Club Face Angle / Loft Angle

So, Here is a picture of an iron. If you put down the club "correctly" when the buttom/sole of the club to the ground. You should able to see the club from the side like the picture above.

Every club has its own design angle(Loft and Lie) plus the Bounce(I will mention later). The loft of the club will affect to the trajectory of the ball will flight. The higher(More open) the loft is, the more higher the ball will flight.

However, not every golfer created equal. Therefore, swing will change from player to player. Some golfer will always hit the ball higher than others even they are using the same club. Why? Because when the club-face made the impact with the ball, the "effective loft" is what really counts!

Example:

Lets say that my #7 Iron loft is 34 Degree.

I suppost to hit the ball with 34 degree when impacting the ball. However, I rotated my wrist too much open when I am hitting the ball. therefore, the real (effective loft) is actually 39 degree. So now the ball will flight 5 degree higher than what it should be.

34(Original Club Loft) + 5(My wrist too open) = 39(Real effective Loft)

So, if I complain about my balls flight too high, I can try to get a set of iron that is designed stronger(less Loft). In many case, it will be the LT(Low Trajectory) series. Maybe in the LT series, the 7 iron is 30 degree. So with my open wrist hobby, I will get 35 degree effective loft.

Vala! The balls flight about the right high now!

The Ball Flight Laws

Above are the shots that a golfer can create from a swing. There are total 9 different ways of the ball flight.

1st) Pull Hook : Close Face + Outside-In Swing Path
2nd) Pull : Square Face + Outside-In Swing Path
3rd) Hook : Close Face + Inside-Out Swing Path
4th) Draw: Close Face + Straight Swing Path

5th) Pure: Square Face + Straight Swing Path

6th) Fade: Open Face + Straight Swing Path
7th) Slice: Open Face + Outside-In Swing Path
8th) Push: Open Face + Straight Swing Path
9th) Push Slice: Open Face + Inside-Out Swing Path

The direction of the ball fly can be effected by two factors. They both measure in degrees.

1st) The Club-Head (Swing) path/Path of Hand. Which meaning how did the club contact the ball. And there are 3 ways that a "SWING PATH" can be produced. The swing path is measure from usually the distance/track between player's two feet.

a. A Straight Path. This is what every golfer's good swing path. If the Face is Flat when contact. The ball will travel nice and straight.

b. A Path from Out-side to In-side. Usually happened to most of the golfer because the right arm is stronger than left arm. (Right-Handed) Sometimes it can be generated also by "pulling" the club down or "chopping" the club down from the top. More than 80% of the beginners have this type of the swing path. The initial of the ball fly will goto the left side.(right-handed)
c. A path from in-side to Out-side. Usually can see from player that also play other sports that have the pulling out motion. Also from better players will favor in this style of the swing path.The initial of the ball fly will goto the right side.(right-handed)

2nd) The Club-Face Angle. There are basically three way you can impact the ball for the club face angle. OPEN, SQUARE, and CLOSE. However, degree of open and close can be different from swing to swing. The more degree it open, most likely the ball will spin to the open direction more later after the ball fly out.(Fade or Slice). The more degree it close, most likely the ball will spin to the close direction. (draw or hook).


EFFECTIVE LOFT AT IMPACT
This will determine the height the ball will fly. If, at impact, the hands are behind the club-head, the loft will be increased and the ball will fly higher. In another hand, if, at impact, the hands are ahead of the club-head, the loft will be decreased and the ball will fly lower.

SWEET SPOT
This is the focal point of your club-face(usually in the center) and, if struck there, you will get solid contact and maximum distance. Also today, there is a measurement call M.O.I. this is also the measurement of the size of the sweet spot. So, when a golfer hits a off-center shot. Today's high M.O.I. driver will still hit the ball far and not lose much distance.

CLUBHEADSPEED
This will determine the distance your shot will travel with a given club, assuming you make solid contact.

新的高爾夫球球桿打擊的更遠?

