I’ve been having some issues the past couple of days simply changing my back wheel innertube (turns out I need one that isn’t that common) and today whilst trying to put a new one in, my tyre was insanely difficult to put back on.
I’m wondering how easy carbon rims can dent, and have I done this with a plastic tyre lever? I would’ve thought the plastic would break before carbon would bend… but I don’t know.
Also any ideas on whether this will affect the wheel…

Are you sure that’s a carbon rim? Carbon flexes and if you keep pushing it snaps
That is not Carbon. Carbon wont dent it will crack
Pretty sure these are alloy fam. I think carbon would break.
To your point thought, ive done this with my dtswiss hoops, theyre the r470 and were easy enough to bend back with the right tool and some finesse. It rides the same although it bothers me and gives me some worries about a tire blowout but its fine for the most part. Not caused by a tire lever, something more like hitting a curb with low tire pressure etc
That ain’t carbon my guy.
Good old continental gp 5000 😐
What dt swiss tire is that?
Carbon does not dent. It breaks.
Carbon?🤦🏻♂️
To answer your question about if you did it with the lever it’s unlikely. These rims are easy to bend with strikes if they’re what I think they are (DT r470 db) and you probably just hit a bump or something while under-inflated. Unless you’re using metal levers or really just going insanely hard on them I doubt it was the tire install.
It is extremely difficult to dent carbon. That is aluminum
Pretty much impossible.
I’ll skip the obvious comment, as you are already well aware of that bit. That’s a pothole or curb that’s bitten your wheel by the looks of it. Possibly also caused your puncture. You “shouldn’t” bend aluminium rims, but i probably would for something that small. Put a bit of your old tube over it (to protect the paint) and bend it with some pliers.
As to getting tight tyres on, get one side fully on. Put the tube in. Put as much of the other side on as you can, starting by the valve. Hopefully, you can get it about 75% on. Then run your fingers between the side that’s completely on and the rim, pushing the bead into the middle of the rim. Then do the same on the other side, working from the valve again. You should be getting further round. Once it gets closer, you may be able to push it over with you thumbs. If not, use plastic levers to force it over, being careful not to pinch the tube.
What’s weird about your tubes, though? 650b?
Your plastic levers are pretty tough guys, but it should be fixable. Every fault is the way how we learn. I was putting one-time vittoria tires on brand new carbon wheel deep wheel and lever slipped and made a scratch.
Take it to an LBS and have them bend it back with a rotor truing tool. Or get a rotor truing tool. Best thing I’ve found to not tear up the rim.
Uh oh
Dat aint carbon my friend
That’s not a swanky as you thought!! Bend it back and ride on.
That’s not a carbon rim… carbon doesn’t dent… it’ll just crack. But regardless… always use plastic levers.
