    Wheel Builder Spoke/Nipple Questions

    Gonna keep this generic because it relates to all wheels (my specific happens to be for my roadbike)

    Had a nipple break, also bending the spoke.

    After taking things apart I find that the spokes barely come to the bottom of the screw driver slot, some are flush, others are below.

    Should I replace this an all the spokes with new spokes that are 2mm longer? The extra 2mm would put the end of the spoke close to the end of the nipple. From my understanding that is a more ideal situation than to short, especially with alloy nipples.

    For reference my spokes are someplace between the left and middle of the below example.

    Where did the nipple break?

    Strength wise, somewhere between middle and right is your strongest. But remember, the pictures you are showing are with the nipple screwed in to the same point where you have about 2 turns left.

    It broke basically at the end of the spoke, which fell short of the screwdriver slot.

    I estimate with the current spoke/nipple combo, there is 4mm before the spoke would bottom out.

    Flush with the bottom of the slot is the optimum length.

    Yep^^. Middle picture is ideal. I had a Specialized that came with straight gauge 2mm spokes and aluminum nipples. I kept breaking nipples. I realized all the spokes were too short like the left pic. Rebuilt the wheels with 2mm longer double butted spokes and brass nipples and no more breakage.
    Tension's gotta be right too. In fact, before you buy anything, check the ERD on the rim and run it through a spoke calculator like Freespoke. Then your spoke length will be right.

    I have the same problem on an older wheelset. Could you just swap to brass and call it good enough?
    (Backup wheelset, not worth new spokes)

    Not really. You really need the spokes to end in the right place.

    Anywhere between the middle and right is ideal.
    Middle is minimum really.
    Brass nipples will mask this issue somewhat, since they are stronger than aluminum.
