Just another example of an innovation that gets misapplied. 1x11 is the best solution in some cases, but only if you understand the intended use. I take all front shifting off of our kid bikes because it is really just something else to go out of adjustment or break and they don't need more than one ring on front for their use. I like the fact that I don't drop MTB chains at all anymore. Other than that, no need to change.
