And then, we've got this a Raleigh, 是的,然後我們還準備了這台Raleigh which we bought on eBay, for 90 pounds. 我們在ebay上花了90英鎊(約3600台幣)購買這台車 To be fair to it, it is actually an awful lot of bike 說真的,這個價格可以買的單車很多 for the money, but how much of a handicap is it going to be? 但它會有多少問題呢? You know what mate? 其實我覺得這台車還可以 I actually think it's all right. 除了把帶不是白色的 Apart from the bar tape, that's not white, 但其餘的都還行 but the rest of its all right. 恩...這點很重要 - Yeah. It's pretty much spot on this side. 第一回合 Round number one. 這回合非常簡單,爬坡 - It's simple on this one, climbing. 人跟車子一起對抗這個不算輕鬆的斜坡 Man and machines, against this. 總長只有2公里,平均11%的坡度 Which is actually a particularly uncomfortable climb. 但我覺得大部分的坡大概都有20%以上 Just shy of 2 km long, an average gradient of 11%, 一個非常難騎的坡 which I always think is weird 呃...我還是選那台車好了 because most of it feels like its above 20%. 不不不不,它畢竟在我屁股下 It's a tough one. 所以第一回合的爬坡我還是騎它就好了 Ah, I'll just grab that one for now shall I? 如果你不介意的話 - No, no, no, no, this is mine after all Si, 是啦,因為我知道你會在比較累的時候騎這台車 so I'm going to have first dibs on this. 現在我覺得好多了 For the first ascent, if that's okay? 好啊,沒差啦朋友 It's all right mate. 如果你想這樣做的話 - Yeah, it's all right, 'cause you will be tired 那是你要求的喔 then when you will be riding this one. 喔,我有提到我們要全力以赴嗎? And that one will feel better. 這兩台車在爬坡上主要的差異,就是他們的重量 Okay, that's fine mate, 頂級單車加上Wahoo Element碼表後的重量是7.3公斤 if you want to do it that way 'round. 對於一台搭載碟煞的空氣力學車款來說是非常的出色 It's your call. 而我們選的廉價單車則是重達11.95公斤 - [Matt] Oh, and have we mentioned, 重量差超過50% we're going flat out? 好的,所以你先走 Now the major difference between these two bikes 我會比你晚一分鐘出發 when climbing, it their weight. 沒問題 The Super Bike is a lean and mean 7.3kg, 但我並不期望能趕上你 with a Wahoo Elemnt attached. 準備好了嗎? Remarkable, when you take into consideration that it's an 恩,祝我好運吧 Aero bike, with disc brakes. 我們走吧 And our cheap bike, is a rather weighty 11.95kg, 你看看,真是美妙的動作 a difference of over 50%. (自己倒數) - All right, Si you go first, 第一次測試~哇~吼~ I'm going to give you a minute. 我討厭那個坡!我超級討厭那個坡(喘氣) - Okay. 儘管如此,我還是喜歡這台車 - But I'm not overly hopeful to catch you. 感覺不錯 You know what to do? 主要還是在於它的齒比 - Yeah, alright, wish me luck. 我大盤用34t,飛輪30t,來騎完這個坡 Off we go! 讓我們來看看另一位用競賽齒比的結果如何 - Look at that! Poetry in motion. 他愛死爬坡了對吧?他愛死了 - Beep, beep, beep, boop! 那是我很久沒有的爬坡表現了 The first time, whoa hoa! 不過我甚至不需要特別去注意車子 - Aaahhh, I hate that climb! I absolutely hate that climb. 他表現得非常好 To be fair though, I do like this bike. 我有點被他榨乾 That felt cool! 但我還是使盡了全力 Most importantly of all up there, big range of gears. 一開始還蠻穩定的,但當坡開始陡的時候 I ended up using my lowest, which is 34 at the front, 我還是得使盡全力爬完它 and 30 at the back. 你可以看到我有多辛苦 So we'll see how it goes on the other one, 因為我的車褲上有擤不掉而滴下去的鼻涕 with racier gears. 