Tubus rack compatibility
I'm not familiar with the Ronin in particular, but I have the Tubus Tara on my Salsa Fargo, which has a very similar front fork setup, and it works fine. I had to use all of the provided spacers to get the rack to clear the calipers, but that's it. 

It can be a little tight and finicky getting everything lined up when mounting the rack and taking it back off, but it's not a big deal if you're not doing that very often.
