A-D: Nice classic bike. I see no triple crank, and also, is it me, or is the inner ring not a 42, but larger, closer to half-step gearing? Just curious. If you don't need the lows on the hills, especially if you climb while standing, great. Me, if a long hill, I need a bailout low to spin if I run out of gas climbing, I can't push hard while sitting, hurts my knees.

Glad you can do low drop bars. Me, even in my prime, too low for me, I went with bullhorn bars tilted up at about 30 degrees maybe, perfect height and hand position for me most of the time, and clip-on aeros for when I needed aero.

On my current flat-bar bike, I considered bullhorns, but realized that is a lot more narrow than I like now, so went with bar-ends on the flat bars, about 15 cm wider.
