Choosing the right replacement for a snapped rear-wheel spoke

Okay, here's the problem.

I broke a spoke on my rear 24h Bontrager Select Rim/Hub. So now I'm trying to figure out what spoke I need to buy to replace it.

This is the first time I've ever had to replace a broken spoke. Everything I've read indicates that I need to take a ton of measurements like finding the rim diameter, flange diameter etc. (down to .1 of a mm) to find the right spoke. To do that, I'd have to almost tear the whole wheel down.

If I took it into the LBS, would they do all that? Or would they pick a spoke from a table showing the lengths for the model of my hub and rim? Is there any place online that has such a table?

Do you guys take all these measurements to repair your broken spokes?

Hope you guys can help. ;-)

You have at least 11 other spokes to measure.

Yeah. I'm probably overthinking it. Could I just measure it from nipple end to hub?

Just take the old spoke to the LBS and get a replacement.
Assuming it broke at the bend and still has at least a "trace" of the bend left, that's all you need.

Not quite advisable, as that may throw you off a few important millimeters of insertion depth. What I'd do is to have a good look at where the old spoke broke, which is usually right at the bend - and how the spoke ends sit at the nipple. If the break is at the bend this time too, bring the remains to a lbs and have them pick out a replacement for you. If needed, adjust a little to get better nipple overlap.

It's also possible to pull an intact spoke out, and measure that one. On low spoke count wheels it may be appropriate to reduce tension in the whole wheel first.