嘿! 該換一個新的球桿了, 你的打不遠了!
真的嗎? 為什麼新的才打的比較遠? 難道科技真的進步了這麼多.
我來用以下的表來比較一下這些年來角度做的調整:

男用木桿和鐵桿的桿面角度進化史 – 業界的平均數字
球 桿	1960/1970〈桿面角度〉	1980 (桿面角度)	1990早期〈桿面角度〉	1997年以後〈桿面角度〉
一號鐵桿	17	17	16	16-17
二號鐵桿	20	20	19	18-20
三號鐵桿	24	23	22	20-21
四號鐵桿	28	26	25	23-24
五號鐵桿	32	30	28	26-27
六號鐵桿	36	34	32	30-31
七號鐵桿	40	38	36	34-35
八號鐵桿	44	42	40	38-40
九號鐵桿	48	46	44	42-44
劈起挖起桿	52	50	48	46-48
G 挖起桿	沒有	沒有	52	50-52
沙坑挖起桿	56	56	56	55-56
開球木桿	11	11	10	9-10.5
三號木桿	16	15	15	13-14
五號木桿	22	21	19	17-17
七號木桿	28	27	23	20-21
以上的數字是以大部份廠商的成品為標準, 不同廠牌和樣式會有一些不同.

那我們來比較看看1970 的 7 號鐵桿不就是跟現在的9號差不多? 而且還有一點, 1970的 7 Iron 長度是 36" 而現在的7 Iron確是 37"-38"
所以現在的9 號鐵桿打個跟以前的7號鐵一樣遠. 知道原因了嗎?

我們再來研究一個新的鐵桿. "GAP WEDGE". 這是一個近幾年開始流行的挖起桿. 因為鐵桿的度數越來越低, 所以在PW 和 SW 中造成了一個"斷層" 現今的PW 是 46度, SW 56度. 中央差在10 度左右, 所以需要一個新的之間的挖起桿. "GAP WEDGE" 就是這情況下的產物.

那我需要買新的球桿嗎? 反正不是真的打的比較遠.....真的, 不要小看科技的進步, 其實還是有差的. 新的球頭對大部份打不到中心點的擊球會有較多的幫助. 對這類的擊球, 距離不會失去太多而且方向也不會偏差太遠. 對大部份的球友來說還是會有許多的幫助的.

Why New Clubs hits the ball Further?

So we all know the new irons hit the ball further. But do you know what is the majority reason behind the new "hitting further" secret? This chart should give you an idea about how the Golf Makers of the world play around from the past.

Men's Club Loft Angle for average Brands
Club / Degree	1960/1970	1980〉	Early 1990	After 1997
1 Iron	17	17	16	16-17
2 Iron	20	20	19	18-20
3 Iron	24	23	22	20-21
4 Iron	28	26	25	23-24
5 Iron	32	30	28	26-27
6 Iron	36	34	32	30-31
7 Iron	40	38	36	34-35
8 Iron	44	42	40	38-40
9 Iron	48	46	44	42-44
Pitch Wedge	52	50	48	46-48
Gap Wedge	None	None	52	50-52
Sand Wedge	56	56	56	55-56
Driver	11	11	10	9-10.5
3 Wood	16	15	15	13-14
5 Wood	22	21	19	17-17
7 Wood	28	27	23	20-21
Driver Length	43.5	44	44.5	45-45.5
7 Iron Length	36	36.5	36.5-37	37-38
These are the average specs from different brands. They could be all slightly different due to different models.

As you can see. A 7 Iron from 1970 most likely have Loft Angle of 40 and Length of 36. Now you look at our 9 Iron from today, Loft 42 Degree and Length of 36. Is there something funny here? The club numbers are moving through time or we hitting further everyday?

And why we need a "GAP" wedge now? So from 1970 the gap between my PW and SW is 4 degree. Really! There is not a "big gap" it is quite standard. Look today's Iron. My PW is 46 and my SW is 56. My God! There is 10 degrees inbetween them. I really need something to fit into the gap! That is why!

Ofcause! I know the material changed and Tech really improve. That is also some factor of why we all hit the ball further. But the really improvement of the club is the forgiveness. Today we have a fancy term call M.O.I. (Moment Of Inertia) Which really mean that if I make a "bad" shot. I hit the ball somewhere around my sweet spot. I will not lose too much of distance and the direction of the ball fly will not be off completetly. Woo! That wil save my day somehow right?

So the question is that "SHOLD I GET A NEW SET OF IRONS?" The answer is most likely to be "YES". Because it will increase your happy days because it is really "more forgiving".

"ARE NEW DRIVER HIT THE BALL FURTHER?" The answer is also "YES" because most of the golfer dont hit the ball inthe dead center of the club-face. Therefore, we will find with the new driver, we dont"lose" much distance base from a higher M.O.I.

