Carbon rim wear - how much is unsafe?

I have a Bontrager Aeolus XXX6 wheelset that is in pretty nice condition, but there is quite significant wear on the braking surface. The 'laser control' track is completely worn away, and I can see weave (but there are no loose strands coming through). It's quite hard to show this wear in pictures, but I can really feel the ridge when I run my finger over it. No idea where the limit is on this kind of thing.

I'd prefer not to bin them, but also would quite like not to die (I know this is inevitable, but a Trek-related passing wouldn't be very cool).

Hard to tell from those photos, do the classic credit card across the brake track and see if there's a lot of sunlight shining through the gap test

you can try corima brake pads or similar cork-type brake pads, they should ( at least the corima ones claim that) have very little abrasion effect on the rims and you should be able to squeeze many more miles out them.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
