KMC Test Chain - 1000 Miles

With just over 1000 miles on or KMC test chain (see original article below), we have noticed some wear to the paint. The outer links on the outer drive side show about 20% wear, mostly on the center portions due to the cassette teeth while down shifting. The inner side of the chain (the side against the frame) shows much more wear with about 50% of the paint gone. As you can see, most of the wear is found on the outer X-Bridge links as well as the hollow pins. This wear is attributed to repeated upshifting up the cassette. Other than the paint wear, the functioning of the chain is still perfect. Shifting is smooth and the wear life of the chain seem unaffected. Look for future updates.