If you are a professional player. Always hit the ball at the sweet-spot and know what you doing. (like the people you see one TV playing for Million dallor) Keep using the new model of the clubs does not really help them much. They dont really hit the ball further by switching the clubs......Dont forget, playing golf is their job. They just pick the club which give them the most sponsorship money. So, Ernie use his new Callaway Iron now because it is much better than his old clubs? Hmmm.....I am guessing because he gets paid for using them? That is why now some people will be willing to pay for big money to use the same clubs that he used right? You tell me...

揮桿重量 Vs. 球桿重量

揮桿重量 (Swingweight)
揮桿重量測量的方法是以一種特殊的磅秤測量(以下圖畫為例). 找出桿子對稱的平衡點.
平衡點月靠近球頭, Swingweight 越重, 反而則越輕. 而較重的揮桿重量在揮桿時會懹球友
感到更多球頭的重量. 原因是因為球桿的大部份重心較靠近球頭.
我們把球桿的零件分為握把, 桿身, 球頭三大樣. 其他有微小的差異在膠帶, 膠水, 和Ferrule.
在平衡點前的握把與桿身重量統稱為握把重量，平衡點後所有的重量 ( 包括桿頭 ) 稱為桿頭
重量，任何一個配件重量的改變將會影響到揮桿重量。
揮桿重量的單位為一個英文字母加上一個數字，如 C-9 、 D-0 、 D-1 ， D-9 . 以上四樣中
最輕的單位C9， D-9 為最重的單位，以此類推。簡單來說，越接近桿頭的重量越重，揮桿重
量就越重，接近握把的配重越重 , 揮桿重量就會越輕。
通常的情況下男性的桿子會從C9 到 D5, 而女性的會從 C2 到 C9. 在一些情況下, 通常短桿會
比長桿有較重的揮桿重量.

來做一個舉例:
一個七號鐵桿 球頭重 270g, 桿身 125g, 握把 52g, 長度 37" Swing-Weight D2
如果我在握把內部加上一個4g (公克)的鉛帶, Swingweight 就可能變成D1

如果要更改揮桿重量, 以下的公式可能用:

球頭重量(Head) +2gr = +1 swingweight; -2 gr = -1 swingweight.
球桿重量(Shaft) +9 gr = +1 swingweight, -9 gr = -1 swingweight.
握把重量(Grip) +4 gr = -1 swingweight, -4 gr = +1 swingweight.
球桿長度(Length) + ½” = +3 swingweight points, - ½” = -3 swingweight points.
(當然有時膠帶和膠水等東西也會有一些影響)

所以最好的揮桿重量是什麼????
沒有什麼是一定的, 重點是你喜歡什麼重量. 如果你是新球友, 不要想揮桿重量的問題.
先把球打好吧. 如果你已經打的不錯了, 而你在揮桿時如果會有想要感覺較輕或較重的情況
的話, 你就可以找一些高爾夫技師來幫你更改. 又或是你覺得揮桿時有些球桿感覺好, 但是
有些球桿感覺重量怪怪的, 也應該去檢查一下.

球桿重量(Club Weight)
顧名思義是球桿的重量. 理論上來說越輕越好. 打個比方如果給你兩隻球桿
一隻300克, 另外一隻600克. 那一隻可以揮的會比較快? 當然是300克的.
但是如果給你一隻100克的球桿的話, 你可不可以做出完美的揮桿動作? 還是會因為太
輕而反而失去控制力.

Swingweight Of Club Vs. Club Weight

So, There is two "weight" you can find from a golf club. One is the "swingweight" and another is just "weight".
Weight is simple. It is the total weight in "gram" for a club. It is added together from following:
club-head + shaft + grip. (Also ferrule, glue, and tape inside the grip) Usually, an iron should be around from 300g~500g and wood might be from 250g-400g.
Swing-weight in another hand is a measurement of a golf club when it is swung. It is to find out the balancing point of the club. It is measure by C0, C1, C2 ~ C9, D0, D1 ~ D9, E0, E1~ E9.
People mention that heavier swing-weight referring to more toward E, Lighter is toward C.
Usually, a man's club would be from C9~D5 and lady's club will be from C2~C9.
Heavier swing-weight meaning whena golfer swings his club, he feel the head more.

