That’s not ‘bent’ from impact – the rim sidewall has been worn away by the rim brake. Time for a new wheel or rim before it fails catastrophically. Looks like it’s beginning to crack already.

The rim is about to fail. Catastrophically.
Tire pressure is pushing outward on the rim, and the rim is thin because of brake wear.
This can be dangerous.

Stop riding that bike. Do not ride until you have replaced that wheel. It’s on borrowed time, and it could violently fail at any moment.

It’s Time for a new rear wheel.
This one has been used to its full potential

if your rear wheel looks like that, its proper time to check on your front rim as well! a fail there is even worse than a fail on the back tire..

I love worn things. And yes this is worn. This is one of cons having rimbrakes.

Rim-brake rims are a consumable part, like tires or brake pads. It’s a slower process, but you’re there. Congrats on your 20,000 road miles / 5,000 mud miles.

It’s cool that this wheel has stayed in service for so long!

Did you know that the front brake is more effective in stopping a bike than the rear brake?
Use your front brake more often, learn how to modulate and feather your grip pressure so you don’t just suddenly ham fist strangle it and send yourself over the bars.
By using your front brake more, you will become a better rider and more of the rim brake surface wear will be dispersed evenly and you won’t ruin your rear rim so quickly.

Here is an in-depth article on [how to properly brake](https://www.sheldonbrown.com/brakturn.html) and turn.
In all seriousness, how has no one mentioned how amazing these pictures look? Idk, they just look so high quality to me, especially the last one!
It has ceased to be a rim and has transitioned to being scrap.
It’s not bent the braking surface has worn away which is perfectly normal and happens to every rim where rim brakes are used.
I’ve heard it too
Last time I saw a rim like that was shortly before it was blown to pieces by the pressure from the tire bead. Time for a new rim.
