Had to "thread the needle" last week and was unfortunate enough to be on the downstroke when I swerved and caught my pedal on the sidewalk curb HARD. I kept it together and avoided a potentially life-endangering scenario, but I noticed that I did bend my main sprocket a little bit. Now the wobble is enough to just fit within the boundaries of my front derailleur. The chain sometimes rubs against the edges of the cage depending on what gear I'm in. It doesn't look like I bent the frame, but I'm wondering if it's okay to run it like that, and if so for how long. Should I replace the crank or can I just get away with replacing the outer ring? I commute on the bike 14 miles round trip every day. My bike is a 2010 Surly Long Haul Trucker with what I believe is an Andel RSC6, 26/36/48t. Thanks.
