I was going to ask if I need to replace it but I'm certain the responsible answer is yes (comments welcome). How do I find and replace the outer chainring?
Specifically find the right model or compatible part and the dummys checklist for doing the task at home, perhaps some good links. According to the Kona Cindercone 2011 specs the chainring is the 44 tooth "42/34/24" (incorrect spec) on a Shimano FC-M521 crank arm.
Notice how I haven't even worn off the stickers... yes I am a newbie who either broke the tooth tumbling off an intermediate trail, or worse still hopping a curb.
