Compression Style Steerer Caps
Is this kind of steerer cap:
a better option than a star nut?
Do they provide any advantages in setting pre-load?
I guess it's not worthwhile replacing a star nut with this just for the heck of it, but would it be worthwhile changing over to this style when I change the headset?
They are designed for carbon steer tubes that might get cut by a star nut. Better option? It's easier to remove.
They are REQUIRED for most carbon steerer tubes but offer no advantage if the steerer is steel or aluminum and can accept a starnut safely. They weigh more and cost more.