我的袖套上也有一點 He loves it doesn't he? He loves it! 00:04:11,800 --> 00:04:14,520 換車之後進行第二次測試 - Well, that's my first proper hill climb for a 除了重量之外,還有變速系統的問題 long, long, time but I didn't even need to think 必須得說踩踏上沒有覺得有特別的不同 about the bike, it worked a dream, 即使是便宜的變速系統也非常有效率 it's just me that's a little bit lacking, 只要你保持乾淨的話 but I certainly emptied the tank, 鍊條跟飛輪也是相當的不錯 went a bit steady early on, but when that steep bit, 就像你知道的,我一直有提到這點 pitched up I just had to give it everything just to get up. 兩部車子的齒比範圍則是差不多 - Yeah, you can see how hard I went mate, 即使頂級單車是22速的,而廉價單車是16速 'cause I got a patch of snot on my leg warmer, 雖然Canyon是一部競賽用的公路車 that I cant' get off. 但新一代的Shimano DURA-ACE還是相容11-30t - I got a little bit on my sleeve as well. 兩台車在這方面是一樣的 - Yeah, British hill climbs eh? 好的,第二次測試,我就是在期待這個 - [Si] Run number two then, after a quick bike swap. 你的頂級時刻,我的廉價時光 As well as the weight, there's also the issue of the gears, 上路吧,用盡全力 pedalling doesn't feel particularly different. 我會的 It has to be said. 好了,你可以走了 Even cheaper gears are remarkably efficient. 你看看,多棒啊 As a design, chains and sprockets are fantastic. 00:05:11,140 --> 00:05:13,560 我的老天啊這感覺真的很棒 Just as long as you keep them clean. 有點硬、敏捷 Which as you know, I do mention from time to time. 我很想知道結果 The gear range of the two bikes is broadly similar. 但是,這純粹只是我的體感 Even if our Super Bike has 22 and our Cheap Bike has 16. 這是我比較擔心的部分 And although the Canyon is an out and out race bike, 我們走囉,廉價時光 the new Shimano DURA-ACE has allowed us to fit 第一次 an 11 to 30 cassette, which is just as well, up here. 開始囉,第二次測試 - Okay, run number two, I'm looking forward 車子沒有感受到太大的差異 to this actually, weirdly enough. 有感受到一點重量 - Super Bike time for you, Cheap Bike for me. 設定有點不一樣 - Go on Si, give it all you got mate. 但較便宜的變速系統也是非常有效率 - Oh, will do mate. Off you go. 基於設計、鍊條跟齒片 Look at that, sweet as a nut. 只要你保持乾淨的話,他們運作的很不錯 - Wah hoo! Yeah! 只是我們並不是所有人都有這麼做 Oh my goodness me that feels good! 00:06:31,900 --> 00:06:34,780 我討厭這樣說,但我得說 Like stiff, responsive, I'm intrigued to know the results. 這就像夜晚跟白天一樣 But, purely based on perception, 非常的不同 this is another world I'm afraid. 儘管實際上在陡峭的地方並沒有那麼不同 - Here we go, cheap bike time! 最大的不同在於起身抽車加速時 First time. (不知道意思) Well, here we go, run number two, 套句三屆環法冠軍Greg LeMond的話說 and the bike doesn't feel too much different. 這沒有造成甚麼傷害,你就是騎得很快 Feel the weight a bit, 問題是到底有多快 positions a bit different. 而答案是還真的相差有點多 But even the cheaper gears are remarkably efficient Matt跟我自己都差了快一分鐘 and that was design, the chain and the cogs, 對應起來時間上大概差了10% well it's just great, especially if you keep them clean. 恩,那感覺上怎麼樣? As not all of us presenters do. 畢竟那也非常地重要 - Whoa. 對我來說,很明顯地這台Canyon I hate to say it, but that was, 頂級的單車感覺更快一些 that was like night and day. 反應更快,我必須承認 That was very different. 我花了很多時間站起來抽車 Although, less so in the steep there actually. 而力量的傳達感覺更好 The biggest difference was when getting out of 這台我感覺坐著更舒服,並以不太一樣的方式傳達動力 the seat and accelerating. 