急..公路車車架尺寸?

這是我的個人資料:

Trunk 67 cm
Forearm 34 cm
Arm 61 cm
Thigh 57.5 cm
Lower Leg 51 cm
Sternal Notch 140 cm
Total Body Height 168 cm

這是我做出來的結果:

The Competitive Fit The Eddy Fit The French Fit
Seat tube range c-c 48.9 - 49.4 50.1 - 50.6 51.8 - 52.3
Seat tube range c-t 50.4 - 50.9 51.6 - 52.1 53.3 - 53.8

Stem Length 10.9 - 11.5 9.8 - 10.4 10.0 - 10.6
BB-Saddle Position 64.4 - 66.4 63.6 - 65.6 61.9 - 63.9
Saddle-Handlebar 51.7 - 52.3 52.5 - 53.1 54.2 - 54.8
Saddle Setback 3.2 - 3.6 4.4 - 4.8 3.9 - 4.3

我的問題是我的身高才168cm， 跨下75.5cm，49cm的車架會不會太大，
爬了很多文發現跟我差不多身材好像都騎46cm的車架居多，
不知各位前輩有何建議?謝謝!!
