平行管，還是錐形管比較好

平行管，還是錐形管比較好？

打鐵桿你要懂的有幾個東西，今天我們來討論桿身這部分。鐵桿鋼管桿身裡有兩種桿身設計：一為平行管，以True Temper為首的一幫桿身設計。另一為過去的Project X的錐形管。放眼望去，鋼管桿身都是這兩種設計，你覺得哪一種好？這個問題是因人而異，但你要決定買哪一種，先瞭解這兩種桿身設計的特性。

先說平行管，它有另一個小名叫竹節管。也就是說，它的外觀長得像竹子一節一節。這也是它獨有的特色。會設計成這樣就是它的桿身口徑是一節一個口徑尺寸。每一節的直徑都不一樣。越接近桿頭，直徑越細！小的直徑主要是讓受力彎曲和桿身反彈效果越手感可以更好！

反之，越靠近握把的桿身直徑越粗。也可以把桿身強度提升。一般來說平行管的使用手感，或桿身回饋來說會比較好，不會讓使用者覺得桿子比較硬，而且桿身可以有更多的桿頭彈力。這樣的設計都運用在不同的桿身重量都適用。

目前平行管的產品有True Temper， N.S. Pro/Nippon shaft, Shimada/島田等品牌。以目前的產品款式是市場的主流。產品的價格也友善。但我個人的經驗，平行管的設計在輕量化桿身上就比較不好。應該說鋼管桿身不該用在輕量化的重量上。

我以前用NS Pro 950，打兩次就立馬換掉。原因就是打出來的球質不穩定、亂飛。側旋偏高，距離變短。但如果用True Temper 100g以上的桿身就不會這樣。我用過S200、 R200、R300、S300不同的重量和硬度，它們的手感和穩定性都值回票價。所以說，平行管選擇100g以上的產品會比較好一點。性能和手感都可以兼顧！

You need to know something about iron shafts before you making the right iron for yourself. There are two kinds of steel iron shaft designs, first one is parallel and the other one is taper. You can see all the steel iron shafts are based on one of these two designs and which one is good for you? It depends on your personal usage and preferences.

Let's talk about these shaft design profile. For the parallel, it looks like bamboo appearance and each section is the same diameter, the good thing for such design is the loading can be smooth and easier. On the other word, it's better feel during the play. You will not feel stiffer in the feedback and the shaft delivers good performance as well.

Nowadays there are many steel shafts using parallel design such as True Temper, Nippon shaft and Shimada. You can see 80% of the retail irons are come with parallel steel shafts. The good thing is the price is friendly for golfers to consider. But the negative part is do not use the light weight steel parallel shaft particularly the weight below 100g.

I should say it is the material advantage and profile on steel shaft to play over 100g shaft weight on iron shaft. You can see there are steel shafts with parallel design weighted under 100g such as Nippon shaft N S pro 950/850/750, but with my experience, the shaft delivers more spins on back and side spins. That makes the shot unstable with less distance.

I used True Temper R200,S200,R300,S300 for various shaft weight and it results great. The steel iron shaft is based on the weight and design to provide the best performance and feel. If you pick the steel shaft under 100g, the performance is going to be unstable sharply. In short, you need to play steel iron shaft with weight 100g, you want the lighter shaft weight below 100g, you should go straight for graphite shaft!

下集開始。

那錐形管呢？錐形管在外觀上就是沒有竹節設計，一管到底，桿身前端到尾巴，像錐形設計。桿身口徑接近桿頭位置是最細。錐形管主要是以Project X這類產品為主。當然True Temper和shimada/島田也有這類產品。但一樣和平行管的問題，它的重量設計低於100g的產品穩定性就不如100g以上。

我必須說基本物理特性和材料學概念。如果你要穩定性好、強度高、可以承受你的力量速度，就直接用鋼管100g以上。別去搞什麼90幾克或80幾克的鋼管桿身。用了才嫌打起來不穩或亂飛！要用100g以內，就直接去看碳纖維桿身，因為揮起來舒服、效果也好、高碳布材質強度也高。穩定性也不差。甚至比鋼管90g要猛。

錐形管的好處在於它的桿身強度要比竹節管要好。在桿身承受使用者的力量/能量，會被桿身一體的結構給壓下來。所以桿身的回饋沒有太多桿身彈力，也就是桿身變形量會相對小。好處就是可以壓制更多側旋和倒旋。穩定性相對高！

因為桿身的設計特性如此，對於使用者喜歡桿身回饋簡單、穩定和小變形量，這樣的產品就是你的白雪公主。 兩種桿身特性都不同，你在選擇上也很簡單、一翻兩瞪眼。所以你問我那個好或哪個適合我？你只要打過就知道你喜歡哪一種？但一定要選桿身重量在100g以上的產品去比較才準。

回饋絕對是這兩種桿身區隔的重要因素。桿身重量也是關鍵。100g～130g都是這兩種桿身的主力。這個區段產品很多，一定會有你適合的東西。所以我把問題再變簡單了，回饋解決後，就是重量。重量以100g為區隔點，你需要什麼或適合哪種桿身也清楚。

桿身很複雜，但從上面的分析和產品物理特性去說明，就可以讓你清楚瞭解。只要把問題一個個取出來，然後逐一分析和解決。最後的答案就在那邊！

How about the taper shaft? It's obvious that the shaft has no step on the appearance and the shaft tip size is small. The project x is the best product on taper, of course, True temper and Shimada have the taper shafts. Golfers can choose your taper through these makers. But taper and parallel are the same, the weight is key. It's better to pick the shaft weight from 100g.

Since steel shaft is strong on loading the power, if you have the power and need to deliver the consistency, you need to use the steel shaft with 100g weight for getting the best performance and consistency. Some golfers are looking for the shaft weights below 100g, that's not going to help. You need to know the iron is for accuracy, if your shaft can't deliver that for you.

If you look for lighter steel shaft below 100g,I would say it's better to select graphite shafts for below 100g products. Since graphite shafts have better material and strong feature on shaft loading the power, if you can't handle heavier shaft, you should get graphite shafts for playing the best results. I have compared with the shafts below 100g with steel shafts and graphite shafts, the graphite shafts' performance, consistency and forgiving are better than steel shafts.

The taper shaft is good on consistency that delivers less spin rates in back and side spins. Since the shaft design can load more power but the feedback is stiffer than parallel shafts. That's why lots of pros are using taper shafts such as project x for gaining the consistency and performance.

People are different as you need to try these two kinds of shafts and find the right shaft for your play. These two kinds of shaft profile is different and easy to identify. There is no exact right or wrong on steel shaft, but you need to know the fundamental of shaft knowledge and feature then get the right one for your play.
