  1. Hi all,
    Help!
    I'm preparing to build up a set of wheels and have a question
    regarding spoke lengths. More specifically--what are the proper
    lengths. The rims are 700c 36 hole Mavic Open Pros. The hubs are
    Shimano 105s. Using Spocalc, it tells me that the front spokes should
    be 294.8mm for a 3x pattern. The rear wheel needs 292.4 and 291.3mm
    spokes for the same pattern. Do I round up or down? Jobst's wheel
    bible states that spokes stretch. This would lead me to want to round
    down but should I? Wouldn't it be better to round up? Is a fraction of
    a millimeter that critical?
    Thanks!

    No, its not super critical and going to the closest whole number will
    work.

    Just round as usual. If .5 or higher, go up, else go down. Either way is
    not a big deal. The fraction of a MM is not going to make a difference.

  4. I round up always. .1 to .9, round up using DT spokes
