There is a difference between the strut hitting the bump stops (usable travel), and hitting absolute bottom (absolute travel).

This is all part of the witchcraft and wizardry that is shock design. I'm curious Felix, when you had the damper apart, could you spot any shims or other internal damper design cues? As I understand it, it's all a matter of fluid control inside of the damper.

This thread is proving to be an excellent learning tool!
I suppose the range of suspension motion itself would also limit the likelihood of "topping out".
