Spoke hole size in hubs

Discussion in 'Cycling Equipment' started by [email protected], Dec 18, 2004.

  1. Hi all
    I building a wheel w/ Sapim 2.0 /1.8 spokes & an XT M752 rear hub.
    Shimano lists the size of the spoke holes is 2.6mm, which I have
    confirmed w/ a digital caliber. When I insert a spoke, it rattles
    around quite a bit. I have been unable to find this problem addressed
    in "The Book".
    Two questions:
    1. Am I just missing this subject in "The Book"? If so, what
    page(s)?
    2. What do rbt wheel builders do about this situation. Do you use DT
    Spoke washers? However due to the fact that Sapim does not make the "J"
    end of their spokes as long as DT does, won't the spokes leaving the
    holes be forced into too oblique of an angle, making it difficult, if
    not impossible to flatten them against the hub?
    Best Wishes, for the Holidays, John

    I say, use the DT spoke washers, and ensure the spoke head is seated in the hub
    after building with a spoke head punch setter. After a wee bit of tension is on
    the wheel, a light tap with this tool will seat the spoke head with the spoke
    washer.

  3. Thanks Peter for the advice.
    That's what I'm going to do. Next time I'll use a hub w/ 2.3mm holes.
    Happy Holidays, John