只是感覺就很一般,稍微有些停頓 And I managed to stick it in the big ring over the top. 第二回合,隨著今天爬坡測試的結束 Which you see at times. 我們要來個簡單但很重要的測試 Well to paraphrase, three time Tour de France Champion 剎車 Greg LeMond, it doesn't hurt any less, you just go faster. 這個Shimano碟煞推出時 The question is, how much faster? 真的是個震撼彈 And the answer is actually quite a lot wasn't it? 它有你需要的所有力量 Nearly a minute, for both Matt and myself. 但隨著模組的改進 Which corresponds to just about 10% time difference. 意味著你可以用那力量來更快地煞住車子 - Yeah, what about the feeling? 而不是在路上打滑 'Cause that's pretty important too. 而外胎呢? Well for me, obviously, this bike, the Canyon, 他們也是很棒的標準配備 the Super Bike, did feel faster. 馬牌的competition 25C管胎 Far more responsive and I must admit, 這是個非常簡單的測試 I spent a lot more time out of the saddle, 維持時速40公里的下坡狀態 I felt the power was transmitted far better. 然後盡可能地在最短時間內煞住車子 This bike, I felt more comfortable sitting down and 這姿勢的重心分配真優秀 applying the power in a slightly different way. 謝謝啦 It just felt generally, a little bit more sluggish. 沒問題,進展很順利 - [Si] Round number two, with the climbing 5.4公尺 out of the way for today, we've got a simple, 所以標準已經出來了 but very important test. Braking. 而我們的廉價單車又會有甚麼表現? - These Shimano hydraulic breaks are the absolute 樂觀點來說,剎車線相當的滑順 bomb, when it comes to performance. 我花了點時間調整 They've got all the power you need, 歪了一邊的剎車塊 but with added modulation. 不過你會看到我按住剎車時 Meaning, you can use that power to stop, far quicker, 卡鉗本身實際上有相當大的歪斜 rather than skidding down the road. 意思是你可能會損失一點力量 And the tyres? 而且你的調整又會沒用 Well they're gold standard as well. 而且我還偷偷地懷疑 Continental Competition, 25 mil, tubulars. 這些剎車皮是非常硬的 - [Matt] It's a pretty simple test, riding at 這意味著他們可以使用的比較久 40kmph, downhill, and then trying to stop 但就沒有辦法讓我們快速地慢下來 as quickly as possible. 不過,我還是要來場測試 - Woof, the weight distribution, that was impressive. 00:09:15,800 --> 00:09:17,700 請讓那輛單車維持穩定 - Thanks mate. 抱歉,Matt - That's all right, went well. 00:09:19,720 --> 00:09:21,300 5.4, well 5 and a half, 5.4 so 5 metres 40, 5.40. 00:09:23,060 --> 00:09:25,020 10.5公尺 - So the markers been laid down, 所以我們有5.4公尺和10.5公尺的紀錄 how is our cheap bike gonna fare? 是的,大概停在兩倍的煞車距離 Well, on the positive side, the cables are super smooth. 結果都出來了 Loads of life left in the pads, 而我可以跟你說,這兩台車的剎車距離 and I have spent time setting them up. 幾乎是100%的不同 However, you'll see if I squish on the lever, 我的意思是,那我們公平點 there's quite a lot of flex actually in the calliper itself, Raleigh煞得也足夠安全 meaning that you can lose a bit of power, 但是Canyon的剎車力道 and you're going to lose modulation. 則是令人印象深刻 And, I've got a sneaking suspicion, 恩,那是相當大的差別 that these pads are really hard compound. 無法否認這是一場人為的測試 Meaning that they're going to last a super long time. 所以在實際騎車的時候 But, they're not actually going 你不會有那麼多需要緊急剎車的時候 to slow us down very quickly. 總之希望不要有 Still, I'm going to give it a good go. 但你必須知道不是嗎? - Ooph. 