請問166CM是否上...(恕刪)

1. 52cm 有效水平上管. 以Giant TCR競賽幾何XS (+9cm stem 標準配備).
再視需要去"微調"座墊前後(+/- 0.5), stem length(+1?), handlebar角度.

Peloton的舒老闆身高167cm，騎上管535mm的車架，龍頭110mm

我身高175mm，跟他買同樣大小，同一款車架來騎，龍頭也是110mm

因為一個是腿短身長(手又長?), 且drop大概想<=3cm. (可能又是很喜歡setback大的人--"推"上坡)

一個是剛好相反, 且drop會蠻大的 (我也是如此, drop 一部7.2 cm, 另一為8.2).
(但 seat tube angle = ? seatpost offset 大? otherwise, setback 夠嗎?)

選車架跟你的手，腳，身體的比例有絕對的關係。對不起我打中文實在太慢，改打英文比較快。The C-T (center of bottom bracket, BB, to the top of the seat tube) is determined based on your leg length (or inseam). The T-T (top tube length, center of the head tube to the center of seat tube) is determined based on your arm length and upper torso length.

If you are 166 cm tall, then probably a seat tube length of 46 - 48 cm and a top tube tube length of 50 - 52 cm is an optimal choice. You better off stay in the middle range, instead of going to the extremes.

Different company has different frame size chart, some of them use the top tube length as frame size and the others use the seat tube length as their frame size. You need to look at their chart and the diagram to see exactly how they measure the frame size. For the above size, they may name "S" or "XS", but never "M". Sometimes, even for the same manufactruer, they doesn't name S or XS, instead, they name exactly the distance like 46 cm, 48 cm, .... You need to know what they meant, either they go by the seat tube length or the top tube length.

The bottom line is bring a tape measure (捲尺) to measure the frame size to see whether it will fit your size right, don't just trust the specifications.

You can fine tune the seat post height to match your leg length. Once you decide to go with 100 mm stem, you can adjust the saddle (seat) to match your arm length. The seat post has a greater adjustment range but the saddle has limited length to adjust. This is why a matched (correct) frame size is very important, particularly, the top tube length.

Sorry!....Actually, I don't think so.

龍頭長是比較後面才決定出來的!!
座墊高與座墊位置應先決定，座墊位置決定您的踩踏平台座艙空間....也就是座墊與踏板的相對位置得先確定出來，這牽涉到您的

1.腿長與大小腿比例
2.甚至您的卡鞋/鞋底板位置與高度
3.還有大小腿踩踏的曲度/夾角。

"座的位置"確定了之後，然後才依照您的柔軟度..上半身長....手臂長度...核心肌力...確定上管長與龍頭長度的組合(也就是一般通稱的reach)...

因為您的座墊位置牽涉到踩踏行為....所以座墊位置絕不是因為覺得不夠趴了...就任意往後娜...或者覺得太趴...就任意往前娜...

因此"不是"我今天先決定了龍頭要用10cm...才依照手臂長去調整座墊的位置。

非常認同 +1

從龍頭長度開始是本末倒置.

從龍頭長度設定座艙空間

這是我看到許多車店的做法

是不可行的!!!!!!!
