Thanks. Here is the data:
Specialized Myka Sport ... 52.5cm top tube, STA 74 degrees
Specialized Jett Comp ... 53cm top tube, STA 73 degrees
Jamis Trail X2 ... 52.1cm top tube, STA 74 degrees
49cm Top tube ... a Kona Kula, STA 73 degrees
Motobecane ... 52cm top tubes, STA 73 degrees
So, only one degree difference. Does it matter?
