The seatpost is roughly 4 inches above the top tube (not a v exact as have no spirit level at home). I'm fairly petite so I reckon short reach narrow bars would help no matter which bike I was on.

I guess in an ideal world, I'd like a setup with a very compact frame so I could have my saddle a long way above the top tube but with my height, I reckon the dimensions would be that of a kids bike!

Do you guys reckon a 70 or 80mm stem would be OK in terms of handling? I know a longer stem would obviously be better but in a world of trade-offs, are those lengths reasonable?
