近日來一直有想換輪組的打算,但了解過去才能夠繼續前進,因此先在網路上蒐集了目前挑戰者號輪組的相關資訊,看看它是在哪個等級,才不會花了冤枉錢。

"First-rate build and good ride quality"
Ritchey have always made good, dependable products and these wheels follow that tradition. The rims, spokes and hubs are all basic but very well made.
The build is first-rate, with tight spoke tension and exceptional straightness. The rear wheel uses Ritchey's OCR (Off Centre Rim) system, where the spokes are positioned off-centre in the rim to reduce dishing. This results in a wheel that has a more even than usual spoke tension from the drive side to the non-drive side, and we know from experience that it will take a little more abuse than usual to knock it out of true. The ride quality has a good balance of quick acceleration and high-speed stability. These are impressively stiff, if a little harsh over the bumps.
Ritchey 總是製造良好可靠的產品,而這些輪子也符合這傳統。輪圈、幅條、花鼓皆為基本款,但製造良好。
這組輪子為初階輪組,幅條筆直且張力緊實,後輪使用了Ritchey的OCR System(Off Center Rim),幅條的位置不在輪圈的中心上,可減少碟型對稱(註1),這結果會使幅條側的鋼斯拉力由大盤側移至非大盤側,且依據經驗這樣的設計會使輪心較一般設計不易離開中心。這組輪組在快速加速及維持高速穩定上有著良好的平衡,且當碰到粗糙顛簸的路面時,這組輪組的鋼性令人印象深刻。
資料查完了,看來這組輪子鋼性很不錯,還蠻適合體重很重的我,騎了2年,只踩斷過一次鋼絲,我練習時踩踏的迴轉速都保持在90rpm以上,不重踩讓目前偏擺情況尚可接受,但有空還是應該要去校正,狀況應該會更好,重量1800g與Mavic入門級的輪組Aksium Race的1855g算是差不多,在換了馬牌的GP3000外胎與Ulterga 12-27飛輪後,整組輪組拿起來感覺較TCR Alliance 所搭配的Mavic Aksium Race要輕一些,但荖濃溪鐵人賽前拆開花鼓整理發現是滾珠的花鼓,不及Aksium Race培林花鼓來的順暢許多,但滾珠花鼓保養倒蠻容易的,拆開花鼓後把鐵珠與花鼓徹底清潔,換上新的黃油,感覺較原來順暢許多,或許換不同材質的鐵珠與黃油會有更好的表現(會嗎?)。查了一下Mavic 的萬元級的輪組,Ksyrium Elite(1690g)及Ksyrium Equipe(1770g),重量與這組都沒有差許多,看了靖恆的小墨配的輪組RS-10(1840g),等級尚不及Aksium Race,秋賢的輪子是黑牌的碳纖板輪,平路騎起來倒蠻快的,國璋的Khamsin G3,棘輪的聲音大的讓人受不了,但踩起來一點不拖泥帶水,有種力量100%傳達到的感覺,看來如果要換輪組,可能還是也是得採一次到位的戰術(Mavic R-sys、Mavic SL、Fulcrum Racing Zero),免得小朋友多出走了,在這之前多練練車才是真的,這組Ritchey Aero Road如此堅固耐用,拿來練車真是恰到好處。
註1:dishing碟型對稱:所謂的Dishing碟型對稱,是指車輪左右兩側從花轂軸到輪圈的「凸起」程度,如果我們把車輪橫放,那麼這整個形狀看起來就像是個「碟子」,一個車輪左邊右邊各有一個「碟型」,這兩個碟型必需對稱。這個工作聽說有的自行車廠叫它作「正心」,也就是確定輪圈的位置確實垂直在花轂軸的正中心。(資料來源:ohmylife的手編輪組實驗室)
