I'm considering re-building a front wheel. I'd really like to avoid buying new spokes, as the cost will start to be more than I think the job is worth. Currently, I have a Mavic 622 x 19 s-6000 rim (according to the sticker), and i"m thinking of replacing it with a Mavic A319. Given that I currently can't measure the rim diameter to the nipple seat, nor the spoke length (as it's in use on my bike), nor can I find that dimension for the new rim, is there any way to be sure that I won't need new spokes?

To reuse spokes, the old and new rim would need to have matching ERDs. You need measurements from both rims to know if that is the case.

If you have the rim available, you can compare the diameters of the hubwards face of the rims. If the same, within 1-2 mm, the rims MIGHT both build up with the same spokes.

Do note the "might", you do need to check where spoke ends sit in the nipples in the current wheel before you do any guesstimates.
If the spoke/nipple fit is already on the short side, then going to a rim with a bigger inner diameter might blow the whole deal.

Use a spoke length calculator to see what the new rim would require with your hub.

You could remove one spoke to measure to see if the length is correct.
If it won't work, pick a rim that does.

Is there something wrong with the current rim?
Have you ever rebuilt a wheel with used spokes? If the nipples are corroded, it can be a real pain.
Use new nipples and wire brush the old spoke threads well. It'll be a lesser pain, but still worse than new spokes & nipples.

Thanks for the information, Bill. Sounds like it may be more of a pain than it's worth to try to re-use spokes and nipples - maybe I should just shoot for the rim and hub I want and see how it ends up. As I can't find the required dimensions for the new rim I want, I think I'll just have to do this anyway.

The current rim is nearly worn out. I have re-built a wheel with used spokes (and nipples, and rims - don't even ask). They were in fact my first, second, and third attempts at building a wheel. This will be my fourth....

Actually same rim and you can tape them together and then move the spokes from damaged to good rim without disturbing the pattern.

But it reads that the only thing remaining the same is the Brand and the tire it will use.

Be careful with right and left facing spoke holes.

So far I've been avoiding Mavic wheels and rims since they use a lot of proprietary spokes and nipples. Just be careful with your particular application.

Why don't you write to MAVIC and ask the ERD on the two rims.

I'm not sure how close of a match you need. Maybe within 1 or 2mm, depending on whether Mavic specs their spokes long or short.

Are they bladed spokes? It is possible to cut and thread roll spokes, as long as you don't get into the butts or blades.
