  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.

    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.

    Art Harris

    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..

    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.

    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!

    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.

    Is that a joke? Flipping the rim still leaves the

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

    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.
