2x2, frame options?
Thanks for any advice on the following. i know this is a bit open ended.
I built up a mountain bike frame with horizontal dropouts to be a 2x2 "singlespeed" commuter. two chainrings, two cogs spaced on a shimano freewheel hub. one chain tug. one chain length because total gear teeth are the same (42x16, 36x22). 20 second swap: stop, loosen wheel, move chain inboard or outboard, tighten wheel, and ride. i need a cruising gear, and a climbing gear for a very steep 1 mile climb where i live.
I'm looking to do the same in building from a road frame, so i'm looking for a frame suitable for typical dished road wheels that can accept a cassette, but also has horizontal dropouts (130mm) . I'm pretty easy to fit.
could go custom and high-end or recycle an old frame and build from there.
steel, ti, Al; i don't care that much.
any suggestions on frames? i'm open to suggestions.
here's a pic of my current 2x2 built from a sycip steel mt bike frame:

are there no frames with 130mm spaced horizontal dropouts in a slightly relaxed geometry, with a water bottle mount? bianchi pista, jamis sputnik, etc. are all 120mm dropouts, right? do i need to go custom?
0ld roadies will do that for you.

Surly has a steel offering or two with 132.5 mm rear spacing. The idea is you can use a road or MTB hub and either one will work fine.
