Hi 53,
Haven't explored that option yet as I am very early into the life of the KMC X-10 chain that came stock on my bike. I am pretty vigilant about driveline maintenance so should get a good measure of wear from that chain. Reviews of the KMC chain are mixed...kind of like anything bike related...some love them others think they are junk. Overall I am pleased with the chain however may try another chain mfr. in the future when its time for replacement.
Cheers,
George
