Braking surface rim cracks? (pics)
Vintage wheelset with mint-condition Ultegra 6500 hubs laced to CXP 23 and 33 rims. I'm trying to decide whether to just liberate the hubs for resale or leave the wheels intact. Rims have numerous surface dings--only cosmetic with the exception of these cracks-- 3 or 4 of them. Serious or what? Thanks.

I might be overly cautious but if you are sure they are cracks and not surface scratches then I would put them out to pasture. Maybe save them for some creative decorating of your walls. But cracks in the rims are a deal breaker for me. As far as I'm concerned, it's evidence that the rims aren't structurally sound and therefore shouldn't be ridden.

It's an odd place and strange way for a crack to form. If these were truly cracks, they've crossed a support beam (inside the rim) which is very strange. Also, they would have quickly grown out to the edge, especially because the brakes massage the rim.
Obviously, it's easier to judge with the rim in your hands than from a photo, but I suspect that these are deep gouges rather than cracks. Or maybe you can look inside to check.
Meanwhile, I'd ride the rims until I had a reason not to (this isn't one).

I agree, that looks like deep scratches. What does the inside of the rim look like? Can you locate the "crack" on the inside?
As long as the cracks/scratches aren't leading to spoke holes, you're probably fine. In a sense, the seam is like one really big crack, and I think on some rims, it may in fact not be reinforced.

With a scratch here.
Also, when did something that was still available as a new/current item in 2004 become vintage? there just a bit old.

adjective
1. of or relating to wines or winemaking.
2. being of a specified vintage: Vintage wines are usually more expensive than nonvintage wines.
3. representing the high quality of a past time: vintage cars; vintage movies.
so if you eat yesterday's high quality leftovers today, you're eating vintage food.

Looking at the wheel more closely, I'm happy to go along with the majority verdict----SCRATCH. Thanks, Guys!
