3K or UD fork whit v-brakes?

I'm thinking to change my actually fork for a corrected rigid fork (CC-F0N65-29)and I have doubts about the material (flexion) working with v-brakes.
What material is more suitable for mounting v-brakes, 3K, UD or both?.
Thanks in advance,

Hi,
The 3K or UD refers to the finish of the fork, so the final layer. Both forks are perfectly suitable for the use with V-brakes.

Hope that helps.

Another question about the rigid fork CC-F0N65-29...

What is the outside diameter of the crown (black part)?
