Stress cracks in rim

I trash picked an old Peugeot today, it's in rough shape but fixable. After a good scrubbing I noticed some small cracks around the spoke holes on the back wheel. Most are on the right side. The rims are dead true and all the spokes are tight, but I wouldn't say too tight or anything. The rims have no brand at all. The hubs are marked Normandy Made in France. How long might something like this last? The wheels seem solid. The most the bike will need is a set of tires and a few cables. I was able to ride it the way it is but didn't go far in the cold today. I was afraid my hands would freeze to the bare aluminum handle bars in this weather.

Strip the hubs from the rims and toss the rims in the trash.

It lasted you the 20 minutes or so it took to ride it home, so count yourself lucky. You NEED to change out that rim.

The hubs should be good - do a bearing rebuild on each one to inspect the bearing surfaces. Replace the balls with new ones.

Are those Rigida AL1320 rims? I had the same stress cracks on the rims that came on my French bike... looks to have the same shape as yours. If you have the other rim and it's an AL1320 with no stress cracks, and you are willing to part with it, I'll take it!

+1 on keeping the hubs but trashing the rim(s).

For what it's worth...when I decided to claen up my at the time un-riden 1985 Trek in about 2000, I (fortunately) noticed the rims had many cracks in the sides of the rims. When I say cracks...I mean cracks...when the tires were removed you could see thru the cracks. The rims likely had some 3000 miles on them (years prior). I had the wheels rebuilt using the original Maillard 500 hubs and new Mavic rims...don't recall the cost. I now wish I had got all new wheels, as it's very hard to find parts (such as cone nuts) for the old Maillard hubs.

Neal, that's awful.

I admit I had to peek at the file name. I was wondering what soggy toast had to do with anything.

Fwiw, I love French toast (and have a French tubular rim with a crack near a spoke hole that I continue to ride).

The rims have no brand markings on them and no grommets. They could be Rigida but I thought 1320s had grommets? These do have washers under each nipple.
Only about 10 spokes show cracks, and they didn't go out of true at all when I rode it, which surprised me in that I'm over 300lbs, and over 6' tall.
What's the worst that could happen? I wouldn't think that the whole rim would just explode all at once, at best I'd figure it would just start popping spokes after a while?
I don't ride hard these days, nor very far in this weather, so I figured I'd just run it till it gives out. Its a back wheel not a front so even if it locked up it won't be as bad as loosing a front wheel. Maybe I'll double up on the rim tape and rough them up a bit on a dirt trailer and see what happens? If it don't explode there I'll run them till they go while I look for a replacement rim?

What would be a good suitable double wall 700C rim to use that won't break the bank? They want a mint for anything vintage, or new old stock these days. If they were 27" wheels I'd be fine, I have a few spares but I've got nothing in 700C.

Yes, the rim is a goner but normally they don't fail catastrophically. Typically, as the rim deforms around the hole, the spoke loses tension and the wheel goes out of true. At worst, the nipple pulls though the rim. Either case is no worse than breaking a spoke.

BTW, my wife wants you all to know that the proper condiment for French toast is not syrup but ketchup. She argues that French toast is simply bread marinated in eggs and you don't put syrup on eggs. Fortunately, it's one of the few things we disagree upon.

Syrup is A1 as long as it's 100% real maple syrup from Ontario, Quebec, Vermont, or New Hampshire. Well, OK, Pennsylvania and New York make good maple syrup too. At a breakfast buffet table in a little hotel in Appenzell Switzerland there was, of all things, maple syrup imported from, of all places, Canada.
No French toast though.

The way I see it, the whole thing was free, I have to spring for some bar tape and new tires, beyond that, it should be fine, if a better wheelset shows up, I swap it out but for now I'll just loosen the spokes in the holes with the cracks double up the spoke washers inside, tap the cracks closed and use a bit of JB weld on the area and once it's dry, I'll retention the spokes.
I'd bet money that it'll buy these a good bit of time before they fail.
I thought I got lucky today, I trash picked a no name bike with two nice looking Weinnman rims that are a dead ringer for these but their 27" not 700C. The rear would work but the front won't go unless I run a super small 27" tire. The Mafac calipers would reach either size, and both have quick release hubs.
I also pulled the handle bars off and have them soaking in a bucket of gas to get about 5 layers of duct tape and black electrical tape off. I also don't like the hollow stem on this thing, I broke one years ago and got lucky, I don't care to tempt fate twice. I tried one from another bike but no go, the hole is smaller just enough that it won't fit.
Here's another pic, this is the worst hole out of the ten with cracks. Two are this bad, the others show far less damage. All of the spoke holes are bulged a little bit, the front wheel is too but not as bad. If the rims weren't dead true with a decent braking surface, it wouldn't be so bad. Besides, what would I use that would look right on an older bike in 700C rims? They have to match the 36 spoke Normandy hubs.

Grab a set of wheels from a cheap and/or junked "donor bike", or buy a set of new rims and rebuild the wheels as a winter hobby project. If you haven't built up a set of wheels, you can get how-to information online and be on your way to developing a great new skill that can come in handy.

27" rims .... https://www.niagaracycle.com/index.php?cPath=123_379
700c rims .... https://www.niagaracycle.com/index.php?cPath=123_380

Check out the prices these guys have for tires, cables and everything else. Many are unbeatable!

Trash 'em. Rims do not last forever. They will eventually blow up. This is what happened to one of mine after ~15 years as a daily commuter:

Most people do not ride their bicycles enough to allow the rims to get to this point. I've only seen this a handful of times and generally there was a big, deep circumferential score from something embedded in the brake pad. However, I have seen several ATB rims which were getting dangerously close, having a pronounced concave sidewall, which is not suprising given the conditions they're ridden in. Commuting would be better, though not much if you're an all-weather commuter. No doubt, disc brakes are the solution for this sort of problem but lacking that, periodic inspection and picking foreign material out of pads will help delay the process.

BTW, great pic for your avatar. Given you location, I assume that was taken on the Charles? We were down there this past October, watching my son's crew win their event at the Head race.
