I ride road and CX - and after a terrible year in cx (my offroad skills blow) - I have decided to get a mtn bike and spend a lot of time on it this year.
My top tube is generally a 560mm (+/-5) and stem is 100mm
I have been looking at a lot of mtn frames lately and they are all over the place. Ive riddena few with different tt lengths and cant tell much of a difference on any kind of demo rides. one bike might have a longer stem or a different seat angle etc.
What is the "standard" to look for when converting your road TT to mtn? I'm guessing I would be looking for something in the 608-618mm range?
