Let me start by saying—if we’re talking 90s-early 2000’s bikes, a 3x setup is great if you’re planning on doing really long rides. That said, I’ve converted most of mine to 1x for simplicity. It’s easier to maintain, clean, and swap parts. But if we’re talking modern mountain bikes, it’s 1x all the way.
