Ritchey Crown Race Question

[adamhell]

hi PL,

I am hoping someone can help me with this one question. I have a Ritchey Ultra frame and the headset it comes with, but I want to use a Surly Karate Monkey fork which has a straight 1-1/8" steerer. Can anyone please tell me if they make a crown race that adapts the oversize lower bearing to the 28.6mm steerer. If so, which one is it?

The part that is highlighted in the image on the right should be correct.
The lower headset bearing in your Ultra frame is the same as the one used in the ZS55 & ZS56 headsets.
