Carbon Wheel Damage
Hi. Was out riding my local roads on a sunny day on my relatively new all-road bike... and had the joy of experiencing tubeless tire blowoff. It was loud and fast and terrifying, but no wreck.
I was going about 20mph on pavement when my tire (Rene Herse Barlow Pass @ 45psi) completely popped off my rear rim (I9 250 Carbon TRA).
Rolled quickly to a stop — but because the tire totally ejected from the rim at speed, the rim rotated on the pavement a few times. And there's a bit of damage.
No pics attached because I haven't posted 10 posts... wish I could, but imagine a carbon rim that has skidded on concrete for about 5 feet. That's what it looks like. No cracks... just sort of ground down.
I'm new to carbon rims and tubeless tires, so I just don't know if I'm completely f'd here.
The question is: is a rim that has this kind of damage still rideable?
Thanks.

Standard answer is "it depends."

Right on. Thanks... did both things.
Here are some pics:

And went to my LBS... they seemed to think that the bead is still strong. Suggested a light filing of the rough spots and some super glue.

I am no expert but my carbon rim had less damage than that and my LBS said I should replace it. The bad part is where it has delaminated at the rim. Your LBS seems particularly ignorant in suggesting super glue, that stuff lasts about a week. Use epoxy if you are going to glue it.
Also don't put those tires back on tubeless rims.. many people have had problems with Rene Herse tires doing this.
