Okay! The post was cut 55 mm. The bike went back onto the trainer. Apart from hiccups with the damned stickers falling off my hip, here are the results... Drum roll please...

Saddle set at 800 mm from 825 mm. Saddle setback moved to 98 mm from 90 mm. Cockpit lowered to 100 cm from 103.5 cm resulting in a drop of 6.5 cm (saddle-ground 106.5, bar-ground 100.0). Not certain my core can take much more than that right now. ;-)

I instantly felt the difference. Don't feel I'm rocking like the open seas. My foot is not straining on the down stroke (far more flat pedal stroke). My hands don't hurt as much (less forward weight). I know it isn't perfect but it's a lot better until the formal bike fit in 1-2 months.


Initially, installed the saddle @ 770 mm without changing the saddle setback



Plan: Raise saddle to 800 mm and saddle setback to ~ 98 mm. Checked knee-shaft with plumb bob and dead-center over crank @ 98 mm. Not sure about the extra 12 mm. I know taller riders sometimes have a little crank setback ~ 10 mm - something to ask the bike fitter about



Plan: Lower cockpit by 35 mm. Leave length as-is



The re-check (some of the dots kept falling off so I think there's some error here and made no additional changes)
