Welcome to Gear Concerns You are Fearful to Question, a Golf.com series produced in partnership with Cleveland/Srixon Golf. We investigate some of golf’s most misunderstood golf equipment phrases, names and definitions in this week’s column.

We recognize how puzzling today’s tools terminology can be, and it is about time we do a quick refresher on some of the most obscure and/or misunderstood bits of golfing products terminology. The list under isn’t complete by any means—rather a couple of of the names, definitions and acronyms that we feel are the best to overlook.

Bounce Angle:

The bounce angle on your wedge plays a pivotal part in how it interacts with the sand or turf. Basically put, the bounce angle is the angle formed by the sole and top edge of the wedge when the shaft is vertical. The more bounce angle, the larger the primary edge will rest off the ground, and the a lot more the club will resist digging and “bounce” off the floor. Conversely, very low-bounce wedges dig far more and are commonly deemed less forgiving.

Cast vs Solid:

A forged clubhead is designed by pouring molten metal into a mould, which is then cooled and taken out. A solid club is hammered out a one billet of metal till it’s shaped into the preferred form. Most concur that solid irons generate a softer experience, but cast irons are inclined to have better perimeter weighting abilities for far more forgiveness. There are exceptions to each policies, nevertheless, and occasionally golf equipment are crafted of numerous pieces that are both equally forged and forged. Reward perception: a milled club is one particular that is carved out of a solitary piece of steel.

Gear Issues You’re Worried to Talk to: Should really I adhere with just one kind of golf ball?

C.O.G. stands for centre of gravity (frequently dubbed CoG or just CG) and it correlates to the specific position in the clubhead in which it is in great balance. Where by the CG is placed in the head is critical—forward CGs (towards the facial area) create decreased launches and lower spin with a lot less forgiveness back CGs generate bigger launches with larger spin and a lot more forgiveness. In addition, greater CGs deliver larger spin fees and lessen launches, and decreased CGs develop reduced spin costs and larger launches. Now, go forward and browse that yet again. We have to do that all the time.


C.O.R. (or just COR) stands for coefficient of restitution, which is the ratio of strength transfer when two objects collide. A great transfer would have a 1 ranking, but the utmost allowable COR permitted by the USGA is .830. Most modern-day drivers from the leading OEMs all have .830 COR rankings, which is almost certainly why you do not hear it utilised in advertising components like it was a decade or so in the past. It nonetheless matters while, especially as manufacturers are carrying out all they can to max out the allowable COR in not just drivers and woods, but in irons much too.

Dynamic Loft

Your clubs have a constructed-in static loft, which is commonly printed on your driver, woods, wedges and at times on your irons.  Dynamic loft is different—it’s the loft you produce at impact, influenced by issues like your angle of attack, your forward shaft lean, shaft flex, whether or not the club is open up or shut and the place on the experience the club can make make contact with with the golf ball. Clubfitters who use start monitors fork out cautious awareness to your dynamic loft at affect, generally creating adjustments to your golf equipment to strengthen how successfully you strike the ball. Instructors take take note of it also, generally aiding golfers lessen or improve their dynamic lofts for far better ballstriking.


E.V.A. (or just EVA) stands for ethylene vinyl acetate, which is a blend of two little ones of plastics, and it is the foam generally identified as the cushioning layer in today’s athletic and golf footwear. It is quickly formed and shoe suppliers can make it in different degrees of hardness. Here’s what you will need to know, though. Shoes with cushioning that have increased degrees of vinyl acetate than ethylene are inclined to be extra durable and significantly less brittle as they get more mature.

Equipment Influence

To get how gear outcome operates, you require to know what bulge and roll is. The bulge of a driver is the convex horizontal curvature of the clubface. The roll is the vertical convex curvature of the clubface. Merged, these curvatures affect how the ball spins off the confront when struck absent from the golfing clubs center of gravity. When the ball hits toward the toe, the ball begins to the right with added draw spin. When hit to the heel, the ball starts left and spins with additional fade spin. When hit lower, the spin level off the facial area is larger. When strike high on the facial area, the spin level is decreased.   

Spin Loft

All set to get complex? Below we go. Spin loft is the distinction concerning your angle of attack (the route at which the clubhead is approaching the golf ball) and your dynamic loft at influence. Truth is it’s a but extra complicated than that simply because the swing features in 3 proportions not two, but we’re in this article to keep items very simple. Here’s why it matters—many golfers presume the critical to including spin is to strike down on the ball. And though that’s partly accurate, you also need to improve the angle amongst your assault angle and your dynamic loft at impact, aka your spin loft. That is the key to additional spin.


The sweetspot of any club is not really a spot—it’s a pinpoint on the deal with wherever optimum strength transfer takes place at effect. Gear suppliers often claim their golf equipment have huge sweetspots, but seriously what they signify is they’ve made the space all around the sweetspot a lot more forgiving. And for the make a difference, the sweetpot is not normally in the middle of the experience. Sometimes it is skewed in any course dependent on how the club is created and also exactly where the middle of gravity is located.

Titanium Alloy  

Ever marvel why no two titanium motorists sense the same? Which is in element for the reason that no two titanium alloys are exactly the identical. The titanium applied in drivers is essentially an alloy—which is a mixture of a lot more than one particular variety of metal. Titanium in its uncooked kind is very robust, but mixing in numerous steel compounds can truly make it even more robust and much more adaptable/fewer brittle.  


You have no doubt listened to of tungsten, but you could not know what it is. Tungsten is a steel that is heavier than lead and denser than metal, making it a top alternative for equipment producers to use for boosting the inner weighting of a club. It can be located in each form of club, usually to greatly enhance the heel/toe weighting or to manipulate mass up or down or towards the front or back again.

Urethane vs Ionomer

Golf balls generally have handles created of either a comfortable and resilient urethane polymer or a a lot more strong yet firmer Surlyn ionomer. Urethane-included balls tends to charge extra to manufacture, but also have that softer come to feel and better spin effectiveness that greater gamers are inclined to desire. For instance, all the designs in Srixon’s Z-STAR line have urethane addresses, but Srixon requires it a phase further and provides SpinSkin engineering, which features Slide-Ring Content (SeRM) to enhance friction and optimize spin on chips and pitches. The far more affordable Q-STAR golf balls have an ionomer address for extra durability, but also have SpinSkin tech that digs deep into wedge and iron grooves, maximizing spin for a lot more manage and a lot more stopping power.
