How important is CG location on a golf irons?
CG location for irons can vary drastically depending on the intended consumer, which ranges from Tour players to game-improvement golfers. In the most general sense possible, golfers require low CG for long irons in order to launch them high, and progressively higher CGs in their short irons to launch them low with more spin and control.
How does clubhead height affect CG?
The taller the clubhead and/or the more weight that is placed on the upper portions of the head, the higher the position of the CG will be in the head. The more shallow the clubhead and/or the more weight that is placed on the bottom or sole of the head, the lower the position of the center of gravity will be.
What is the center of gravity of a golf club head?
The center of gravity position in the club head is initially controlled by the height, width and depth of the club head. Whereby it is influenced by how much of the head’s weight is placed in different areas of the club head. The center of gravity is a single point inside the club head.
How do you measure a golf iron head?
To get an accurate measurement of club length. Measure the club at the angle that the bottom of the clubhead lies in its playing position on the floor. Measure from the floor to the end of the Grip.

What is the loft of a normal 7 iron?
34 to 35 degrees7-Iron Loft | 28 to 35 Degrees A more standard loft for a 7-iron is 34 to 35 degrees, but you can find game improvement 7-iron lofts pushed as low as 28 degrees or less.
What is CG in golf iron?
CG stands for centre of gravity and in a golf club head it is the point that all of the weight is acting through. If you drew a line through all the different vertical and horizontal balance points of the club then the intersection of all those lines is the centre of gravity.
What golf club is 37 degrees?
An 8-iron has 37-degrees of loft and will carry approx 130-yards. A 9-iron has 41-degrees of loft and will carry 120-yards. A Pitching Wedge has anything between 45 to 50-degrees of loft. Carry will be approx 105 to 110-yards.
How do you measure a loft?
The crucial measurement you need to take is from the highest point, directly under the roof ridge, vertically down to the top of the joists below. This can be done with a tape measure, ideally, a metal one that will remain straight. For a conversion to be practical, the height needs to be at least 2.2 metres.
How fast should you swing a 7 iron?
An average golfer will swing a seven iron about 75 mph. This number can change based on the weight of the club and if it is steel or graphite. The faster you swing a seven iron, the further it will go. If you can swing at about 85 mph, you will see distances closer to 165 yards.
How far should a 34 degree 7 iron go?
7 iron = 34 degrees (130 to 170 yards)
Do lower loft irons go further?
As long as the spin rate is acceptable, the new irons, because of their lower center of gravity, are going to produce more speed off the face (due to the lower loft and lower COG) and more distance. But they will still land on the green as soft as an older set of irons (if not softer).
How do you find the center of gravity of a golf club?
"In a golf clubhead, the CG can be determined by balancing the head on its face, sole, or any place on the head; the intersection inside of the head of all these different balance points is the center of gravity of the clubhead.
Where is the CG for a golf club?
Essentially, CG is the point at which an object (in this case a golf club head) is perfectly balanced. The CG of a golf club head is typically very close to the center of the head, as you'd expect, but the exact CG location is extremely important. Any minute changes in CG can have a drastic effect on performance.
Where is the center of gravity on a golf iron?
While CG is mostly found near the middle of an object, it is generally found closer to the face of a golf club due to the face being the thickest and heaviest part of the club. The hosel is also a heavy part of the golf club and this too is located closer to the face.
Where is the CG on a golf club?
The CG of a golf club head is typically very close to the center of the head, as you’d expect, but the exact CG location is extremely important. Any minute changes in CG can have a drastic effect on performance.
What does CG stand for in golf clubs?
When it comes to golf club technology, the term “center of gravity” — “CG” or “CoG” for short — gets thrown around quite a bit, but it isn’t often explained to the average golf consumer.
What degrees are lower lofted wedges?
That’s because lower-lofted wedges (46-54 degrees) are played more often on full shots where higher launch is beneficial, and higher-lofted wedges (56-60 degrees) are used on shots where lower launch and higher spin is important for control. CG is also closely related to MOI (moment of inertia), which we’ll cover in-depth on the next installment ...
What is CG forward?
Here are some basic rules of CG as they relate to golf clubs and performance at impact: CG Forward (toward the face) will lower launch and spin, and generally make the club play a bit less forgiving. CG Back (away from the face) will increase launch and spin, and generally make the club play more forgiving. CG High (toward the top of the club head) ...
Why is CG important?
While CG may seem like marketing speak based on how frequently golf club companies mention the term, CG is actually incredibly important when it comes to performance and feel. Where CG is located on a golf club influences launch, spin, feel, sound, forgiveness, how a shaft performs in conjunction with the club head, and so much more.
Is a low forward CG better for golf?
When it comes to drivers, a low CG design has proven effective for almost all golfers, and most modern driver companies in 2020 have very low CG designs. The challenge for golfers is to determine whether a low-forward CG design or a low-rearward design is better for their game.
