Why is my chain snapping off the sprocket?
You can hear in the video that grinding/ snapping noise, and it's like the chain is under tension and wants to go sideways off the sprocket in certain places. It's also making the bike not want to move forward, the bike slows down at this spot in the chain. I just oiled the chain a couple days ago and it seemed to help, but this problem came back quickly.Any idea why this is happening and how to fix it?
