    Flow control: the outport is designed to only let the serious outflow
    out when the frame fills to excessive levels. We do this with "land
    architecture" and engineering terrain drainage systems all the time.
    You want to maintain a certain level so the selected plant life can
    properly grow and flourish.

    It make a pleasant flute-like sound at speed. Water changes the pitch.

    In that second photo, the hole in the chainstay may be the bridge. You
    drill a hole through both walls of both chainstays and then insert a
    tube. I've never seen an example of this type of construction, but Tim
    Paterek describes it in his framebuilding manual (p. 3-16).

    Dear Gary,

    You may be right, but the hole would put the bridge awfully close to
    the bottom bracket.

    I'm not sure if the two uncaptioned pictures are of the same frame or
    of different frames.

    If they're the same frame (?), the first picture shows a chainstay
    bridge in place and much further from the bottom bracket than the hole
    in the chainstay in the second picture.

    Whatever's going on, it's a good example of how a little explanation
    and some better pictures would clear things up.

    Cheers,

    Carl Fogel

    I think that's the seatstay bridge in the first photo, not the chainstay
    bridge. It doesn't look like it's drilled for a brake, so maybe this is a
    track bike -- in which case it wouldn't surprise me if the bike had very
    short chainstays (and a bridge very close to the bottom bracket).

    Dear D,

    Well, at least it explains that Gary's right and that I was wrong
    about the bridge--it's a seatstay bridge:

    I'm not sure what the auction shows about the mystery hole, which is

    http://i24.ebayimg.com/08/i/000/cc/df/bc7c_12.JPG

    Maybe a very curved chainstay bridge went in through the hole?

    http://i6.ebayimg.com/08/i/000/cc/df/a6fe_12.JPG

    I can't tell what's happening right behind the bottom bracket.

    Yes, explanations there, too -- it does specify an open CS bridge and
    open tube ends -- most builders either dome the tube ends or fill them
    with spelter, but it's not really necessary if the joints are done well,
    and it does save fractions of an ounce of filler.

    See the bit of blue inside the hole (bc7c_12.JPG)? That's the bridge --
    just imagine driving a straight piece of tubing through both chainstays,
    cutting the ends flush with the outside walls of the chainstays, and then
    brazing it in place. It's like a tunnel through the chainstays. Because
    of the presence of the tube, the chainstays themselves are just as much
    sealed as on an ordinary frame. (The seatstays are a different matter,
    and are probably open at both ends.)

    Dear Gary,

    You may be right. I can't tell if that's the inside of a piece of
    bridge tubing or just the far wall of the chainstay:

    http://i24.ebayimg.com/08/i/000/cc/df/bc7c_12.JPG

    As for the curving, it looks to me as if the bridge piece in the
    chainstay (if there is one--that's how unsure I am) has to be a curved
    shape to end up so far forward from the hole (if it's going through
    the hole):

    http://i12.ebayimg.com/02/i/000/cc/df/b112_12.JPG

    But now I wonder if maybe the camera angle is deceiving me.

    Frustratingly, we could tell for sure in a second or two if we had the
    actual bike. If I had to bet at this point, I'd bet on your
    explanation.

    Cheers,

    Carl Fogel

    Dear Josh,

    Aha! Lucky for me that someone read the text--I got sidetracked at the
    pictures. It does indeed say open CS bridge, so Gary's right and my
    doubts were just plain wrong.

    Never mind--you're right and I was wrong to doubt you.

    I could have told for sure in a second without any frustration at all
    if I'd read the text of the auction below the pictures.

    Luckily, Josh has an adult attention span and pointed this out.

    Cheers,

    In that second photo, the hole in the chainstay may be the bridge. You
    drill a hole through both walls of both chainstays and then insert a
    tube. I've never seen an example of this type of construction, but Tim
    Paterek describes it in his framebuilding manual (p. 3-16).

    Cog Magazine centerfold this month for the most extreme example ever!
