WOW, that's a HUGE change. Old geomentry I HAD to ride a 44 because the standover hight was to high for anything else, but for me the top tube was way to short and I felt to compressed on it. Now I might be able to comfortably ride a 44. However, I found a men's bike at the time I was looking that fits me great.
My road bike is a Felt F5 48cm, it's standover height is 681 and it's top tube length is 510. I love the bike.
