    DT-Swiss says to use 260mm spokes. I have 261mm spokes. Will the world end if I use these? I'm figuring not, but then again...

    It'll be fine. There should be enough threads to compensate for the extra mm.

    You should be fine, thats just 1mm, difference. Just make sure you check your tension when your done to make sure you can pull enough tension before you ride them.

    If what these guys are suggesting works, disregard this. but what you could do is clip off a mm of threads. if the threads are too short after, chase them. If not, use the spoke:clapping:

    It will be totally fine. You can be a couple of mm either side of the length needed and still get away with it.

    clipping them will probably mess up the threads enough that it will be difficult to thread the nipples on, but filing them would probably be ok.

    good point. ya, filing would be better, but probably unecessary.

    That's the rule of thumb. I can normally lace a front and rear wheel with the same box of spokes. 2mm each way is NOT a big deal. You will never know, and if your worried about your spokes getting to short, get longer nipples. It's all compensation.

    it can be an issue if the ERD if different from what DT is using. I built 4 wheels at the shop last week and only 1 had the correct ERD listed in various programs. This happens more often than not, I've noticed. Some rims have been as far as as 4mm which makes a substantial difference in spoke length.

    Always do your own measurements, then compare to what comes up on the site, no matter who calculator your using. If your building wheels you should have teh two yellow sticks for measuring ERD, and as far as hu measurements go, everyshop should have a caliper

    With what? :think:

    Threads are mechanically rolled onto spoke wire not cut with a die. There is no metal removed the threads are basically squeezed out of the spoke metal.


    OP, 1mm one way or the other isn't going to hurt anything. If my spoke calcs are within 2mm of each side of a dished wheel I use the same lenth for both sides.

    I think that everyone is ignoring the big picture here. We are talking 1mm extra length. Doesn't sound like much, but remember that we are talking about 32 times 1mm, which is 32 mm, which is 64 mm for two wheels. AND this is rotating weight. I would go for 259 and save the weight.

    This is what Ive seen/used

    http://www.philwood.com/Spoke Machine.htm

    Rolls the spokes into the wire as you cut it. I havent personally seen something specific to chase spoke threads, other than maybe getting a really really small die...which of coarse Cuts threads, not rolls threads.

    Cool, havent seen that before, So what do you do, cut your spokes with clippers, then roll the threads in with that? Just curious how this one works. Oh any idea what it costs?
