That rotor is bent. You can look up YouTube videos about how to straighten that out.
It looks like your rotor is bent. The easiest fix would be to replace it. For that you need another center lock rotor, a tool to remove the rotor (e.g. https://ride.lezyne.com/products/1-st-exbbt-clt-v108) and a large adjustable wrench or hex wrench (depending on the removal tool you’re using). There are different options ways remove the rotor, check that the tool supports the right one (the leezyne). You don’t have to replace it with the same rotor but could go for something cheaper, as long as it’s the same diameter (160mm) and center lock (Not 6-Bolt). Don’t touch the braking surface with your bare hands.
Here’s a video by park tool explaining the process: [https://www.parktool.com/en-int/blog/repair-help/disc-brake-rotor-removal-installation](https://www.parktool.com/en-int/blog/repair-help/disc-brake-rotor-removal-installation)
You could also try to true the rotor with a truing fork (https://www.parktool.com/en-int/product/rotor-truing-fork-dt-2), but I have no experience and don’t know how well this works.
Fairly straightforward to fix, just bend it back. YouTube is your friend
You can bend it with a Adjustable spanner
Just find where the center of the bend is and give it a little tweak with an adjustable wrench. Make sure you use all good amount of the surface area of the wrench and be gentle until you get a feel for how much it’s going to bend. Save a few bucks and give it a try. Sometimes you might need to move the wrench an inch to either side of the bend to make sure you got it nice and straight. You got this!
