I've seen more rear ders damaged from chain suck than fronts.
This chain suck problem is one big reason to learn how to shift better. Andy
Chain suck isn’t a shifting problem. It’s an equipment problem. The chain hangs up on burrs on the teeth of the chainrings and is pulled upwards. Often it will release with tension but not always. It’s also worse with smaller aluminum rings.
