OK. So for all of you with vast knowledge of frame building, engineering, and the requisite mathematics I have a question to ask.

Say that one had a funnybike, an older version with the 24" front wheel and 700c rear. What kind of geometry changes would occur if you replaced the front fork and wheel with a 650? This is assuming that the 24" is the more common small wheel which measures 520mm and that the 650 is the more common 650c which measures 571mm, for an overall difference of 5.1cm which would raise the front end by 2.55cm. Would the resulting change in geometry severely alter the handling of the bicycle?
