Welp I screwed up my pedal install and my derailleur rubs in the front even after I spent a few hours adjusting it. Pedal felt funny while riding, I pulled over and it just fell off completely. My own fault for stripping it during the install. I think I'm going to just have the bike shop do repairs on my bikes from now on. The last two times I tried to fix something I just made it worse. Can't find the SHIMANO Claris FC-2403 30T/39T/50T x170MM ALLOY BLACK CRANK anywhere online in the US. Thoughts?
