we all say "oh I know it doesn't work, but I will never use it" which is good until you slam into that position without thinking..... which can result in a bunch of things including sudden deceleration (another ask my how i know

I set up my mountain bike with a short cage derailleur way back when to "be cool." I knew not to shift into large-large. Just a quirk of my bike. But when I let my uncle ride my bike, I didn't remember to tell him this and he had no idea about avoiding large-large, so he did it. And I had a two-piece derailleur thereafter!)
Already tested and everything seems to work correctly. But is better to test it out during a ride session.
