這陣子在研究fitting, 同時對於車把手產生了好奇
各品牌的傳統把與小彎把的 reach 與 drop 竟然可以差這麼多
這邊拿 3T 與 Zipp 當做例子
Zipp SL-70
R:70mm 與名稱標示相符, 算是有名的短?
D:128mm
3T SUPERLEGGERA
R:104mm !! 好長...
D:148mm !! 好趴...
3T SUPERERGO
R:77mm 感覺中庸
D:119mm 感覺中庸
這邊有幾個觀念想要請教大家:
1. 把手的 Reach 與 Drop 選擇,影響 fitting 的程度會比龍頭長度來的嚴重嗎?
看了好幾家大廠的傳統把,Reach 幾乎都85mm起跳...
2. 假設今天有兩種選擇 Reach 與 龍頭長度搭配
Reach 104mm + 龍頭 90mm = 194mm
Reach 70mm + 龍頭120mm = 190mm
這兩種組合對於上半身的延伸來說,算是「等效」的嗎?可以這樣去換算嗎?
3. Drop 只是單純影響到抓下把位的「手感」與「夠不夠趴」嗎?
