    Incurable hop on new wheelset

    I just (almost) finished building up a 24x0 wheel (Sun Venus rim w/ Wheelsmith DB14 spokes) and am having a problem. I tensioned it evenly and then performed a few tiny adjustments to get it round. However, I'm having a vertical hop right near the weld opposite the valve hole. I've tried bumping up the tension there but it's not having much effect. Any advice?

    I am pretty sure that all wheels have a slight hop near the rim weld. It is nothing to worry about.

    The wheel is a system, and just tensioning one spot may not be enough. Try detensioning the rest of the wheel slightly. Go to the center of the hop and then out about 2-3 spokes on each side. Back off tension on the remaining spokes about 1/8 turn. Then go back and try round again. If the hop is only right at the weld (1" or less in length) then I would consider that a defect on a decent quality wheel, not a "hop."

    Right near the weld = nothing you can do about it.
