I don’t see any posts where this has been thoroughly hashed out. I’m curious what everyone’s thoughts and experiences have been with specific chains and the quality of the shifting on any given set up.
My own experience has been when I moved from 10 speed to 11 speed the shifting has not been great when I use Shimano chains. Now I’m not sure if that’s a tolerance thing or a cassette issue.
For 11 speed, I’ve used KMC silver, KMC EL, Wipperman silver, and Premier treated chain.
When properly cleaned and lubed or waxed, they all shifted equally well.
I’ve only ever really used KMC X11-SL DLC 11 or Shimano Dura Ace HG-901 over the last few years on my tri and road bikes across 11 speed Etap and Dura Ace groups. I also run Rotor rings so shifting can be a little more fickle but I find the Shimano chain changes better and is cheaper so I generally lean towards Shimano now days. Not that I regularly cross cassette fully but if you do the Shimano has no issues but the KMC doesn’t seem to like it as much as you get close.
I recently bought some praxis chainrings. In their faq, they recommend pretty much any chain except SRAM. They don’t seem to think sram chains shift as well as others.
I haven’t personally experienced a difference, but I usually buy Dura Ace anyway.
Pretty much same shifting performance on 105, Ultegra, Ultegra Di2, and eTap with SRAM Red, Shimano (multiple), and Premier chains. For me, different chains have no material difference for shifting.