Lets make an example:
Take a club, say a 7-iron. Imagine adding lead tape to the 7-iron. No matter you put the lead at club-head, shaft, or grip. The actual weight of the club will be identical. However, swing-weight will be totally different. if the lead tape is on the club-head, the swing-weight will be heavier because now the balancing point will be more toward to the club-head now. In another hand if the lead tape has been put at the grip, the swing-weight will be lighter because now the balancing point of the club is more toward to the end(grip) now.

The key application of swing-weight is in matching the clubs within a set. You want all your clubs to feel the same weight during the swing.(Especially most of the irons). If you are replacing a club or adding one, you want the new club to match the swing-weight of your current clubs.
Lots of golfer will make the short irons have heavier swing-weight because it can be more easier to lift up the ball since it can feel easier swing into the ground.

So, HOW IMPORTANT IS SWING-WEIGHT?
Well, lots of recreational golfers who fancy themselves equipment "experts" (You know who..) might argue that it is "extremely" important, and for many golfers, they actually might be right.
But the research show that majority of the golfer cannot feel anything different if the measurement is less than Two swing-weight measuring point. Even professional players cannot tell the difference between one swing-weight measurement. However, most people can feel the different once the swing-weight is moving more than 3 measurement.
For example: If your 7-iron swing-weight is C9 and your 6-iron swing-weight is D3.... I am sure you will feel something is weird. Even your distance will be funny because the swing-weight of your irons are big different.
Therefore, if you feel that your irons are giving you weird feeling when you swing different clubs. You should go check them.

HOW ABOUT TOTAL WEIGHT OF THE CLUB?
In theory, the lighter the club. the potential of distance will produced. Why? because the swing-speed can be faster. A person can surely swing a 300gram club faster than a 600gram club right?
That is why most of the driver today use "ultra light weight shaft + Titanium Head + light grip". So I can swing harder and faster with my light club.


COMBINATION OF WEIGHT AND SWING-WEIGHT?
Well, sorry guys..... Golf is personal. You just have to find out yourself. If money is not an object. Doing some good experiment with your club-maker will be a good choice!
In general, a better golfer will toward to lighter swing-weight club and slightly heavier in total weight. (Just most of them. Not everyone!)

My personal opinion.
Beginner Male players - Heavier weight + HeavierSwing-weight.
Reason? Heavier Feel for everything. Easier to "hack" the club!

Easy Players (Teens, Ladies, Senior) Mid-Weight club with Lighter Swing-weight.
Reasons? Less effort to swing. Dont worry about feeling the club-head "dragging" behind.

Better players (12-0 handicap) - Find out what you like!

球頭的Lie 角度跟球飛方向的關係

下面一篇中有三種打擊到球的情況. 第一個是Lie 角度不夠所以當擊到球時, 球頭外面(Toe)離地遠而球頭的內部先著地. 這樣會導致球飛向左方. 反過來說, 如果擊球時球頭外側先著地加上內側離地的話, 球會向右飛出. (以當球面都是朝前並沒有打開或關起時, 之後我會再提到擊球面跟球飛出的方向)
通常造成擊球時球頭不跟地面平行的原因有以下幾種:
1) 站位時離球太遠 ( 球頭外離地面遠), 太近則相反.
2)對打擊者來說, 球桿的長度太短( 球頭外離地面遠), 太長則相反.
3) 揮桿方式不對. 比方說許多用右手太用力擊球者容易揮桿從外而內, 球頭內側先著地.
4) Lie 的角度不對. 比方他的角度已經改變了(打久就多多少少變). 或是跟本就不適合(比方買二手的球具, 之前的使用者是用不同Lie 角度的)

注意: 只要是鐵桿, 它都有可能角度會跑掉. 最好一到兩年檢察一次. 畢竟那只是一塊鐵, 大家不會認為敲來敲去也不會變型或被搬動吧??

通常一些較專業的賣球具的地方都可以幫忙測驗角度, 也可以測試球友擊球時是否跟地面平行. 如果打擊時的Lie 不對, 擊球很難穩定. 請小心.