如果在整趟騎乘的過程中 - Just keep that bike steady please, Si. 即使剛到路口或下坡時出現這種差異 - Sorry Matt, sorry. 你會認為這有相當大的影響 - Thanks Mate. 不是嗎? - 10 Bang on, 10.5. 或你將會這樣認為 - 10.5, so we have 5... 第三個挑戰,下坡 - 10.5 metres 現在帶上我們的剎車知識 - So we have 5.4 and 10.5, ahhh... 來想想是那些因素可以加強這台車下坡的表現 - Yeah so, roughly stopped at double the stopping distance. 如果更好的剎車效能會讓我們速度更快嗎? Wow Si, the results are in. 改版增強後的空氣力學會更有幫助嗎? And I can tell you, there's nearly 100% difference 是的,這會相當有趣不是嗎? in the stopping distances of the two bikes. 現在你知道我們現場並沒有 I mean, let's be fair. 一座可供下坡的高山 The Raleigh, it stopped safe enough 但這條路也是相當不錯的選擇 - Yeah, yeah. 總共3公里長,平均坡度5% - But the stopping power of the Canyon 好了不要在背後偷笑 is mightily impressive. 這是我們目前最好的了 - Yeah. There was a significant difference. 因為這是一般道路所以我們不會瓦數全開催下去 Admittedly, this is quite a controlled test, 而且我們也不是肖年仔了 so there's not going to be that many occasions 儘管如此,我想我們還是來看看我們怎麼進行 where you'd be doing an emergency stop in real life. 但很明顯的,我要再一次騎這台頂級單車 Well, hopefully not anyway. 等會見囉Si But you've go to wonder, haven't you? 好了,頂級單車下坡去 That if that difference over the course of the whole ride, 我們走吧 even just coming up to junctions and on descents, 喔不!我沒有上到卡 and things, you'd have thought that would have 好了,我們走吧 quite a big effect, wouldn't you? 在一台我不熟悉的單車上 Or will it? 騎我熟悉的下坡 - Challenge number three. Descending. 不太好的剎車,但我們給他一點機會吧 Now armed with our braking knowledge, 差了25秒 just how are these bikes going to stack up? 真是令人不可置信 Will the added confidence of better braking make us faster? 好的,那讓我們來看一下這台車 Will the improved aerodynamics help as well? 在下坡時它的空氣力學造型 - Yeah. It's going to be interesting isn't it? 是非常重要的一點 Now you know that we don't exactly have any Alpine 而且下坡時有點逆風 descents on our doorstop, 但是,碟煞非常的給力 but this one is pretty good. 在經過轉彎時給我很大的信心 3 km long, an average gradient of 5%. 與一般的剎車相比我可以更晚一點按煞車 All right, stop laughing at the back. 而且即使在下雨的時候也很棒 It's the best we've got okay? 所以,空氣力學造型跟這些絕佳有力的剎車 We're not going to go flat out because it's open roads 相當有用 and we are of course getting old, but nevertheless, 恩...但我還是無法相信只差25秒 I think we should see how we get on. 關於這個,我上了最重的齒比但還是太輕 - But significantly, I get to go on the Super Bike again. 所以我就沒持續踩踏了 See you in a bit Si, hee hee. 而我有一直再踩,因為我的齒比比你重 Okay, Super Bike run, downhill. 我們需要把這個也列入考量 Here we go, oh no! I'm not clipped in! 是啊,是啊 - Okay, here we go. A descent I know well. 但是...25秒耶 On a bike I'm not very familiar with. 我並沒有期待這一點耶 Poor brakes, but let's give it a nudge. 我並沒有期待 - 25 seconds. 這是另一個殘酷的簡單測試 - I cannot believe that. Literally. 使盡全力地騎10公里遠 - Well, lets have a little look at this bike though, 到目前為止,這兩台單車的差異都很重要 aerodynamics have got to play a big part. 而我想這差距是沒辦法逾越的 - Yeah. Yeah. 但我有種預感 - Okay, on that descent. There's no... 在這個回合,頂級單車將使出殺手鐧 And there was a bit of a headwind on the descent. 