But a bigger frame also means a longer top tube,
Agreed a longer top tube will be as standard, i use a frame with a 56 top tube and a 120mm stem and have done for years, i know it fits me.
I could ride the next size down with a 55 top tube with a 110 stem, that would fit too but the seat tube would be too small and i would end up with spacers under the stem, sound familiar ?
and trying to solve a too-long top tube by sliding the seat forward isn't good advice at all.
Different saddles vary by that measurement, ever seen the length of a Fizik Arione, compared to a Flite ?
You dont sit in one position on a saddle so the position is important but not critical, we are talking about 15mm here, not 150mm
Any professional bike fitter would tell you this.
And would also be laughing all the way to the bank when they tell you you need a custom frame, which you won't.
Anyway we all seem to have our opinions and none is helping the OP, one mans good fit is anothers bad one, like i said further up, if he finds the fit good then thats all that matters, i wouldnt be happy but then again i very rarely am :wink:
