I wonder if "comfort" is related to general bodily flexibility? I ride nearly every day, for probably 9 - 10 months of the year I rarely use the same bike 2 days running. While my current 4 (quite restrained at the moment!) bikes are constant in b/b to saddle top measurement, other dimensions do differ. Back or shoulder discomfort is one of the few ailments from which I do not suffer.
I don't really understand the move saddle back for a more upright position thing. Presumably the front end would also need raising very considerably. Just tried moving further back on my winter bike while slotted into basic trainer (couldn't be bothered getting soaked on a Sunday!). Upright I'd need a 15" top tube to reach the bars and then my knees would not pass under the bars. Very high front end and swept back bars I assume?

Neither do I. Surely ones uprightness is a function of distance hand position to seat position, with one being more upright the shorter that distance. Assuming no change to hand position height.

As an instance of how tiny changes can affect comfort and power, I noticed on Friday that my proper bike didn’t feel totally right, very slightly lacking in power, and a teeny sensation of pull in the base of my back, which still hasn’t fully recovered from me overstretching it while shifting furniture about a month ago.

This morning I investigated and found that I’d left the seat about 5mm too high after holding the bike on the workstand, and that it had moved back c30mm, presumably because I had the wrong setting on the torque wrench when I fitted it a few weeks ago. So, I corrected both things.

Only had time for an hour whizz between downpours and lunch, but it seemed ‘back to its old self’. It might all be psychological, but I don’t think so.

You still weigh the same no matter what inclination you have

Keeping your arms off the bars ("no hands") throughout: when you lean forward what happens to the reading on the scales under the front wheels and the reading on the scales under the rear wheels?

I've just done the experiment.
