I checked my chain for wear with my Park Tool Chain Checker CC-3.2. It is past .75% wear. Time for a new one.
How many miles do I have on this chain? Seems like a simple question. Unfortunately Garmin doesn’t provide a way to export my data. I signed-up with VeloViewer which is a 3rd party analysis website. The annual pro subscription is $13.40 USD. I’m impressed so far. They have some nice tools, charts, and most importantly ability to export all my activities.
I only have 1,645 miles on my chain. Sources say 2,000 to 3,000 miles is the expected life span for a 10-speed chain depending on riding style and conditions. Oh well. I’m not going to obsess on maintenance. I degrease and lube my chain 3 to 4 times a month. That is all I’m willing to do. I’ll get a new chain soon.
