Weinmann concave rim differences
A fellow BF'er was nice enough to part with a 700C Weinmann concave so I could have a pair to lace this winter.
But comparing the rims side by side it seems that my rim is wider.
Were there different rim widths in a 700C Weinmann?
I guess I'm back to square one.

What size tire are you using? Do they have to be the same? You can pick a tire that will work for both. Have you measured the difference?

The difference is the width of the lip, or about 1/8 of an inch. I worried that the tire will develop a taller profile on the narrow rim.

Yes, there were two models of the concave rim: the A-124 was a narrow rim, and the A-129 is a wide rim.

You could always use 1 1/4 in the rear and 1 1/8 in the front.
I run mavic rims 21mm rear and 18mm front every now and then.

I guess if I can find another one I will get a matching pair. I'd rather have the wider rims as they are going on a touring frame.
I know its a bit anal. I don't think anyone would ever notice that the front rim was narrower than the rear but I'm a picky guy...

It's hard enough to tell the difference in width with the two rims stacked up next to each other; There is no way anyone will know there's a difference after you build the narrow one into a front wheel and the wider one into a rear, put tires on them, and put them on a bike.
Remember English bikes used to come with a 40H rear, 32H front; so it's normal and right to have the stronger wheel in back.

I think you're being a bit too anal. They look virtually identical, and 1/8" will barely affect the tire profile.
I have run across Weinmann concave rims in four configurations - 27" without eyelets, 27" with eyelets, 700c without eyelets, 700c with eyelets and the already mentioned two widths offered in the 700c line.
For my money, if I am going to take the time to restore or refurbish a bike, I would want the rims to match. Anything else would not satisfy my own anal nature.

In reference to my firs post regarding the different concave Weinmann rims I have run across, allow me to add one more configuration - 26" for use on early eighties mountain bikes. Raleigh often times fitted them to their bikes.

This may be a daunting task to find the correct rim.
It would be soooo easy to just give in and buy some modern rims......
