It's amazing what you find when you pull a wheel off for a new tire. My 2 year old sprocket is worn out. The leading teeth have a burr on one side. Also the spacer that goes into the sprocket assembly looks like a pulley belt in that it has two 1/8" ridges. One section of each set of cush appear to have been crushed. They are misshapen.
Is the cause of these defects related?
