bought a bike secondhand with bontrager carbon rims. went to put new tires on it and saw these chips on the inside of the back rim. is there any saving this or should I bin it?

Hard for me to say based on pictures alone. I would do a tap test with a coin to see if the carbon is dead in the surrounding area. If it is, then look to replace
Doesn’t look particularly concerning but it’s a bit shit.
You could get a local composites repair shop to take a look and see if they can fix it.
I think the general consensus is that rim bead damage can’t be repaired (or at least repaired easily).
Having seen (in the shop and on the trail) dozens of these rims fail, I’m not sure I’d care about this ding. I’d put some epoxy on it, smooth it out and wait for the rim to explode itself shortly from something unrelated.
