A question or two, if anybody knows more about this.
The pbmcoaching diagram makes sense to me, but I don't quite get the measurement of the saddle height (length "A") on the parktool diagram. It's measuring from the bottom bracket to some vague point behind the saddle? That must not be right. What exactly is the reference point, then?
The other links (umich, bikefitadvisor) don't lead to diagrams that I can find. Can anybody point to any other suggested standard measurement templates?
Background: I'm trying to match the fit on two road bikes, but they have different seat tube angles, so I need a standard reference point on the saddle to aim for. I've seen people suggest something like 60% of the length from the nose to the back of the saddle. I like the pbmcoaching suggestion of measuring to the 80 mm width.
