其實自行車就是這樣了，在很多地方聚沙成塔。換大導輪省1W，換空力一體車把省2W，換碳纖空力輻條輪組省5W，這樣方方面面可能就省10W了。40KM/h可以省10W的話就算是對一般人也有感了。
可惜我鈔能力不足，還沒堆成塔就只留一盤散沙 🤣🤣🤣🫣🫣
加下加下加到20 就正啦
師兄啲片真係好高質。希望有機會分享下輪組高低框同特性(影片SL7轉用enve🤤)
多謝支持！ 都係一個好題材 👍🏻 不過我換enve 呢件事唔好諗太多… 只係我由舊車攞過黎 😆😆 roval 我都仲有用
自己都用緊大轆仔！原來有咁多理論！又加深了解啦😄
謝謝專業介紹👍🏼👍🏼🤓🤓
我都係半桶水，周圍睇資料同埋問資深人士先知有咁多學問！ 如有不當請大家指點 👍🏻👍🏻
第一次看呢個頻道 我覺得好好 非常清晰 解答不模糊
Thank you! 🥰🥰
慳得一watt係一watt🥲 正如係人都知減肥比買部較輕d既車有效率得多
突破盲腸！
會補時繼續支持
I did not understand a word you said. But I agree with every word of it. When someone talks about the benefits of these devices it makes about as much sense as you just made.
Hahaha sounds about right ;)
多謝分享(對我來說就係提升心理馬力哈哈,等自己踩快D)
心靈馬力都好重要 😝😝
岩岩想搵大導輪既資料就見到師兄講解, 解釋得非常清晰, 希望講多D呢D單車都市傳說 XD
多謝！ hahaha 睇吓有冇機會再深入探討呢啲傳說啦～ 😇
Hello Daryl～你解開咗好多人嘅心結
多謝大師～ 😘😘😘
I feel a good quality bottom bracket gives a better feeling than opsw or ceramic jockey wheels replacements like tacx. I can feel the difference but having a solid bottom bracket with good quality bearings really helps you transfer power or get that extra rpm in cadence.
Will you do a feature on bottom brackets?
Maybe for fun you can do a blind ‘taste test’ so a rider can try to feel what they prefer or even notice, between stock, opsw or bb.
Keep up the content!
Thanks dude, that's a really interesting idea! Intuitively I think BB would yield bigger differences too but who knows!
@@DarylSeanChan please try so we can all find out! 👍
If you can get Mr Velo involved you can use my bike with Hambini BB as a test bike. He’s installed them before so I would trust he would exchange for other BB professionally.
Thanks man for the generous offer! We'll see what we can do further down the road! :)
Thanks for the video bro, on it for aesthetics. Going for AbosluteBlack hollow cage, have you used one and thoughts on it?
Thanks dude! Unfortunately I haven't heard much about the AB... Hope you can share when you try it!
用緊淘寶大碌仔，用落唔覺有分別，但心靈馬力慳咗50w
50w 咁真係抵買賺watts賺到笑 🤣🤣
第一次用左TRIPEAK 已經感覺好好啦,轉咗套電變之後。忍痛試下CS先，發覺效果更好，冇得講。一分錢一分貨。最主要係睇下自己budget。
真啊，就係睇budget，有又何妨玩吓！
剛剛想拍下淘寶的大導輪,好彩看完你的文章可以打消了,謝謝師兄~
買咩都冇所謂，最緊要做精明消費者～ 👍🏻👍🏻
感謝你分享技術教學。
Thanks man!
昂貴大轆仔⚙️，我就得個睇😵，支持Daryl仔👍🏼
係真係好貴 😆
@@DarylSeanChan 濕濕碎啦你😏 唔好理人話有冇用， 轉得順， 用得開心 就ok啦
其實都係有機會用我先用...唔係我都可能用返原裝 🤣
好清晰！啲專有名詞用返英文真係清楚易明好多！
有時真係好難翻譯 🤣🤣
雖然無踩車，但聽落學到嘢！💪
Thank you! 🥳🥳
OSPW definitely look dope and gives your ride some bling. But I'm thinking it also creates some aero drag which negates the watt gains it claims it provides *shrug*. I probably will still get one or maybe just upgrade the pulley wheels and keep the stock cage. Great review Daryl!
Thanks James! I think that would be a wise way to upgrade 👍🏻👍🏻
@@DarylSeanChan Hey Daryl, forgot to ask where did you get your Direct-Mount Derailleur Hanger?
