Are Oversized Pulley Wheels More Efficient? | 大導輪真的是更高效率？ 解答一切疑問！

[@五千乘之勁宋]

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。

[@DarylSeanChan]

可惜我鈔能力不足，還沒堆成塔就只留一盤散沙 🤣🤣🤣🫣🫣

[@theodoresiu266]

加下加下加到20 就正啦

[@kuanhau4323]

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!

[@DarylSeanChan]

Thanks dude, that's a really interesting idea! Intuitively I think BB would yield bigger differences too but who knows!

[@kuanhau4323]

@@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.

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

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.

[@DarylSeanChan]

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 👍🏻👍🏻👍🏻

[@creative907]

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!

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～
