  1. I was doing natural trials on some rocks today and bent a spoke.
    Here's a picture.

    What should I do about it? Should I just try to tighten it or put
    another one in?
    The eyelet in the rim wobbles as well.

  2. You should be okay to ride on that for a while, but I'd take it down to
    the LBS at the weekend if I were you. Ask them to replace it.
    I wouldn't have a go myself unless you know what you are doing. Wheel
    builds are a dark magic.

    I'll probably take it there, watch them replace it and do it myself the
    next time. It might be a dark magic, but it's the kind of magic that I
    simply have to learn.

  4. You have to pay attantion, if you tight it, that you tight both spokes
    around aswell. In that way the rim doesn't .....ah man i don't know the
    word

  5. what i would do:

    remove wheel
    remove tire and rim strip
    remove nipple on bent spoke
    straiten spoke by bending slowly the other direction
    look for stress lines (if present buy a new spoke)
    put a small amount of light oil on the end of the spoke
    put the nipple back on the spoke and tighten to slightly less tight
    than sourounding spokes
    check for wheel trueness and roundness
    tighten apropriate spokes
    check for dead sounding spokes (pluck each one and listen to the tune)
    put everything back together

    its simpler than it sounds and if you arnt using a break your wheel can
    be a bit out of true without any problems.

    i would recomend buying some spare spokes and have them handy for the
    next time this hapens they are cheep and dont take much room to store.

    Working with wheels isn't magic. You should be able to remove that
    spoke and replace it with one of the appropriate length. See
    information on sheldonbrown.com; it's not that hard.

    I wouldn't bother trying to repair that particular spoke; it looks
    pretty tweaked.

  7. I think I'm gonna go to the LBS tomorrow and buy some spokes. How should
    I choose them? What measurements should I give to the mechanic? I tried
    the 'spoke calculator' (http://www.unicycle.uk.com/SpokeCalc.asp), but
    it doesn't have my rim.

    Could someone help me out? I have a QU-AX splined hub with the stock
    24" rim(BX-38).

    Take the spoke out and measure it, that's your best bet.

    keep your spokes tight and save your rim! spoke tention is what keeps a
    wheel strong. checking and tightening your spokes is a very easy way to
    keep your wheel in good shape

  12. it should be fine if you just bend it back. When they are made they heat
    treat the steel then make the bend that is by the hub.

    Yes...which is why nearly all spoke failures happen at the elbow.

    I don't think that spoke is likely to fail at the point where it's
    bent, but a bent spoke will not hold tension properly.