Club-Face Lie Angle and Swing Direction

Above pictures are three typical style of impact position of the club-face with different lie.
Imaging if a golfer swing back and hit the ball while the face is "too upright lie", the club-face
actually is aiming to the "left-side" even hit on the sweet spot. In another hand, if "too flat lie"
then the ball will actually going to the "right-side".
Lie angle incorrect at impact might caused by few different things or combination of them.
1st) Posture ( Too far away from ball = Too upright Lie)
2nd) Length of Club ( Club too short = Too upright Lie)
3rd) Swing Path (Swing from Out to In with Club-Face Open = Too upright Lie)
4th) Lie Angle Incorrect (The Club-head Lie Angle Off angle)
PS: Please dont tell me you think a club-head made by piece of metal can keep its shape forever............

To check how you made contact with the club. You can goto a local professional clubmaker who has the equipment to test your club. Make sure the club that you use has the right angle for you.
Otherwise, it is almost waste of the time to practice at all.
A club with a right lie angle made for you can always make your game more consistent.

高爾夫球桿子的彎曲(Bend Point)點

第一, 我不太確定Bend Point 的中文是什麼, 所以如果有人可以告訴我正確的
說法請告知. 我是又直譯的方式來說.
桿子的Bend Point就是它在彎曲的時候會在那裡形成的地方. 也有人叫Kick Point (踢起點),
新的說法也叫(Bend Profile). 想像你的小腿, 當你踢東西的時候它就是以膝蓋部位彎曲.
當你在選舉球稈的時候, 有時比較專業的商家會尋問你是否除了軟硬度外(Flex), 你對桿子的彎曲點是否有特別的要求. 而桿子的彎曲點會導致你的擊球的高度不同.

我以以下兩隻桿子來做比方:

1) 9度Loft 的開球桿 65 克重, R-FLEX 正常軟硬度. High Profile(Low Kick)

2)9度Loft 的開球桿 65 克重, R-FLEX 正常軟硬度. Low Profile(High Kick)


同樣的情況下(揮桿速, 角度等都一樣), 第一隻桿子打擊出後球會飛的比較高.
這扯到了一個問題, 到底球比較高好還是底好??
以大部分的球友來說, 球非越高, 應該可以越遠. (Driver 為例)缺點是受到的風向的
影響也會增高. 還有通常海拔高的球場球也飛的較高.. 所以有人在山區開球時發現他
突然打比較遠了就是這個原因. (扯題了..)
本人的建議, 如果揮桿較慢而且希望打擊遠一些的人, 用High Profile的桿身較好.

年長的球友通常會用重量輕, 軟桿, 扭力高, High Profile的球桿. 也就是如此.

Golf Shaft Kickpoint / Bend Profile / Bendpoint

From the Picture Above. The Top is where you hold the club(Grip) and the bottom is where the club-head is. If they are same FLEX, you can see they actually will launch the ball differently because the "bend point" is different.

"Kickpoint" is actually old term shaft design that was used to try to describe how the shaft's overall stiffness or flexibility was distributed over the entire length of the shaft. Today, It will be call Bend Point of Bend Profile.
The most important factor for different bend point result in the trajectory of the ball fly. The reason for that is from the construction of the shaft.
By varying the outer and inner diameters of the shaft, along with the wall thickness in-between at any point along the shaft, we can construct shafts of the same overall stiffness but which differ in where they are more or less stiff.
For example, the factory can produce two shafts both in R flex but with different bending point / bend profile.
Let's say we compare these two drivers:

1st Driver 9.5 degree with 65gram Regular Flex High Profile (Low Kick)

2nd Driver 9.5 degree with 65gram Regular Flex Low Profile (High Kick)


The 1st Driver will actually launch the ball higher due to the Profile of the Shaft.
(If the swing is exactly the same..)

Therefore, most of the drivers designed for Senior, Lady are most likely to have Lighter weight in shaft, softer flex, and higher profile.
Light Weight = easier to swing and can swing faster.
Softer flex = does not require fast speed of the swing.
Higher Profile = Launch the ball higher.

Distance come from the speed of the ball(Club-head speed at impact) and the carry distance(Ball travel time in air).

高爾夫球桿的軟硬度測驗標準 (CPM)

高爾夫球桿的軟硬度測驗標準通常是用CPM 來當測量單位. CPM 是 Cycle Per Minutes 也就是說桿子一分鐘內的擺動數. 越硬的桿身, CPM越高.
例如:
把一個長45" 的Driver 測量出 CPM 275. 那就是 Stiff 硬稈
把一個37"的七號鐵桿測量後得出CPM 320. 那就是Regular 通常的桿

CPM 是以桿子最後(裝握把的)那頭來做測量. 通常許多量身定作的店家都會有可以測量.
把握把處固定在機器上後以擺動球頭處來測量它的擺動度. 但是跟所謂KICK/BEND POINT
確沒有一定的關係. 所以並不能測出球桿擊球的角度(彎曲點). 之後我會再解釋..

