so what do you think about now?it seems that if a 55,4cm top tube frame with a 10cm stem is ideal for me,then a 57,5cm frame with an 8cm stem will do the job,but a little more twitchy and nervous steering due to the shorter length of the stem.am i right?or is it completely wrong that assumption?

i apologise for my english but its not my native language!
