Actually, it doesn't bug me at all visually, and I really don't care that they installed the wrong one as long as it's not a big deal functionally. I guess it would have been nice if they'd said: "we would have to order the exact spoke, but we have one in stock that's slightly thicker, but it will work just as well". I assume they used what they had in stock rather than make me wait for a special order. It's a small shop and I don't really expect that they'd have every spoke in stock. Frankly, I was a little bit surprised when they told me they could fix it within a day. At least it's the same color. Heck, even if they'd said they could replace it, but with a silver spoke instead of black, I wouldn't have cared.JCavilia said:Personally, I wouldn't bother. You'll never notice any difference without looking close, and it's highly unlikely it will ever affect the performance of the wheel. A spoke of a different diameter will have a slightly different elasticity, but it really won't affect anything. They probably didn't have a spoke of the right length and diameter, so they used the other one. I've replaced lots of spokes with not-quite-identical ones. No biggie.
If it really bugs you, you could take it back and insist. But it really makes no difference.