有趣的是在定位R, S, A 中. 每一家公司會有些不同. 比方說 Titleist 的Regular 就比Callaway
Regular 的還要硬(CPM較高).

SHAFT FLEX Measurement CPM

The Measurement of Shaft Flex also is determined by CPM (cycles per minute).


The way to measure by this chart. If your CPM with Driver is 240CPM and the length of the driver is 44" Long. The Flex should be A flex. (Senior, Lite) If your 7 Iron is 320CPM and it is 37" Long. The flex for it should be Regular Flex.


Frequency is the measurement of the butt stiffness (stiffness at the grip end) of a particular shaft. For years custom clubfitters have used butt frequency as the measurement tool to compare the specific stiffness between various shafts. The shaft is placed into a frequency analyzer and oscillated either up and down or side to side. A counter on the analyzer calculates the cycles per minute (CPM). The higher the CPM reading, the stiffer the shaft and visa-versa. However, butt frequency does not take into account the tip design of a particular shaft. Therefore it is critical to identify the type of ball flight you desire to achieve and find a shaft with proper tip characteristics to optimize trajectory.

However, there is "No Standard" measurement in Golf. For example, Titleist Stiff Shaft will be much stiffer than Callaway Stiff because Titleist define their stiff CPM measurement different.

GOLF Club Name (Nickname)

Today, people hardly use the term to call different clubs in the bag anymore. However, it is nice to know them in their "real name".

Woods

At the old days, there are 2 and 4 woods. unlike today only D, 3, 5, 7.... Or sometimes you see 3+ and 5+. Actually 3+ is more like a 2 wood.

• [1] Playclub/Driver
• [2] Brassie
• [3] Spoon
• [4] Baffy
• [5] Cleek

Irons

At the old days, there are more 1 and 2 irons. Some of them are even handmade. Ever since the Hybrid(Rescue, Recovery) Club out to the market. The long irons are fading away from the market. However, there are always golfers who can play long iron better than wood and hybrid. In that case, you might find 2 or 1 iron from his/her bag.

• [1] Driving Iron (deep-faced iron with a short head) or Cleek (longer-headed iron with shallow face)
• [2] Mid-Iron
• [3] Mid-Mashie
• [4] Mashie-Iron
• [5] Mashie
• [6] Spade Mashie
• [7] Mashie-Niblick
• [8] Pitching-Niblick
• [9] Niblick
• [Specialized chipping club] Jigger

Wedges

The degree is more like standard degree. However, base from the brand and models of the club. The angle could be different as well. In some irons, all clubs are stronger. Therefore, the PW maybe 45, Gap can be 50, and sand wedge can be 54 or 55.

• [48°] Pitching Wedge (PW)
• [52°] Gap Wedge (GW), Approach Wedge (AW), Dual Wedge (D), Attack Wedge (AW) or Utility Wedge (UW)
• [56°] Sand Wedge (SW)
• [60°] Lob Wedge (LW)

高爾夫球 球桿的重量 與球友的關係

球稈的重量
球稈的重要是用克(gram)來計算, 而通常廠商發表出的重量是
未切之前的重要. 在組裝的時候會切短, 所以會稍輕一些.
通常大部份的廠商並不會把正確重量印在稈身上, 大都是大概的
整數. 比方說 ALDILA 公司的桿子通常以 45, 55, 65, 75, 85
來分類. 但是65並不真正是 65 gram. 而是68grams. 如果要詳細
的重量的話, 要到廠商的資料處查詢.
舉例來說 ALDILA NV 55-R 這個桿子. ALDILA 是牌子, NV 是型號,
55 是重量, R 是正確的Regular 軟硬度.
以物理學而言如果揮桿的力道一樣, 球具一樣, 為一不同處在於
球桿重量的情況下. 球桿越輕, 而揮桿速度會越快. 揮桿速度越快,
擊球後球飛的越遠. 所以理論上越輕的球具可以打越遠, 這也是為
什麼很多新的Driver大頭做的越來越輕.
但是要小心的是有許多球友當他拿到一隻非常輕的球桿時, 他揮
桿的感覺會減少而導致沒辦法正常擊球.
總而言之, 選一個輕但是可以有感覺的球桿最重要. 有許多人當
他用重的球桿反而打的比較好. 更有人用鐵桿的木桿. (老虎就是)
常規來說, 揮桿越快可能用越重的桿子就不會失去控制力.

