剛剛做出來還熱熱低...雷雕技術真是精益求精；據說能夠細到刻一幅山水畫，珍架係一流台灣技術!!

跟搖滾人的碟盤好像
難道都是系出同門 台灣製造精品？
會長大人出品的 應該會有價格優勢！？

i would pay extra for the rock rotor just to not have to look at that silly logo

產品贊不贊，是消費者來決定。

碟盤都是洞, 跟煞車皮的接觸面減少了許多, 這樣子煞車效果不是會打折嗎?

yes. there is going to be a decrease in braking power. They will also make the brake modulate inconsistently. I have been switching back and forth from hope, tryall, and rockman rotors, and the difference is noticeable.

You always have to sacrifice one thing for another. I suppose this is the case with wanting a lighter rotor.

是的, 煞車效果將會有減少. 也會使煞車皮與碟盤接觸不穩定. 我曾經來回使用 hope, tryall, 及rockman 的碟盤, 這些不同碟盤的煞車效果的差異性是很明顯的.

你總是需要犧牲一些才能得到另一些. 我想這就是想要一個更輕碟盤的代價.

使用HS-33時, 通常將輪框磨成粗糙的表面會使煞車增強, 但我曾經將碟盤磨粗的結果, 煞車效果反而更差, 這是為什麼呢?

the polyurethane used for hs-33 trials pads are much softer than disc brake pads. This allows the pad to dig into the rough surface, creating more friction. The piston also acts as a fulcrum for the pad. This means that when the pad is in contact with the rim, and there is force applied on the wheel, the pad will rotate slightly on the piston, giving you a tiny bit more torque.

I'm not really sure why disc brakes dont work with really cut out rotors. they just don't. maybe arrowsun can pitch in some physics lessons

哇!這可能要問神明囉!!可以請經常問神明價格的阿哲代勞...哈哈...開玩笑低...別介意哈...
碟煞車圈煞的比較,坊間比比皆是...網路上不難找；不過碟煞和車圈煞的煞車皮材質差很多，也許是原因之一...

HS-33的PU煞車皮材質比碟煞的煞車皮硬度軟很多. 這樣使得煞車皮得以咬進粗糙的表面造成更多摩擦力. HS-33煞車油缸的活塞也成為煞車皮的一個支點. 意思就是當煞車皮與輪圈接觸時, 煞車皮可以在活塞上輕微的轉動, 增加稍微的扭力.

我並不能確定為什麼碟煞在磨粗的碟片上沒有效果. 反正就是效果不佳. 也許小江可以來開一些課講物理.

我的小車後輪一向都用HS-33, 當我試著用碟煞的時候, 我覺得碟煞的手感比HS-33軟一些, 這一點是還好, 但是在踢踏板放煞車要跳高跳遠的時候, 這個軟的手感讓我有爆發力減少的感覺, 會這樣嗎?

i dont think i've ever felt a properly setup hope brake that is softer than hs-33. i am guessing the pads were not bedded in properly, and the brake mounts were not faced?

哈哈哈~~神愛世人~~所以信阿哲得永生~~

中譯:

我不認為我覺得組裝良好的 hope 碟煞的效果會比 hs-33 軟. 我猜可能是碟片還沒有磨合, 及安裝碟煞時沒有洗面?(註: 洗面是指車架表面接點的研磨).

神明不管這種事的


每天拜拜就能跳上170嗎?

主要跟碟盤的外緣形狀比較有差

我用過一片76g的碟盤

那片智偉也有用過



由於這片碟盤的外緣過於不規則，

碟煞咬合的時候等於是碟盤"切過"來令片

另外是洞開的太大，接觸面積過少

這些原因造成需要較長的磨合期

以及在磨合完畢之後剎車效果不如預期。

個人覺得越輕量的碟盤，洞就必須開得越多，相對的摩擦的面積也跟著減少
因此煞車力通常都會減弱

還有鋼性也會減弱，會有輪子軟軟的錯覺

假使不在意重量的話，很oldschool的那種最好用

最大的缺點就是重量，還有似乎和亨國搭配都會有共震的問題，其它的碟煞就不知到了
