Broken spoke, I need help with searching for the replacement

[MickS]

Hey guys, I need help with finding a replacement for the spoke that broke on my rear wheel today. The wheel is SunRingle Duroc SD42 27.5 rim with SRC Boost 148 hub (j-bend spokes version, 32 H). I've tried to search for the spokes that would fit as a replacement. However, the spoke has broken at the very beginning of the thread. And as far as I know, the spokes are measured from the bend (knee) to the END of the thread.

That's the tricky part for me, because I don't know the nipple length, as the nipple is still in the rim and I can only measure the part of it sticking out. I know that there are some nipple standards, but I don't understand them yet. What I can tell about the nipple is the size of the spoke key which is 3.2 mm and the length of that square part is 6 mm. The broken spoke is 270 mm from the j-bend to the beginning of the thread (where it broke). If I would know the full nipple length, then I could subtract these 6 mm sticking out from the nipple length and use the result to add to these 270mm.

So, the question is if it's enough to "guess" the full nipple length when I know that the nipple needs 3.2 mm key and its square part is 6mm? Can you help? I'm happy to answer your questions if any additional information is needed.

I would pull out another spoke and measure it so you can order, or take that spoke to your LBS to get a matching one to replace.

Yes, do that, assuming you've asked Sun Ringle & they haven't replied? Your spoke needs to be within a mm or so of the original. Shorter & it will be weak, longer & it will pierce the rim tape.

Thanks guys! I don't know why I didn't figure it out myself, this sounds so obvious now, doh!
