This is my ideal setup :
Top of Handlebars to Floor - 95cm
Bottom Bracket to Top of Saddle - 75cm
Saddle Nose to Handlebars - 49cm
Saddle behind Bottom Bracket - 58mm.

Is that before or after you've re-tensioned over a period of years? - a B17 can easily lengthen by 19mm when properly, and not excessively - tensioned.
How long is your saddle - from sit-bone depression to nose? - do you only ever use one type/make of saddle?
Which point of the saddle is 58mm behind bottom bracket (presumably centre-line of spindle)?
What do you refer to as "top" of the saddle?
Have you not measured the horizontal distance between sit-bone- depression centre and front pedal-spindle centre-line with cranks horizontal?
My saddles are Brooks Pro and have never been tensioned. Tell a lie ........ I bought the Brooks spanner some years ago and had a tweak of the older one. I turned the nut less then a quarter of a turn perhaps. So long ago, I forget.
My saddles are level, so the top of the saddle is the same level front to back. Straight edge along them nose to tail.
I measured the saddle position fore and aft from the very front of the saddle nose to the centre-line of the 'bars at the stem.
Just measured sit-bone indentations to saddle nose as 230mm but it's rather vague as there isn't much of an indentation because these saddles are rock hard. The one on Mercian has done in excess of 40,000miles but the one on Moulton is approaching only 4,000miles. Mercian's saddle is indented more than Moulton's of course, but neither of them is indented enough to measure accurately.
No it's not meaningless.reohn2 wrote:The floor to handlebars measurement is meaningless,a more meangful measurement is from saddle height,ie; once the saddle is in the correct position in relation to the BB,the handlebars are set in relation to that.
How do you know your 'bar height?
Buy a new bike, fit a new saddle like on the other bike, and adjust it as per any measurements you take from the other bike.
Similarly, adjust the handlebars to the correct height. Get the 'bars right, then get the saddle right. That's the way I did it, and it worked ........... that's from when I had a Raleigh Clubman transferring to Mercian, and now transferring to Moulton.
