Can we finally move past the marketing hype and get a real explanation of how Shimanos chain technology actually improves shifting performance, or are we just supposed to blindly accept that its better because Shimano says so? It seems like every other post on this forum is someone gushing about how amazing the latest Shimano groupset is, but when you ask for specifics, nobody can actually provide any meaningful details. So, lets get down to business - what exactly is it about Shimanos chain technology that makes it so special, and how does it actually translate to real-world performance gains? Or is this just another case of bike industry smoke and mirrors designed to part us from our hard-earned cash?
