  1. I've built many wheels over the years and also swapped rims,
    so I figured it would be a snap to replace my old rim with a
    new Torelli Master (same ERD).

    As most of you know, the first step when lacing a wheel is
    to determine whether the rime is "right handed" or "left
    handed" (i.e., the offset of the spoke hole to the left of
    the valve hole).

    Well, it turns out that my new rim has the opposite
    "handedness" of my old rim. So I can't just transfer the
    spokes one at a time.

    Is there an easy way of swapping these rims while keeping
    the valve hole in the proper location AND keeping the spoke
    orientation at the hub the same?

    I am sure that I am missing the obvious, but what is wrong with "indexing" the rim over one spoke hole?

    Well, that would work, and I may end up doing that. But then
    the valve wouldn't be between two near parallel spokes. I
    could probably fit a pump onto the valve anyway, but it
    would look kind of dorky.

    I should mention that this is a rear wheel (naturally) with
    different spoke lengths right and left.

    Even if I completely disassemble the wheel, I'm not sure I
    could re-lace it "properly" without the spokes pulling
    differently on the hub flanges (not good!).

    Yes, you will have the "dorky" spoke arrangement by the valve hole, but unless you get a rim with the same handedness, you will not be able to attain the same alignment at the hub.

    Is the rim you are replacing also a Torelli?

    I have also done this type of swap many times, but never run into the diferent handedness of rims yet.
    I once replaced a SUN Rims CR18 with another SUN Rims CR18 and found out that the ERD wasn't the same. Now I always measure the ERDs, Spoke lengths, hub data, and then compare them before "blindly" moving ahead.

    If you want to do this, the thing to do is to remove all of
    the left side spokes from the hub and move them one hole
    over (either direction.)

    The issue of the spoke indentations in the hub flange is
    insignificant with the left side of a rear wheel, because
    those spokes are at low tension.

    Rotate the new rim one spoke and then tape them together.

    The obvious answer is to switch the rim around the other
    way. Yeah, the logo won't line up (be the same as the front:
    read it from the drive side) right, but it'll be MUCH easier
    than trying to re-lace the whole thing.

    I've had this problem a few times in my life. I don't like
    it, but I rationalize it because you can't see the logos
    when you're riding anyway...

    Nope, that doesn't work! Hold a rim horizontally on your lap
    with the valve hole opposite you. Let's say the spoke hole
    to the left of the valve hole is offset downward. Now flip
    the rim over. The spoke hole to the left of the valve hole
    will still be offset downward. Try it.

    Yikes! I'm having trouble picturing how to do that. Guess
    I'd start by lining the two rims up together, but offset by
    one hole. Then transfer the the right side spokes one at a
    time. Then remove each left side spoke from the hub and move
    them one hole over in the flange. Would the left side
    outbound spokes become inbound?

    What if I just kept the left side spokes in the hub, but
    re-routed where they go on the rim? Would that have the
    same effect?

    Thanks for the challenge!

    I'm glad to hear you say this. I had this same problem a
    while back and I decided that was probably the case, but
    didn't really like having the new spokes cross over the
    grooves from the old spokes.

    Several months later, the wheel is true and no catastrophic
    flange failiures yet..

    Art Harris

    So, if you want the valve hole between two near parallel spokes, why don't you just do this...
    Find on the old rim where the valve hole is between two parallel spokes and not the offset in the rim. Then, on the new rim rotate it such that the high/low offset matches the two parallel spokes. Tape the rims together. One and a time, unscrew and then screw the new spoke and nipple to the new rim making sure that the pattern for the offset matches so that you get the parallel spokes at the valve hole. Presto!

    Don't bother. Move the rim to a position where the holes
    in the old and new are parallel such that the stem is one
    space off from where it would be ideally and transfer
    spokes as usual. The reason for this is twofold. Don't
    respoke a hub in a different spoke pattern or you
    encourage flange failure. Don't take spokes out of the hub
    because that encourages spoke failures. Aesthetically its
    only a theoretical difference and makes no practical
    difference in use.

    You have the wrong impression of what the OP said. It has to
    do with which side the spoke offset is. You can't just flip
    the wheel around because you'll get a 180-degree rotation of
    the next spoke hole, which is itself a 180-mirror of the
    previous one, so you get a 360-rotation in effect.

    Regardless, the real way to handle wrong logos is to do the
    Rubik's Cube method... take off the sticker(s) and put them
    back on the way you want them 😉

    No, each spoke should be inserted the same way through the
    hub, and point in the same direction as before, just one
    hole over in the hub from where they were with the opposite-
    handed rim.

    No, the length wouldn't work out if you did that.

    The valve ends up in an unaesthetic small aperture instead
    of the usual wide point. Works but looks ugly.

    I'm with Art- that's a tough break.

    I'd live with the valve in the "wrong" spot as well.

    But would anyone consider drilling a second valve hole in

    Continuing OT: One of our in-house comics drilled an extra
    hole in a rim once and bolted in a presta valve to an
    otherwise Schrader tube. "Hey I don't need any adapters".

    I wouldn't either, but I assume it would work OK.

    Where's the limit? I suppose an extra 31 valve holes would
    likely have a significant effect on rim strength.
