What precisely is torque? Ought to I care?
The primary one is easy. The second, nonetheless, can get a bit convoluted.
The precise language varies however, within the realm of golf shafts, torque is a quantity (measurement) that communicates how a lot a shaft twists below a prescribed quantity of drive. The decrease the torque quantity, the larger the resistance. And vice versa. For instance, a chunk of rebar would have little or no torque whereas braided rope would produce a a lot increased quantity.
TORQUE BASICS
The quantity of torque a shaft has doesn’t matter. Or, extra precisely, torque isn’t universally relevant. Decrease torque isn’t higher. And better torque isn’t unhealthy. It’s not like counting energy.
That apart, the standard pondering that increased swing velocity golfers who produce extra drive all through a swing can profit from shafts with much less torque has benefit. However it’s not completely true.
Simply because the inverse—that slower swing velocity golfers all the time require shafts with larger torque—isn’t fully correct both.
So what’s the right reply? As you doubtless anticipated, it relies upon.
Most every bit of golf gear has measurable traits: loft, lie, face angle, weight, stability level, and many others.
This creates equal components readability and confusion. Loads of traits are topic to uniform measurement methods. For instance, loft is measured in levels. Weight is recorded in grams. And just about everybody abides by the identical system.
However torque is completely different.
COMPLICATIONS
Someplace alongside the road, you may need heard that decrease torque shafts are extra correct. Or that they’re higher at resisting forces through the swing. That sort of business language can lead golfers to conclude that “much less is extra.” That’s: much less torque is preferable to extra torque. And that merely isn’t true.
Finally, the purpose needs to be to correctly match the golfer to their preferrred specs.
Additional complicating issues, producers don’t use the identical protocols for measuring shaft torque. There isn’t a single business commonplace that determines which parts of the shaft needs to be measured and the way a lot drive needs to be utilized. Most corporations measure torque based mostly on the tip part of the shaft. However with out constant norms, customers can’t make any significant comparisons between manufacturers and even shafts inside the identical model. Furthermore, phrases like “low torque” or “mid torque” are, at greatest, a generic information.
In consequence, corporations can therapeutic massage outcomes to suit the narrative they need. For instance, let’s say the purpose is to provide a shaft with 3.5 levels of torque. To attain a predetermined end result, the producer applies the specified quantity of drive to the chosen part of the tip. So torque generally is a contrived metric slightly than an precise measurement of a doubtlessly significant specification. It will be like writing down your 18-hole rating on the primary tee after which taking part in the spherical of golf.
I’m not suggesting each shaft producer is complicit or that each model misrepresents torque values to deceive golfers. However it does occur. And it helps clarify why the common time period may not be definitely worth the weight some golfers assign to it.
APPLICATIONS
Arguably, probably the most attention-grabbing present software of torque within the shaft business is Fujikura’s work around variable torque.
It stands to motive that earlier than you may range one thing, you first should measure it. To perform this, Fujikura makes use of a proprietary machine that determines two units of torque values. The primary is a composite whole torque. Let’s say that quantity seems to be 4.2 levels. The identical machine additionally helps engineers decide how every part of the shaft (butt, mid, tip) contributes to that whole quantity. To make clear, shafts would not have uniform torque. Put otherwise, the torque measurement within the tip part shouldn’t be the identical because the butt or mid-section.
The appliance of this line of pondering is that Fujikura can alter the torque profile of every part of the shaft to perform particular efficiency targets. Speeder NX is the primary Fujikura shaft to characteristic Variable Torque Core know-how. With Speeder NX, Fujikura targeted on stiffening torque within the tip and deal with/butt sections. In participant testing on Enso, Fujikura’s proprietary 3D-motion seize system, Speeder NX helped golfers higher management dynamic loft and face closure charges.
As well as, the lately launched Ventus TR employs an identical, although extra remoted, technique. Particularly, Fujikura utilized a virtually weightless Unfold Tow carbon cloth to extend the torsional stiffness within the deal with part.
Fujikura isn’t claiming that the pondering is revolutionary. Torque and its position in shaft design aren’t something new. That stated, quantifying torque over the size of the shaft utilizing trendy know-how is important. Taking it a step additional, Fujikura is making use of this info to supply golfers with a extra in depth library of shafts to higher deal with the distinctive swing traits of a wider array of gamers.
If we agree that no two golfers swing the identical, it appears affordable {that a} larger number of shaft profiles can solely be an excellent factor. Proper?
