Giant Bicycles is one of the world's largest bicycle manufacturers. 捷安特是全球規模數一數二的自行車製造商。
And in this week's Art of Movement, 在本週《動的藝術》單元中，
we go inside the company's main production facility in Taiwan and take a look at their unique and high-end production techniques. 我們要進入該公司位於台灣的主要生產廠房，來看看他們既獨特又尖端的生產技術。
Round and round, up and down, it's a simple movement -- one pedal at a time, one foot in front of the other. 一圈又一圈，一上又一下，這是個簡單的動作，一次踩一下踏板，雙腳一前一後。
But it's just equipment to help you to enjoy more. 這不過是有助於讓你更樂在其中的工具罷了。
But for cyclists with the drive to turn that motion into speed, a bicycle is much more. 但是對於一心想要把那樣的動作轉化為速度的自行車手而言，一台自行車遠遠不止於此。
Whenever I get on a bicycle, I always feel very free and everything disappear[s], only you and the road in front of you. 每次我騎上自行車，總會感覺非常自在，什麼都消失了，只剩下自己還有我前方的道路。
I'm Tony Lo, CEO of Giant. This is my bike. 我是羅祥安，捷安特的執行長，這是我的自行車。
Giant, based in Taiwan, turns out more than six million bikes a year. 總部設在台灣的捷安特，一年生產超過六百萬輛自行車。
And Lo, who takes to the roads for his 35-kilometer commute, says this bike, 而每天上路通勤三十五公里的羅祥安，說這輛自行車，
the Propel Advance[d] SL -- or super light -- is the most aerodynamic in the world. 也就是 Propel Advanced SL 超輕量自行車，是全球最符合空氣力學效益的自行車。
It carries a hefty five-figure price tag, but on its own, the frame weighs less than a kilo. 它的價格高達美金五位數，但是它車架本身的重量還不到一公斤。
You want it very light and you want it very strong, but you also want the strength or stiffness [to be] only at where you want it. 你會希望它非常輕又非常堅固，但是你也希望它的強度和剛度達到你理想中的水準。
And in the cycling world, Giant and other bike makers turn to one material to achieve that balance -- carbon fiber. 在自行車界，捷安特和其他自行車製造商選擇用一種材料來達到那種平衡——碳纖維。
Finding that feeling of flying down a road starts here at Giant headquarters with a different kind of movement. 追尋那種在路上飛馳而過的感覺，要從捷安特總部這裡的另一種動作中開始。
In the loom room, carbon fiber strands -- a petroleum product -- are bonded together by what looks like an oversized sewing machine. 在編織室裡，碳纖維絲束——這是一種石油產品——被看起來像是一台超大縫紉機的機器給束在一塊兒，
Each strand is thinner than human hair and every square centimeter of each sheet contains thousands of strands. 每絲碳纖維都比人的頭髮還細，而每平方公分的碳纖維片中就含有幾千絲碳纖維。
From there, it's on to cutting -- computerized machines with razor-edge precision spitting out thousands of pieces in all shapes and sizes, 下來就要進行切割，電腦設定的機器，像雷射般精準地切割出數千片碳纖維片，各種形狀大小都有，
some stronger than other[s], and each with a predetermined position that leaves no room for error. 有些硬度較高，每一片都已經預先設定好位置，不容一點差錯。
You know, all your pedal is in the bottom bracket. So, that's where you want it very, very strong -- what we call the PowerCore. 所有踏板都位在五通管上，所以那邊要做得非常堅固，我們稱之為 PowerCore。
But in the backside, you want it to be a bit soft, so [it doesn't] feel so harsh. 但是在後半段的地方，又會希望能夠稍微軟一點，才不會感覺很僵硬。
Everything about designing bicycles [is what] I love. 所有和自行車設計有關的事我都喜歡。
[Every] design affects function; [every] function affects performances. 每一個設計都會影響功能，每一項功能都會影響表現。
Just upstairs from the factory floor, the art of engineering a carbon-fiber bike comes into play. 在工廠的二樓，設計製造出一台碳纖維自行車的技術在此施展。
This particular model was tweaked 88 times. 光是這款車型就微調修改了八十八次。
A race machine, so it's about the stiffness; it's about transmission. 這是一台競速車，所以它必須強調剛性和變速性。
Everything is included within those 88. 一切都包括在那八十八次修改中。
Once the carbon-fiber frames are baked in these ovens, they have to stand up to scrutiny, 等到碳纖維車架在這些烤爐內成形，它們還必須經得起詳細檢測，
in this case a series of movements simulating a ride -- small, large and even downright aggressive. 以這個車架為例，它要經過一連串模擬騎乘過程中大大小小、甚至異常激烈的震動測試。
Many of those frames are also scanned for imperfections. 那些車架中有許多還要透過掃瞄的方式來尋找瑕疵。
And while the computer says one thing, more dynamic testing might reveal the unexpected. 雖然電腦說的是一回事，但更多多樣的測試可能會透露出一些意想不到的狀況。
Aerodynamic[s] [are] hard to control. That's its nature. 空氣力學的狀況很難掌握，這就是它的本質。
Proof that the art behind shaving a few seconds off race time, 這些都在在證明了，無論是將競速成績削減幾秒鐘，
or just enjoying the breeze during a Sunday ride, is always a work in progress. 或只是單純在星期天騎車享受微風吹拂，其背後的技術研發都一直持續進行著。
