  1. I saw a badly abused lugged steel road bike today that, at first
    glance, looks like it meets all my requirements for a new frame.

    The frame looks like it is sufficiently small and the threaded headset
    currently has the handlebars up good and high, which, since this is
    intended to be a touring/daily use road bike is important.

    The probably 27" wheels have enough clearance for full metal fenders
    and yet still have lots of clearance between wheel and seat-tube.
    I've got 700c wheels. Those are smaller than 27", right?

    Completely unknown brand name (not even recognizable as one of the
    known Chinese brands). The bike appears to have been spare-parted a
    few times because although there are places for derailleurs (missing)
    I find it hard to believe that a random Chinese road bike would have
    ever started out with a triple.

    Horizontal dropouts.

    I'm going to try to take my mechanic by to see it tomorrow around
    lunchtime and ask his opinion but figure before I do that to start
    here. By the time it becomes lunchtime tomorrow and the two of us are
    off work from race stuff I'll probably have already gotten at least
    one answer on here to let me know whether it is worth wasting his time
    for us to go by together.

    I'm worrying about the bottom bracket and about the wheel spacing. Is
    there any way short of measuring tapes to guess if it'll fit?

    Yes. ISO 622 (700C) vs ISO 630 (27"😉, where those numbers are the
    effective rim diameters in mm.

    I'm not up on the ins and outs of China's domestic-market road bikes,
    but the quick and dirty guess is that if it takes 27" wheels, it has an ISO bottom bracket, which is good news.

    The wheel spacing is moot. There's a 99.9% chance the front uses the standard wheel spacing, and whatever the rear (and, for that matter, the front) actually is, steel frames can easily be cold-set to whatever is necessary.

    It's a copy. Of SOMETHING. No idea what it is a copy of but it
    certainly is a copy. Wouldn't have bothered making it if it weren't a
    copy. Really no point.

    The bike frame I'm replacing is very clearly a racing frame. Except
    for having been made out of about 5 pounds of aluminum.

    My favorites are the oversized aluminum frame lookalike tubes on bikes
    that are actually made out of steel.

    One brand has a almost not [censored] aluminum mountain bike frame with very
    definitely [censored] components which looks really really nice due to the
    carbon fiber paint job. I had a riding buddy who owned one of them
    for a while and he absolutely loved screwing with people's brains
    because they'd pick it up expecting it to be a lightweight dream
    machine and end up finding themselves attempting to lift a 35 pound
    bike with two fingers.

    I've also seen fancy aerodynamic track time trial bike copies (twice)
    that were actually steel and achieved the fancy shape by way of
    (heavy) plastic covers (like that stuff little kids' playground
    equipment is made out of). I was especially impressed by the wood
    grain on the one 'track' bike.

    One of my friends has an abso-bloody-lutely perfectly fits every
    single criteria I want touring frame ... complete with eyelets on the
    front fork. However, it has two major problems.

    1) It belongs to him
    2) It's Hi-Ten steel and is _really_ heavy. (I suspect concrete may
    have been poured inside the tubes just in case it needed to be a
    little heavier.)

    Yay!
