我的車是ROUBAIX PRO最小的尺寸（曲柄長165mm），
原先我也以為女生用C-C 380mm的把手比較剛好，
所以牽車時就直接請老闆換掉，但騎起來就是覺得整個肩膀是向內縮的。
牽車後幾個月去舒米那裡報到，發現原來我還是要用C-C 400mm的把手，
所以，不是女生就一定要用比400mm小的把手，仍要看車手的身材而定。

好奇請問你的肩寬是多少?

不過你可以騎Roubuaix Pro代表你的跨高比我高
因為Roubuaix是水平上管(stand over height兩台差約2.2cm)

短上管的700C車架不只會有toe overlap的問題，頭管角度太小影響操控的問題也不小。

這些都是縮短上管但要維持前輪軸距的副作用。

建議身型嬌小的車友們還是要以650C的車架為優先考量。

Cervelo RS針對XS尺寸車架搭配650c輪子的解釋很清楚：
* Eliminated toe-overlap by using 650c wheels for the XS size. Toe overlap is not a problem for experienced riders, but can be intimidating for some. Using 650c wheels in the XS size is the only way to solve this problem without compromising the weight distribution and thus handling. Every solution that eliminates toe-overlap but keeps 700c wheels suffers in handling.

Explanation for the 650c wheel solution on the XS size: A smaller frame means the front wheel moves closer to the rider’s feet, causing toe-overlap. While inconvenient at walking pace, this issue disappears at normal riding speeds as the actual steering angles become very small. There are four ways to deal with this:

1) Accept toe overlap, after all it is not a problem if the rider is aware of it at low speeds, and it does not occur at higher speeds.

2) Use 650c wheels, which allow us to move the wheel closer but thanks to its smaller diameter it will never touch the rider’s toes.

3) Leave the front wheel far out front, but then the weight distribution will not be balanced.

4) Mess up the rider position by moving the rider forward instead of the wheel and handlebar rearward. But a changed position will not be comfortable, and the weight distribution will again be compromised.

Compromised weight distribution and therefore handling make options 3 and 4 unacceptable, leaving options 1 & 2. If you are a racer and neutral support is important, or you want commonality of parts with other 700c bikes, then option 1 is the best solution. We offer this on most of our road bikes. Option 2 is a great solution if you are concerned about toe overlap, never need neutral support and carry a spare for yourself (since your riding partners will likely have only 700c spare tubes, although even those work in a pinch, just fold them in – no problem).
