I got about 23,000 miles out of my chain and sprockets and I only lubed them 4 times. My rear sprocket showed no visible wear and my front showed very little. The chain was shot but I probably could have gotten another couple thousand out of it if I wanted to chance it. What caused yours to wear so fast?

I learned all I need to know about life by killing smart people and eating their brains.
