Is this safe to ride?
 

Just kidding. I'm not going to ride on it, just thought I'd share a couple pics. Rossin record, 35 year old tubular wheel. Probably 15,000 miles on it. I was just cruising along barely pedaling when it happened. The weird part is my bottom bracket came loose. Wobbly crankset. Pulled some serious faces on this wheel. Good times. Any similar experiences like this for

anyone?

That'll buff right out!

I had the same failure on a Shimano front hub, which I retired as soon as I noticed the defect.

JRA, huh? Sure...

Had a similar failure on a rear hub. Not sure if I rode it in that condition but I scrapped it as soon as I saw it.

I have a Campy NR hub that my buffing wheel yanked out of my hand and spit to the pavement. Slight hairline crack in the flange. It’s so shiny and pretty that I want to believe it will work just fine. Common sense eventually takes hold and tells me to relegate it to table art.

Should be fine with super glue, and duct tape. I'm not even worried about it.

I had a Normandy Sport rear hub that had served me well over many years of hard use. One day I noticed it was feeling kind of rough, so I opened it up for regreasing. The body had cracked on the inside, four big cracks on the drive-side bearing surface.

Unfortunately, yes:

I had it happen to an old Campy Record hub on my old Trek, touring in France, when I was 14. Basically identical to the OP's failure. We were in the town of Roquefort (where they make the blue cheese) - on Friday afternoon, of course, with little prospect of a bike shop being open on the weekend. This was 2002 or so.

Had to rig a bunch of spokes twisted and tied together in order to make the wheel true enough to ride the next two days until bike shops were open and we could buy a new wheel. I remember feeling really bad for slowing down the family tour, and my dad lecturing me about "riding light" and how hard teens are on components, or some such nonsense.

Really, the family shouldn't have equipped me with Campy racing gear for loaded camping. Looking back, I'm glad the flange cracked. Had it held and had I continued on that hub, I'm confident the axle would have broken - and aren't those Campy axles a weird thread pitch or something? I can't imagine trying to find such a thing in France in the early 2000s, knowing none of the language at that time. I remember the Monday after, my mom managed to pantomime a SRAM freehub and 9-speed cassette at the bike shop guy, and then my dad spreading the frame as it sat upside down on a picnic table near our campsite that night.
