Did I lose the carbon rim?

Hi,
I used rigid plastic levers to get out tyre and damaged the rim sidewall.
Is there anything that can be done to repair it ?

Thanks

This is a pic you wanted to post?

Might be better to have seen it with the tire off. But it's definitely something you should watch closely before and after every ride from now on. Perhaps some epoxy resin or epoxy glue smeared on there might help prevent it from flaking and getting worse. Depending on your finances, getting another wheel might be the better choice. But if I didn't have the money, I'd still ride it till I saw doom and gloom about to happen with the wheel and hope that I see that before I'm involved in it.

Might be nice for others to know what brand and model rim this is. More heavily built carbon rims might be less of a concern. Super light carbon rims might be more of a concern. I don't actually own any CF rims yet. So I'm just guessing. I've ridden alloy rims that others wouldn't and never had a wreck or disaster from that. But is basically your acceptance or aversion to risk that you have to assess.

What's with the tire. Is it inflated? Left side of pic looks like the tire is sitting to low in the rim.

Welcome to BF.

That doesn't look like anything that would be caused by a plastic tire lever, or even a steel one. If the rim is damaged like that, it seems like you took a pretty good hit from a rock, pothole, or curb. Is the wheel toast? That's hard to say. You could sand the edges smooth and use it for years with no problem, or it could split tomorrow. Ya pays yer money, ya takes yer chances. Carbon rims are built to be pretty robust; but if it were me, I'd have a new rim on the way.

I haven't heard of that company but I wouldn't personally want to ride on damaged carbon but especially damaged carbon of unknown quantity or quality. Like others have said it could be fine with some sanding and maybe some epoxy or it could fail quickly and I don't know what it would be and I don't have the ability or want to find out.

It was highly unlikely to be caused by a plastic tire lever and if it was I certainly wouldn't want to ride on those rims as they are so poorly made it isn't even funny. Likely it was damaged in some other way.

Kobi I would highly recommend you get a new wheel and get it from a known quantity and quality manufacturer and take care of it. Keep your tires properly inflated and if you are hitting curbs and stuff like that more often I would look at something more robust and carbon might not be that material or if it were carbon maybe something like Reserve or the newer forged carbon stuff like Forge + Bond but if lightweight is the place you are going there is plenty of lightweight alloy rims out there.

I wouldn't ride that wheel if you paid me. But then, I paid good money for all of this dental work - don't want to risk it.

I have used plastic tire levers on several different carbon wheels for many years and never seen anything like this - and agree that carbon rims are strong enough to withstand the force of a plastic lever. That said - it is possible that a small crack or flaw in the rim that wasnt obvious could become obvious by using a lever on that exact location.

If I were the OP Id probably take it to a qualified shop and ask for their opinion before riding it.

Sort of a case of "If you have to ask."
If it worries you enough to ask, you'll be fretting about it on every ride. That would be a fun killer for me.
Maybe turn it around, Would you let someone precious to you ride on it?