GOLF SHAFT WEIGHT and Golfer

Shaft Weight is define by the total weight of the "raw shaft" itself. It is measured in grams. Most of the time when a club is purchased, somewhere on the shaft has a printing of number of gram(65 grams, 55 grams etc.). Most of the driver today come with graphite shaft and there are always printing on the shaft that classify the specification including the weight.
For instance, in shaft "ALDILA NV 65-R " Aldila is the brand, NV is the model, R meaning Regular Flex, and 65 is the weight in grams. "ALDILA NV 55-R" will be 10 grams lighter compare to 65-R.
In theory, the lighter the club is the faster the club-head speed base from same force of the energy(Golfer's Swing Energy). Therefore, to make a shaft lighter seems like a great idea to get more distance. That is why there are more and more clubs using lighter weight shafts today. However, lots of golfer actually might "lose the feel" of the club because the club itself is too light. Therefore, choosing a shaft that a golfer can "feel" during the swing is very important. Sometimes a golfer can actually play much better with a heavier shaft. (like Steel shaft in Driver) Typically, a male hitter will love to have something that is heavy in his hand to swing.

GOLF SHAFT : TORQUE 球桿身的扭力

TORQUE OF THE SHAFT:

Sometimes player can see "low torque" or measurement of torque written on the shaft. (torque 3.2) Actually, it means the resistance to the twisting during a golf swing. The torque is measure in "degree". The degree means how much the head actually most likely will turn during the swing. For instance, a shaft with torque of 4.5 will turn most up to 4.5 degree open and close during a complete swing. A higher torque also give a player a softer feel during the impact.
By theory, shaft with lower torque are thought to be higher performance and more forgiving. And with higher torque are thought to be longer in distance because the extra "twist" power.
Most of the more flexible usually has higher torque. The reason is to kick the ball further also provide a softer feel of the impact.
For most of the golfer. A male beginner should use a lower torque for the shaft because usually a man try to "hit it hard" in the swing. Also, a lower torque can help a golfer to "feel the shock" when a impact. A female or senior most likely to use a lite shaft with higher torque because most of them don't want to feel like "hitting something" and "shock the hands". Plus the extra twist "might" help a bit at distance.


高爾夫球 球桿的扭力

桿身扭力“torque”代表球桿的轉幅度(或有些人叫剛硬性)，它的測量方式是角度。扭力值愈低表示球桿〈球頭〉的轉幅度愈小，擊球的安定性愈好(理論上)但是也因此而反震力也較高。而扭力較高的球桿擊中球時，打球者較不會從手上感到震盪，而且理論上有可以有打到較遠的距離。
比方說，一個球桿它的扭力是4.5度, 在上竿的時候球頭會比一個2.5度扭力的打的更開。另外一方面如果打擊到球的那一煞那，如果沒有擊到中心而打到偏外。扭力高的球桿會更容易打出偏外的球路。
通常男性球友剛開始學時最好那扭力較小的桿子。因為可以感到"打擊到球"，也讓那些打的不是很準的球不要偏太多。而女性球友或年長的球友拿扭力較高的球桿可以打的更輕鬆和幫助打更遠。

GOLF SHAFT FLEX 高爾夫球 球桿身的軟硬度

Today, I want to talk about the Shaft for Golf.
Basically, the shaft attributes has following:
(My example using a Titanium Driver Speed Measurement.)

SHAFT FLEX (flexibility) 球桿身軟硬度
Commonly break down into ( J, L, A, R, F, S, X ) 以上是通常可見的軟硬度.

