Chain damage after each ride
Hello guys, I picked up a new Giant Roam 2 about 3 months ago, i've only put 200 miles on it. For the past 3 rides I been having an issue with my chain, it gets like a chew spot and I have to fix with a chain break tool and some sanding orherwise the chainink would get stuck. After fixing, the bike shifts okay but I cannot find what is causing this. Please see attached photos.