雖然你在你的Elemnt Bolt碼表上 But, disc brakes. 已經節省了1.5瓦 So much power, they give me so much confidence 恩...這不能被忽略掉 going into those corners. 加1.5瓦回來吧 I could brake, relatively late compared to using 那會比我們想像的更好 normal calliper brakes. 為什麼我會有預感 And even in these wet conditions as well. 這將會是很大的差距呢? So, yeah, aerodynamics and these 首先,因為這是最長的一個挑戰 wonderful, powerful brakes too. 所以差距會變得更大 - Yeah. I still can't believe 25 seconds. 而且空氣力學造型是非常重要的一點 There were a couple points where I, I ran out of gears 甚至比車子的重量還要更重要 so I just free wheeled. 除了真的很陡峭的爬坡之外 - And I did pedal. I've got bigger gears than you. 在實際情況下都是如此 We need to add that into the mix as well. 但無可否認車手本身就是空氣阻力中 - Yeah, yeah, you do. But....25 seconds! 阻力最大的一部分 I was not expecting that mate. 而我在廉價單車上也可以維持 I was not expecting that. 一個很棒的低風阻姿勢 That's right. 所以你不需要在這一塊上面花甚麼錢 It's another brutally simple test. 我的車衣也是一樣,相當的貼身減少阻力 Ride 10 km as fast as we possibly can. 但是單車的差距仍然相當地明顯 Now so far, the differences between these two bikes 低框及32根幅條造成了一些空氣擾流 have been significant, but not, I think, insurmountable. 輪胎也硬生生地撞擊著空氣 But I just have a hunch that maybe the Super Bike, 而完全沒有辦法平順的穿過它 is just going to land the killer blow on this one. (自己倒數) - Although, you've got a 1.5 watt saving, 你漏掉了一拍!你才數了四下 on your Elemnt Bolt there. 喔,抱歉 - Yep, that's not to be sniffed at. 總之,他出發了 Pulled 1.5 watts back. 好了輪到我 - It could be closer than we think. 第一次測試 Why do I have a hunch that this is going 我跟你說 to be a big one then? 你看起來像掉進深淵裡 Well, firstly, it's going to be the longest challenge 這整件事最有趣的地方 so the gaps are likely to be larger. 其實也是最困擾我的一件事 But aerodynamics are incredibly important in cycling. 吐氣,我的朋友 Much more so than bike weight. 最困擾我的事就是 In almost all instances in fact, 我沒有辦法踩到最舒適的齒比 except for really steep climbs. 因為他只有8速 The rider admittedly makes up the largest 我知道這聽起來很愚蠢 component of total aerodynamic drag. 但我要不是踩太慢,不然就是踩太快 And I can actually get into a really good position 這不是甚麼太嚴重的事 on the Cheap Bike, so that's not something 但在你全力衝刺時,的確會有一點小在意 you have to pay for at all. 00:14:33,160 --> 00:14:34,797 我真的用盡了我的全力 My clothing is also the same, super aero in fact. 只是這台車 However, the difference in the bike is still 我真的不太需要去注意這台車 hugely significant. 他的齒比非常好 The shallow wheels and 32 spokes, cause a lot of turbulence. 我就是覺得很棒 The round tubes too, punch a hole through the air 現在我的速度並沒有特別快 and it doesn't smooth air flow around it at all. 但這台車真的很快,感覺他就是為此生 - Beep, beep, boop. 所以我們要下一輪了嗎?我現在好絕望 You missed a beep! That was only four! 好吧... - Oh, sorry! 如果廉價單車的低框輪組 - Anyway, he's off! 跟幅條造成了重拖的感覺 - Okay, here we go. Beep, beep, beep, boop. 那到底Shimano C40輪組的秘密是什麼? First time again. 這輪組的幅條比較少 - I'll tell you what... 前輪16根,後輪21根 - You look like you went deep. 但主要的阻力減少還是來自於輪框 The funny thing about all of this, 碳纖維製的高框輪框 is actually the thing that bothered me the most. 