How much are they really worth the upgrade?
I know most, if not all of us would like to get a really nice CK headset, but thats talking in ideals, and i want to dip into realism if i may? If you had a Zero Stack headset for example. Pretty basic, nothing special. Would you bother to upgrade it to something better? Money is a factor obviously, or we would all be riding 4k MTB's.
So yay or nay? Is it really worth it?
