Hi Guys,

I know this has already been discussed somewhere in this forum, but I am looking for a tolerance/indicator for chain wear, based on pulling the chain off the chainwheel. My bike has Ultegra 9-speed components, and I noticed slight "hooking" of the large chainwheel's teeth. This is the original Shimano chain, and it probably has 5-6000 miles on it (never ridden in the rain).

Thanks,
Harry