可以更符合空氣力學 Let it out mate, let it out. 寬28mm的輪框 The thing that bothered me the most, 可以讓空氣從輪胎經過輪框時 was I couldn't get the right gear. 減少更多的擾動 'Cause it's only 8 speed. 而輪框的造型則呈現圓弧狀 I know it sounds stupid, but I was either pedalling 而這代表著正向以及側向的造型都更符合空氣力學 too slowly or too fast. 所以會降低風阻係數 And like, it's not a biggie, but it does wear 你準備好了嗎? on you mind a little bit when you... 去吧 Full of gas? 好喔 - Yeah, but... 輪到這台車的第一次了 I went pretty much flat out there mate. 計時賽最可怕了對吧? That one, but there's no... 是啊 The bike, I didn't really have to think about the bike. 但是至少騎這台車的時候快多了 The gear ratios are fine. 我還不知道確卻時間到底差了多少 Bottom of the block, just felt good, and it felt, I'm not 但是看了一下碼錶 particularly quick these days, but this bike 整趟時速大概差了每小時三到五公里 is pretty quick and it felt like it was doing the job, so. 那非常的多對吧? - So mate, can I have a go please? I'm desperate. 讓我們面對這事實 - All right. 嗯,我對這變速沒什麼太大的問題 - [Matt] If the Cheap Bike shallow wheels and 我就是上了大盤踩 numerous spokes cause a stack of drag. 踩那個令人覺得不想面對的部分 What's the secret of the Shimano C40's? 只是進彎到出彎時,我還是花了一點力氣 Well, there are fewer spokes, 那時我需要慢一點,不過會有點遲緩的感覺 just 16 and 21 on front and back. 但一旦回到該有的位置時 But the main reduction in drag, stems from the rims. 它的速度就會帶上來 Deep sections are made out of carbon fibre to allow 雖然沒有像Canyon的單車那般精美跟有型,但... for the specific wind sheeting shape. 所以你不會來評論我的雙腿吧? The rim is 28 mm wide, so that there's minimal 哦不,他們很漂亮,精美又細緻 disturbance of air as it transitions 恩謝啦 from the tyre to the rim. 不過這真的是一台良駒 And the shape of the rim itself is called toroidal, 它是啊,我是指... that means its aerodynamic on both 我不知道你的能力,但我的均速 the so-called leading edge but then also 是每小時40公里 on the trailing edge, so as the air meets 就算用的是一台19英鎊的單車,那還是相當厲害的數值 the second side of the wheel. 00:16:47,800 --> 00:16:49,420 相當艱難的一天,不是嗎? - You ready mate? 喔絕對是的 - Go for it mate! 結果呢,也不意外地 - Okay. 我們的頂級單車還是相當勝出的 - Beep, beep, beep, boop. He's in again, first time. 爬坡更快、剎車更快、下坡也很快 - Time trial is horrible it? 而計時賽也很快 - It is isn't it. 用百分比來說,你認為哪個部分 But at least it was over quicker on this one. 最需要來個改進呢? I don't actually know exactly what the time difference was. 我覺得實際上是剎車的部分 But just looking at the Wahoo, 因為只需要幾秒鐘和那麼一點距離 it looked like, it was between about 3 and 5 km per hour Shimano的碟煞 difference at all times. 就可以比一般的剎車還要 Which is massive isn't it? 多上100%的效能 Let's face it. 那不僅僅是百分比上的增加 - Yeah. I didn't have a problem with the gears, 而是從性能的角度上來看 I just tended to hoof the big one around, 這可以保住你的小命 around that dodgy corner, that was, 或至少讓你在騎乘時,遠離一些非常危險的情況 it just took me awhile to get this one going. 那為了有更好的剎車表現 From the turn, and from out of those bends 你需要花很多錢嗎? we have to slow down, that's a little bit sluggish, 我不覺得你需要做這種事 but once you got dialled into position, 事實上我強烈的懷疑 it was a quick as it could go, but clearly 你只要有一台配備Shimano Sora系統的車子 not as beautifully sculpted and shaped as the Canyon, but... 