The bolt heads get in the way of the arm so it won't spin freely. I don't have a vice to properly bend it. I was thinking some bolts that use an allen wrench to tighten them, that have flatter heads. Other suggestions and LINKS are appreciated.
Aha, this. I had to do this with my brake arm since I lack a vice grip.find a place on the sidewalk that is raised an inch or so, put arm there & smack it good with a hammer
Also if it isn't perfectly aligned it will cause a tighten and slack sort of problem on your chain. You think it's on there nice and snug, but on the other side of the wheel it'll be slack enough for it to fall off.Aha, this. I had to do this with my brake arm since I lack a vice grip.
On a side note, make sure your sprocket and pads are centered almost perfectly, the slightest deviation can cause some issues with the brake arm if you're not careful
