digital chain checker

Take all the guess work out of checking your chain wear and let KMC's Digital Chain Checker do all the work. There is eve a guide that tells you whether or not your chain is still good for riding or if its time to replace.

Thanks for posting. It's not obvious that you don't zero out fully extended, then read the number once under pressure from the chain. Some change to the product design to remove that question would make this product even better. For now I always have to reference this video when checking, as checking my chain is an infrequent operation.
