But I wonder also if people are not making an overly big deal about derailleur capacity. Does anyone actually go big-big or small-small on a triple? The chainline is bad enough on a double.
The issue with “losing” the big-big combo is that if you accidentally shift into it - even once - there is a high likely hood of doing serious damage to some part of your drivetrain.
What the OP is talking about is having not just one, but several drivetrain-ending gear combinations.
I’ve given him advice on how to avoid this.
If you are going to lose gear combos, always lose them from the small ring, never the big ring. Do this by sizing the chain for big-big, and let things fall where they may in the small ring.
