I am linking some videos below of the progression of my fit adjustments. I welcome any constructive criticisms regarding potential improvements. Comments that I should lose weight or buy a different bike will be understood, but not necessarily acted on.
Here was the starting point. The frame size is Small, which was the size recommended by the fit guide, but the cockpit felt cramped.
I switched to a longer stem. I felt I could hold a lower position, so I turned the stem for a negative angle. I received comments that I should switch to shorter cranks in order to open my hip angle.
Changing the crank length required changing the bottom bracket and the chain rings. The original cranks were 170 mm. The new ones are 155 mm. Reducing the crank length 15 mm led to raising the seat 15 mm. I inserted shims to angle the aerobars upward to stop the sensation that I was at risk of sliding off the front of the bike. I also inserted some spacers below the aerobars to reduce the amount I had to bend my neck to see forward. There didn't seem to be any reason to raise the base bars, so I left the stem with a negative angle.