我最近都裝左Nova Ride大導輪, 講真又感覺唔到有幾慳到力, 不過部車靚仔左好多已經值回票價~~
真，其實真係外觀行先 👍🏻👍🏻
非常清析
多謝支持n
勤保養鏈條上鏈條臘或用高等輕量鏈條或許比這個有效
絕對是！ 我個人覺得大導輪是最後才去考慮優化的部位，有其他更高CP值的地方～
會唔會出片講下GRX 系統🧐 同佢既各樣升級
好想知踩開road bike 既師兄對GRX 有咩睇法...
利申：踩緊gravel bike
多謝你既提議！ 如果他朝一日可以去返旅行都想試下gravel... 🥲🥲
都係心理作用居多，睇落係型過原廠好多嘅，但值唔值得為咗慳果2w力走去花幾千升級就真係見人見智……
我仲諗緊換唔換好，睇完你呢條片後我都係覺得算吧啦，維持原裝好嘞。
都係嗰句…唔係有得試我會繼續用原裝 😳😳
將由ceramicspeed 轉會 > slf-motion
wow 😯😯 求用後感對比分別
改完慳嗰1-2w（都冇🙈），用同樣嘅錢改其他嘢仲好
說出重點了～
睇哂17分鐘, 學左好多野🤩
多謝豚長～ 下次再一齊踩啦！
多謝分享及介紹，請問何時有FAVERO ASSIOMA 分享及介紹 。🙇
Thank you! 俾啲時間我整理思緒 🙏🏻🤣
@@DarylSeanChan 等你出埋review 先決定買唔買🤭
哇 責任重大 🤣
我都是睇麻你用後感 先決定買吾買 🙈
啱啱轉見人轉我又轉,裝左大轆仔就見你出呢條片~又學到野~~
😆 俾朋友毒咗！ 你裝咗咩大碌仔啊咁？
@@DarylSeanChan 裝左RIDEA.....早D 睇你條片就換NOVA 啦.....
用厭咗再換 🤣🤣
@@DarylSeanChan HAHAHAHHAA
好多11速Cassette 最重個波都係11牙, RB可能有14牙, 其實個Pulley大左真係冇乜用. Friction Facts有做到呢個測試, 後脾最好同最差嘅型號係慳到11W, 而家Fiction Facts俾Ceramic Speed買左, 以前啲third party測試睇唔返. 另一個大Pulley好處係個後脾可以容許更大飛輪嘅齒數差距. 我自己3D print左個Tension pulley, 放左個ceramic bearing, 改左個Shimano 11T改到15T放左喺架Scott MTB Scale 700, 係真係可以做到更大嘅齒差.
係，我覺得少遺憾friction facts 賣俾CS… 完全唔中立了！ 師兄有料，可以自己print 嘢 👍🏻👍🏻👍🏻
雖然講咁多最後慳得1~2.5w XD(心靈馬力應該唔止)
但真係好有心機，有理論有 data
心靈馬力可發揮無限潛能～ 🤣🤣🤣
多謝支持！🙏🏻🙏🏻
以前套SR11 Gen1得個紅蓋tension係用陶瓷軸承, 黑蓋guide pulley係用返普通金屬軸承。上年訂咗SR12, 見佢兩個都紅蓋心諗今次終於肯行晒陶瓷軸承, 雖然唔係啤呤但都好吖, 點知返嚟一拆原來係假狗, 兩個都係普通金屬軸承, 金寶你好嘢
🤣🤣🤣 唔拆黎睇好過
@@DarylSeanChan 其實我都係搵藉口換嘢啫😂 上年年中我都有睇過nova, 記得當日好似重有for機械件嘅SR12, 但後來唔知點解落咗架, 最後搵過晒得你片中用手扭得郁嗰隻同SLF有出, 由於扭得郁牌喺佢本土同香港都有唔少 人氣 嘅表現, 所以諗都唔諗直接揀SLF, 依家人唔踩得車都睇得
🤣🤣🤣 睇到真係吹漲嗰隻牌子 🤷🏻♂️🤷🏻♂️
有啲換碌仔為左騎帥不騎快
但watt數慳左又係件好事
雖然未必體感到
但睇完長知識了
多謝支持！🤩🤩
師兄，照你咁樣分析大導輪，我部單車用原裝Shimano bb，如果換cs bb，提升效能係咪都係冇乜幫助？
我覺得係比較細既分別 👍🏻
請問 現用R8000 原廠後導輪，飛輪11/34T，如換裝NOVA RIDE 大導輪時原來的鏈條要多加幾目數才能用? 謝謝!
