Small crack in rim near one spoke—should I stop riding immediately?
I noticed a small crack around one of the spokes in the rear wheel of my Ksyrium Equipe wheels. I inspected both rims very closely and it is the only spot with any signs of cracking. Should I stop riding it immediately, or is there still some (safe) life left in it? See picture below. Thanks!

Well that certainly appears to be a crack to me from the photo. If indeed a crack, then personally, I wouldn't ride it much more than around the neighborhood myself to check adjustments, etc. if I worked on the bike. Others with more experience with Kysrium rims may chime in.

I’d say don’t ride it. That said, I had a crack in a wheel I didn’t notice for over a year and nothing bad happened but could have. I had a creaking/popping noise and couldn’t figure it out until the crack got stuck “open” and I snagged my wash cloth on the rough edge while cleaning it.

If it were a front, I would definitely stop riding it. But as it's a rear, my curiosity would have me pack a spoke wrench and keep riding it to see what happens.

I don't think it's a big safety concern but with that few spokes in the rim it will just keep getting worse, will probably go way out of true at some point and could ruin a ride. You could drill a small hole at each end of the crack if you can't get it replaced right away which would slow the growth of the crack.

The crack will stop growing when the stress is released, when the spoke no longer has tension. Many riders have gone many miles more with cracking spoke nipple holes w/out issues (other than wobbly wheels) This is no worse than riding with a broken spoke. Of course wheels with stupid few spoke counts will see more wobble, when this happens, than a wheel with a higher spoke density will.
But I always like these "should I still ride the bike" type questions. Or the "how much more can I ride the bike" ones. The bike (or wheel) is telling you that it has given up it's life for your pleasure and ideally should have already been replaced. Andy

Rear - Ride it until you get a replacement, but start that process now.

Over the years, I've replaced a number of rims with cracks like that.
I always found the crack when cleaning the rim, and never had a catastrophic failure from one.

I had a rear rim with a couple cracks like that after a few thousand miles. I have no doubt the cracks had been there for some time before I found them. I procured a new rim and spokes, which took a while, then re-built the wheel. I doubt such cracks are likely to fail catastrophically, but I considered it a "courtesy warning".