J - Junior Flex. For Junior only. Usually regarding to 8 years old and younger. But not necessary to use it because kids don't really have a proper swing. There will not be too much difference even using a very flexible shaft.
小孩子的軟度. 通常指八歲以下用的. 但並不是一定要用J Flex 因為通常小孩子的揮桿還不穩定, 特意去用J Flex 並沒有太大的不同.
(50mph and below)


L - Ladies Flex, the most flexibility that usually on the market. However, sometimes is also same like the A Flex. However, not every lady like L flex because the wimpy feel.
女性的軟度. 有時跟A是一樣的. 但是許多的女性會覺得L 會稍軟.
(70mph and below)

A - Senior(Lite/Light) Flex. The reason use A is to prevent confusion between Stiff Flex and Senior. Therefore, A is the word it used. A flex usually is the most flexible that for man.
通常是給長青者的軟度. 或是偏慢的揮竿者用的.
(75mph and below)

R- Regular Flex. Well, this is "regular". Therefore, this is for most of the men and some stronger women. Most commonly seen flex. Usually, if the shaft does not have any indication of flex. It is Regular Flex.
正常的軟硬度, 給大部分的球友使用. 包括普遍男性和一些較強壯的女性.
(70-90mph)

F- Firm Flex. This is a flex that usually does not exist in many brands. Only certain brand has the Firm flex. This flex is for player that usually want slightly more control in swing than distance. Typically, a player who has slight fade because the head face open while impacting the ball. A little stiffer in flex can prevent the head from opening more. However, the little more stiffness also decrease some distance.
F 通常並不存在於大多的廠牌, 這種硬度是給一些用Regular 會不穩. 但是Stiff 失去太多距離的球友. 所謂的不穩通常是指球會Fade(一開始往前直飛但之後開始右旋的球). 原因是因為球桿在彎曲時, 導致球頭擊球面稍微打開面向右方. 讓桿身稍為硬一些可以幫助改進這樣的球路. 但是同時會失去一些距離.
(85-100mph)

S - Stiff Flex. This is for those player who swing faster.(Or Think They Are) If a player swing fast but using a flexible shaft, it will be difficult to control the ball fly.
Stiff 是硬桿, 是給一些揮桿速度快的球友. 但有時買的人只是以為自己揮桿快 ^_^. 如果揮桿速度快而用軟桿的話, 會導致不穩. 因為會較容易擊球面開或關, 甚至打到偏上或偏下.
(85-105mph)

X - Extra Stiff Flex. Basically for people who swing REALLY FAST.
超硬桿, 給揮桿超快的球友用的. 一句話就是"硬阿".
(100mph +)

Usually the flex can be find out from the computer measuring device. Most of the golf store should have the device to measure. The key point is to "use the more flexible shaft that you can control" because it means most distance and control.
揮桿速度可以到一些球店或是球場測量. 最好的軟硬度是用"控制的住而最軟的竿". 這樣的話就可以打的又遠而又可以直.

USGTF 課程

2008六月底
我去上了USGTF 的課, 學習了很多教高爾夫球的各類方式. 成功的拿到Level II 的證書, 可惜還沒有拿到Level III. 但是多練習後會更有信心.
我覺得上一個課有沒有學到東西跟教課的老師好不好有許多的關係. 照本宣科的教法對我沒有什麼用. 我是一個喜歡從實踐中學習的人, 所以我特別喜歡用真實例子來教授的老師.
高爾夫球的球友的重點如下

許多的Training Aid 訓練器具是一些連90竿都打不到的人發明的, 是一些標準的理論上有用的器具.

許多教球的方法是以偏蓋全, 不求問為什麼就照樣教受的. 比方說, 為什麼球要擺這裡? 前方的手要伸直? 球竿要抬到那裡等....
如果用力學來分析揮竿的話, 許多書上寫的東西就變成了一些可笑的方式.

教課的老師提到高爾夫球已經傳了幾百年, 球竿也一直進步. 為什麼大家的平均標準竿並沒有什麼進步? 重要的一點就是因為太多的錯誤信息. 許多人自己學錯了就教別人錯的方式. 又或是一些PRO拼命要學生把別人的打法硬塞入他的揮竿中. 好比說TIGER WOODS的揮法是對的, 所以我應該用他的握法, 站法, 揮竿法等. 但是我並不一定有他的身材和體力, 用他的打法可能會讓我自己受傷. 孔老夫子說的對「因才施教，有教無類。」這在高爾夫球裡也一樣, 要以打擊者的身材和身體狀態來調整SWING 才是最好的.
還有大部份球友上課是要可以降低Handicap, 並不一定是要換Swing. 所以以 Lowering Score 來當上課的目的才是最好的. 把學生的揮竿改的跟老虎(TIGER WOODS)一樣並不是一個好的選擇.

現在有了教球和球具技師的知識後, 讓我可以更瞭解高爾夫球.
