Broken Spoke Nipples
I have a Mavic 719 Disc rim laced to a DT Swiss hub with 32 spokes. This is the back wheel on my bike. What keeps happening lately is spoke nipples breaking off. I've had issues with broken spokes before on different wheels where spokes break near the flange of the hub but this is my first experience with the nipples themselves breaking. Does anyone know what this indicates? I think there may be some uneven spoke tension on the wheel that is causing this but am not clear on why the nipples are breaking instead of the spoke. Is one kind of nipple stronger than other kinds? I'm using regular brass nipples on this wheel. Are alloy nipples stronger? Thanks for any advice.