Do irons have CG?
Game-improvement irons typically have lower and more rearward CGs throughout an iron set, while players irons have higher and more forward CG locations for greater workability. CG location also influences performance on wedges and putters, too.
What is the position of the CG in the head?
The taller the clubhead and/or the more weight that is placed on the upper portions of the head, the higher the position of the CG will be in the head. The more shallow the clubhead and/or the more weight that is placed on the bottom or sole of the head, the lower the position of the center of gravity will be.
What is the center of gravity of a clubhead?
Finally, the center of gravity is also defined by how far back from the clubface it is located .".
What is CG position in golf?
With this CG position, a golfer is able to hit the ball higher with more backspin, meaning it'll be more controlled and more likely to stay in play. However, some better golfers want a more forward center of gravity while keeping it low, so as to keep that point near where impact happens and lowering spin. That creates some more distance and ...
What is the center of gravity on a short iron?
On short irons, the center of gravity would be a little higher to correspond with where the ball will be struck. With wedges, the center of gravity will tend to move these days in a progressive fashion.
Why do golfers need a low center of gravity?
On irons, most golfers again want a low and back center of gravity to help them get the ball in the air and flying farther. However, better players may want a set of irons with a progressive center of gravity, getting lower as the numbers get lower.
Why is the center of gravity important in golf clubs?
It's a really important feature of a golf club, as the center of gravity -- often just called CG -- helps determine how easy it is to create ideal launch conditions for a golf shot.
How is the center of gravity determined?
The center of gravity is entirely determined by the mass properties of a club. In other words, where the weight is concentrated in a golf club determines the center of gravity position. The more weight placed low and back in a club, the lower and further back the center of gravity will be.
Can you change the center of gravity on a wedge?
It's possible with some fairway woods and hybrids. Generally speaking, you can't move the center of gravity on irons and wedges.
How does CG affect golf?
On a comparative basis: 1 Drivers with forward CG locations often feel heavier than those with rear CG placements 2 A forward CG location will cause the shaft to feel stiffer. 3 Because of the effect on closure rate, forward CG drivers may be harder to square, and some golfers will find it difficult to control the club during swing
Where is the center of gravity on a golf club?
As you might expect given its label, the center of gravity is always located very near the center of the clubhead. The CG of every driver measured for this series of articles is located within a box that’s 14mm front to back and 12mm top to bottom.
Why does the driver head have a slight forward bias?
Now that said, the CG location of a driver head has a slight forward bias because: The face is much thicker and heavier than the rest of the body. The hosel (and all of its weight) is near the front of the club. 2.
What are the three things that affect CG movement?
The significance and impact of flipping, sliding, or any other type of CG movement depends on three things: 1. The direction the weight is being moved. 2. How much weight is being moved. 3. How far the weight is being moved. The more weight you can move over a greater distance, the more the CG will shift.
Why does CG location matter?
CG location matters because it heavily influences both performance and feel. How high your driver launches, how low it spins, how it feels, and how it sounds at impact, that all begins with its center of gravity. Before we dig deeper into the specifics of how CG location impacts both performance and feel, there are a few things we need ...
Why are forward CG drivers harder to square?
A forward CG location will cause the shaft to feel stiffer. Because of the effect on closure rate , forward CG drivers may be harder to square, and some golfers will find it difficult to control the club during swing. While it may not be universally true, I ...
What is the center of gravity?
Center of Gravity (CG or CoG) is the point at which all of the weight of an object appears to be concentrated. An object can be balanced on a small flat point placed directly beneath its center of gravity.
The Wedge Guy: Understanding CG
One of the most misunderstood concepts involved in golf club design is that of “CG,” or “center of gravity,” also “center of mass.” While this particular measurement of any golf club head can certainly offer insight into its probable performance, it is not the “be all, end all” with regard to any club’s specific launch or forgiveness attributes.
2022 Waste Management Phoenix Open: Best prop bets
The PGA Tour heads to TPC Scottsdale this week, with a raucous crowd ready to greet a whole host of huge names that are looking to get their hands on the trophy in the desert.
What percentage of golf clubs are iron heads?
Design of Golf Iron Heads. Recent innovations give golfers many options when it comes to their irons. The irons comprise approximately 65 percent of the golf clubs in a standard set. The evolution in their design has advanced as rapidly as any other facet of the game, because of changes in agronomy and the use of physics and computer-aided design.
Where is the cavity back on an iron?
Cavity-back irons derived their name from the fact that some of the weight from the back of the iron was moved to the perimeter of the club head, leaving a cavity at the back of the iron.
What is a hybrid golf club?
Hybrids are a cross between a wood and an iron that have become extremely popular because they are easier to hit than the long irons. The front of the club looks like a long iron, while the back of the club resembles a wood, but not as bulbous in appearance.
