OP with an update.
Yesterday I came home with a Soma Fog Cutter frame. (in a box, carried by me on a bike for 10 miles from Universal, but that's another story). It's gorgeous.
Parts acquired thus far are a Selle Anatomica saddle, currently on my vintage Windsor, and a set of 105 11x3 integrated shifters, bars. Measuring up the Fog Cutter (which is gorgeous, did I mention) against my last list:
- Room for 38s plus fenders. 40 even. More even. Check.
- Speaking of fenders, full coverage with mud flaps. Still the plan
- While we're at it, eyelets for fenders and racks. Check.
- Fork mounts for a front rando rack I haven't purchased the fork yet. Probably going with the Steel Fog Cutter, which has mounts
- Three water bottle mounts No, just two.
- 700c wheels. I'm tall and there's plenty tire selection at 700c. Check.
- Generator hub lighting front and rear. Probably, though I'll keep looking at battery lights.
- Headlamp on the front rack Second guessing the front rack.
- Rechargeable 2nd headlight on the bars for high beam. Still the plan
- Generator tail light mounted on the rear fender. Still the plan
- Second battery powered tail-light on the seatpost Still the plan
- Gearing will be low low low. Did I mention low? I want to spin at 5 mph. Still the plan
- Coupled for travel Decided not.
- Cable shifters Yes
- Disc brakes Yes
- Shallow flared drop bars So-so on the bars I picked up.
- Tubeless ready, shallow v, alloy, black, no sticker rims Depends on how the budget sorts out.
- Wahoo Element GPS Not in the budget.
- Handlebar bag Still the plan
- Under-seat bag Still the plan
- Chain hanger on the seatstay. Because I like them. Nope
- Pump peg and frame pump, if such things still exist. Nope
- Externally routed cables with cable stops and maximum exposed inner wire Check
Things to consider- Hydraulic or mechanical discs. Depends on coupler technology. Cable actuated hydro is the plan
- Paint matching custom metal fenders or replacable off-the-shelf fenders Soma has matching fenders. Like black though. TBD
- Frame pump mounting location. Hmmm
- Frame and fork material. Tending toward steel/carbon. Steel is real
