Can someone tell me why they are so expensive? Are they better? I assume they would marginally lighter, but are there any other advantages?
There is no reason to go with an KMC chain. If you are just riding around going with a less expensive SRAM or Shimano option. If you are racing and want the fastest chain - it does make a difference, check out the friction facts results, but I would recommend either an Ceramic Speed UFO Chain or ICE-T Chain. For the DIYer I would seriously invest in the friction fact reports. I paid my $14.95 and the knowledge is invaluable in regards to what chain chain, the process for stripping the factory lube, and then the lube to reapply.
Hey Thomas, would you mind pointing out which report you are referring to? I went to the site and there are a handful there. Thanks
