Frame damage? How worried should I be

just do some standing start sprint intervals and if your rear triangle doesn't collapse you're probably good

Noticed this when I was cleaning my drivechain this week—no idea how it happened as I haven’t dropped a chain since I got this bike and what’s more I have a chain catcher installed.
I tried the tap with a coin sorcery but didn’t feel like that was conclusive, and this really has me pretty bummed as this is my first carbon bike and I have been making huge strides since I picked it up a few months ago. Would really prefer not to have to ship my bike away for repair.
Thanks

Its tough to tell. It looks like a stone became lodged in there locally crushed the carbon? It there actually and indent there? If its damaged there would be some play when you push on it. Anyhow, a local carbon repair should should be able to fix it for a few hundred or less. This is minor.

Thanks friend. The thought did occur to me since it’s not really in line with where the chain would even contact it from slap or drop. The nice thing is it’s in an inconspicuous area as long as it’s structurally sound. It looks like a layer is missing more than an indent, more like paint than carbon, but then again I don’t know what I’m talking about. I don’t see any fibers.

The scuffs look superficial and the crease looks like a feature of the frame. If uncertain, pull the crank off for a better look.

You're fine. Keep riding.

I own a carbon fiber repair business. You are fine. This area in the frame is made to take this kind of stuff.

I've been riding a frame that u/illinihand repaired several years ago. Not dead yet. You can trust him at least a little.

Probably fine. Many carbon frames can take a terrific beating.

Get it x-rayed or ultrasounded by a carbon repair shop if you are worried.

Run that shit. You will have a hard time finding a bike without some minor damage to this area. Close tolerance, lots of power, road crap. If you don't have some damage down there, your Fredding it out.

Damaged? Yes, but not terribly. You've probably ridden with this damage a few times (unless you clean your bike like this after every ride) and didn't even realize it. Chainstays are moderately important, but this doesn't look to be so much damage as to be worrying at the moment, and you probably weren't close to the limits of the frame, so you had a little room to spare (be slightly more worried if you count yourself as a Clydesdale). And even if the chainstay does completely let go, the resulting crash will be more similar to sliding out in a corner than getting hit by a car.
You should eventually repair it, because if it happens again the damage will get bigger, and eventually become something to worry about.

Ouch. That looks more than cosmetic, I’d get it looked at for sure.
Edit: who downvotes that? Looks like a crater in the white graphic.
