself, it seems like an underrated shaft.

    • Perhaps some day there will be enough time to do some of the historical products. At the moment I can hardly keep up with the new stuff.

    Hi Russ! Hope you’re good. Did you find any major discrepancies between The XP 115 and the Modus 3 125 (S/X flex). The EI bend profile looks similar for a single iron, but not so sure for the whole set. The fact is there’s not so many places around where we can try the Modus shafts. Many thanks for sharing your knowledge.

    • The Modus 125’s are much stiffer and heavier than the XP 115’s. The butt stiffness is much different. The XP’s go softer toward the butt, the Modus 125 progress uniformly to the butt. I have not seen any discrepancies in the set profiles of either the Modus3’s or the XP’s. Both are great, consistent products.

    Can you build a set of ascending weight shafts out of a series of the different weights. I was thinking 115R in the 50, 55, 60 W, the 105R in the PW, 9, 8, and the 95R in the 7, 6, and 5.

    • Sabergo,
      That is an interesting idea that would take some study. It is not exactly easy to determine what will work. I have done something like what you described, but I did so with the assistance of an extensive knowledge base of shaft profiles and my measuring instrument. The issue when mixing weights and flexes is to keep the stiffness gradient consistent. I did this by hard stepping the lighter shafts in the long irons and soft stepping the heavier shafts in the short irons.
      Without being able to look at inch by inch profiles off all the shafts in the sets you want to mix, you are likely to end up with a mess.
      I just looked at the ascending weight dynamic golds. I am not certain when the product line goes public. I believe soon. It would be wise to wait for these to come to market. I have only looked at the X100’s, and the set I saw may be a tour weight version. It really looked good and is the best and most consistent set of ascending weight shafts I have ever seen. BTW, they are flighted.

    • I recently reviewed the Dynamic Gold AMT’s. They are the ascending weight design we have been waiting for. Use them rather that trying to concoct a set.

    Hello there, thanks for the great analysis… I was wondering if you could post the FM frequencies for the XP range shafts; I know my KBS tour Stiff is around 6.1but I guess the XP range has much lower frequencies and probably a good match to my current shaft could be the XP 115 in the X100 flex….
    I am not really sure I express myself in the right terms but I hope you understand what I am talking about… thanks a lot for all the great reviews.

    • Sorry I no longer do anything with frequency other than check for radial consistency. Long ago I wrote frequency charts allowing for user selection of the frequency scheme, Brunswick or PCS, or select their own slope and intersect. As I learned about EI the entire notion of frequency rating lost validity. It is ok to rate shafts of known bend profiles but has little value in comparing shafts with dissimilar material, weight or profiles. I do understand what you are talking about in more detail than you could imagine.
      Several years ago I was introduced to the idea of using area under the EI curve as a shorthand system for cross referencing shaft stiffness. The idea was the brain child of Jeff Meyer, now with Loomis, formerly loomis, Aldila and Acushnet. Unlike frequency it was validated by his testing for player feel. It is not affected by material resonance or by shaft weight. The weight of a shaft itself becomes part of the frequency. That makes comparisons valid only for uniform weights. Then there is calibration of the instrument and the actual tip weight and style used. None of which were ever standardized.
      That is the long answer.
      The short answer, sorry, I don’t know how the measure frequency uniformly.