這個最好你親身請教技師會更專業 👍🏻👍🏻
專業而中肯的分享👍🏼最欣賞是說出了空轉下的順唔係真正的順
多謝師兄支持！ 🤩🤩
好看就行啦
👍🏻👍🏻👍🏻
有問題想問 見到你波腳勾用DIRECT MOUNT HANGER 其實比起正常有咩好處?
輕少少同埋轉波感好似清脆利落啲～ 個人感受 🤭🤭
太好了，聽完你講之後，我決定用返原裝。
🤣 大獲
未睇先like
+1
多謝支持！
@@DarylSeanChan 成日聽大家講watt數，好似有啲虛無又帶點科學咁，期待你會出條片講下
查實Shimano, Campy & Sram 唔識制OSPW? 跟本波腳鈎受唔到咁大彈弓壓力！
三大廠商都有自己對套件既一套理論～ 可能為2W 而要犧牲既嘢（包括價錢）實在太大
我想問下係一個鐘節省 2.5 w 還是每一腳 節省2.5W 希望回覆謝謝
我的理解是....每腳，但是watt hour 不就是 2.5wh lolllll
我用著Ridea RD6C60(R8000)
師兄覺得怎樣？
@@DarylSeanChan 差別太小，沒什麽感覺到，我可以話自我感覺良好。。 哈哈🤣
咁就已經達到最大目的啦！🤣👍🏻
哈哈 結論還是心靈馬力最重要～
世事被你看透了～ 😆
支持
thank you!!
之前我都好犹豫要唔要换大轮仔,睇咗条片1道灵光打进我个脑～我决定咗唔换啦……
🤣🤣🤣 咁大鑊
哪家环法车队用佐大导轮？宾果？
World Tour 車隊斷斷續續的都有使用大導輪。 但是這些職業車隊的使用裝備我覺得我們凡人都不好拿來參考，畢竟他們都是贊助主導的運作。 比如說，Shimano贊助的車隊是有要求必須全套配件都是使用原廠零件，就算有功能上的區別也不能使用其他牌子的導輪/齒片/功率計等等～
淨係換個两個導輪做陶瓷有用嗎
我估性價比都係偏低的 😂
魚翅青菜，各有喜好，最緊要負擔到🫡
啱！ 其實原裝我都幾鍾意 🤣
其實換牙盤（大餅）除咗此齒比分別外 高級嘢有冇實質提升作用
通常貴啲輕啲，功能唔一定有顯著提升，甚至都有某啲情況高級部件比低級部件容易壞。 睇你想要咩、budget 幾多、平時做幾多防禦性維護～
輕左, 硬左
hi, 想問下w數係講梗w/kg定係總數
總數 🫣🫣
換大碌仔洗唔洗加長條車鏈？
要睇你本身條鏈夠唔夠長，如果夠就唔一定要換鏈，如果唔係就冇辦法～
11:40 nova ride 都係好似得2-3個咋喎💩
基本要求 😛😛
嗰度係mr. Velo?
yes! 佢幫我裝上去～
咁其實。。。會唔會。。。用原裝size 配返靚d 嘅轆仔係最好😅
好有可能ga！
Daryl 你好
海洋大大你好～
Honestly, all these OSPs are hyped up, and overpriced for very little performance gain. I rather spend it on a good BB which is more important.
Now the latest hype is waxed chains 😆😆 and honestly after using them, I’m convinced they’re worth the effort 👍🏻
7:33其實得長同短🤣
thank you!
7170 隻Nova 上唔到36T 🙁☹️😔
咁癲？ 係調教問題定係點啊？
@@DarylSeanChan 官網話34咋，雖然相信應該要上都無問題嘅 🤔
咁真係有啲kik
@@DarylSeanChan 7170就係貪36T 🥹
個人認為啲片高質過果個咩chrxx
平有平玩，貴有貴玩，當支持下後生仔
Daryl professional d 深入d, 觀眾群都唔同既
多謝支持！ 各有各觀眾群，佢有佢成功之道～ 👍🏻
睇佢啲片真係冇用
Daryl. You seem like a smart dude. But you have fallen for the marketing BS. Ceramic bearings are not more efficient than high quality SS ones.
I'm merely pointing out the claims that brands are putting out as well as the (limited) data they present. But at a (dubious) 2W gain, I agree it's pointless for mere mortals
@@DarylSeanChan The highest drag on bearings come from the weather/rain shield, then viscosity and amount of grease, then size and perfect roundness of bearings and lastly the quality/ hardness of the races.
Perfectly summing it up! 👍🏻👍🏻
XD
They are a complete waste of money. Literally useless in terms of performance gains.