就可以縮短與DURA-ACE碟煞系統間的差距 - So, you're not going to talk about my legs then? 所以如果你有一些廉價的剎車的話 - Oh no, they are pretty, beautifully sculpted... 那就花點小錢把他們換掉吧 - Yeah thanks. 這將會是非常有感的升級 - Yeah, but no, pretty good work horse this. 絕對是的,所以下一個是? - It is, yeah, I mean... 空氣力學造型,不管是下坡還是計時賽 Like, I don't know about you but I think my average 它的表現都非常的耀眼 is about 40 km per hour. 但是對我來說,它的下坡表現 - That's still pretty respectable in a 19 pound bike. 真的有讓我一點驚艷到 - Yep. 是的,在頂級單車跟廉價單車之間 that turned into quite tough day didn't it? 這部分有著15%左右的差距 - It certainly did. 當然在下坡的時候,就像你看到的 - Right. 我們會一直含著剎車 Results then, unsurprisingly perhaps, 但到了計時賽的部分時 we've just seen a clean sweep 空氣力學造型毫無疑問地有著影響力 of victories for our Super Bike. 但我想壞消息是 It climbed faster, it braked faster, it descended faster 空力輪組跟空力車架並不會很便宜 and it time trialled faster. 所以在這種情況下 Which though do you think was the biggest area of 廉價單車真的是蠻劣勢的 improvement in percentage terms? 保守來說,如果你在意的是速度的話 - It was actually the braking. 不要騎它去做計時賽 So in just a handful of seconds, 對千萬不要,如果你想參加比賽 and in just a few short metres the Shimano hydraulic 那就參加一般的公路車比賽就好 disc brakes out perform the regular calliper brakes, 因為如果你有聰明的戰術 by a rather whopping 100%. 跟一雙強壯的雙腿 That's not just a significant increase in percentage, 那麼在主集團中 but from a performance perspective, 你騎著一台非空力車的缺點就會 that could actually save your life, 非常明顯地降低很多 or at least get you out of a very difficult situation 所以還是在你的姿勢上好好下功夫吧 out on the road. 如果需要的話,更換你的單車零件 - Do you need to spend loads of money though? 可以讓你感覺快到要飛起來了 To get great braking performance? 所以,關於爬坡呢? I don't think you do. 在我們測試中的那個 In fact I strongly suspect that a bike 殘忍又陡峭的爬坡上 with Shimano Sora callipers on would close the gap 兩台車之間的差距大概在10%左右 to those DURA-ACE hydraulic discs quite significantly. 所以這顯示出超過4.5公斤 So actually if you do have cheaper callipers, 還是造成了不小的差別 then spending a little bit to replace them 是啊,而且值得一提的是 could well be a really, really intelligent upgrade. 兩台車就像兩支完全不同的野獸 - Absolutely. So Si, what is next? 恩...相差甚遠 Aerodynamics, well both descending and timed trial 所以你可以了解 the performances were pretty illuminating but, 為什麼人人都在追求輕量化的單車 for me, the descending did catch me 如果你喜歡爬陡峭的坡的話 a little bit by surprise. 那真的有很大的不同 - Yeah, there was a 15% difference on average, 你知道嗎? between the Super Bike and the Cheap Bike. 如果要我們誠實地說 Now, on the descent, of course, as we've just seen, 我個人真的希望 the brakes will have been responsible for a chunk 兩台單車間的差距不是那麼的顯著 of that time, but down to the aerodynamics have 但事實是頂級的單車真的在不同的層級上 an effect and certainly in the time trial they did. 它就是很快 - The bad news I'm afraid though, is that aero wheels 真的,那我們下一個該看什麼部分 and aero frames don't come cheap. 你覺得要花多少的錢 So in this instance, 才可以縮小這個差距? the Cheap Bike was at a real distinct disadvantage. 500歐元(17600台幣)? Although, in it's defence, if it's speed that your craving, 1000美金(30000台幣)? on that bike, don't do TT's. 2000英鎊(80000台幣)? - No exactly, if you want to race, then race 恩 bunch events instead like a road race. 在我們開始討論這個之前 Because if you've got some shrewd tactics 我想我們還是有一個重要的點要表示 and some strong legs. 那就是我們的廉價單車 Then the disadvantage of riding an un-aerodynamic bike 還是一台很不錯的小車是吧 will be lessend really significantly 這裏有兩點基本的部分 when you're riding in a peloton. 首先,在騎乘上它還是很安全的 So work on your body position, 第二,作為公路車它還是蠻有趣的 maybe even tail your cycling kit, if need be, 恩騎著它還是有蠻多樂趣的 and you will be able to fly. 所以如果你有一台廉價、入門的單車 - So what about the climbing then? 你還是不需要對它感到灰心 So in that short rather brutally, steep climb 它不應該總是針對關於自行車的等級 that we did our tests on. 是的,那絕對沒錯 The difference between the two bikes was around 10%. 不管我們騎什麼車,我們都在同一條路上 So it just shows that over 4.5 kg, 所以檢查一下你有訂閱GCN的頻道 makes a massive difference. 我們都是同一條路上的一份子 - Yeah, it does and it's also worth saying, isn't it, that 要訂閱只需要點一下這顆地球 those two bikes felt like completely different animals. 完全不用錢 Like chalk and cheese. 另外,一些關於重量有多重要的科學影片 And so you can really see why people get obsessed 不如就點一下這裡 about lightweight. 看看我跟Dan在安道爾做的實驗 If you like steep climbs. 恩,背著你的大背包 It does make a difference. 對,大背包 You know what mate? 或要來看一下關於Matt的頂級單車 If we're being completely honest, 特別是車上的Shimano DURA-ACE 9170套件 I genuinely was hoping that the difference 點一下下面這邊 between these two bikes wasn't going to be quite 另外別忘了按讚跟分享 so significant. But the fact is, the Super Bike is in a different league. It's just faster, period. - True, so what should we look at next then. Well how much do you think it's going to cost to start to really narrow that gap? 500 euros? - $1,000.00? - $2,000.00 pounds? Yeah. - Before we do get on to that though. I think there is one last important point that we should address, and that is that our Cheap Bike, is still a great little bike, isn't it? It takes two fundamental points. Firstly, it's safe to ride and secondly, being a road bike, it's just great fun. - Yeah, it was a lot of fun to ride. So you shouldn't get disheartened about this at all, if you have a cheaper, entry level bike. It shouldn't always be about the bike. - Yeah, that's absolutely right. We are all part of the same tribe no matter what we ride. So, on that note, do make sure you subscribe to GCN. We're all part of the same tribe. To do so, just click on the globe, it's completely free. - Now for another, sort of science-y video about how important weight is, how about clicking, just down here when me and Dan did that very test in Andorra. - Yeah, wearing your fat rucksacks. - It was fat rucksacks. - Yeah, or to see a little bit more about Matt's Super Bike, and in particular his Shimano, DURA-ACE 9170, groupset, click just down there. - And don't forget to like and share.
