I have a 2012 Kona Sutra touring bike. I am not happy with the front racks that came with the bike so I'd like to replace them with Tubus but I'm confused as to which one(s) would fit.

As you can see from the photo of my bike upright in the bike rack at work, there is a front caliper brake attachment point that may be used, there is a middle attachment point where the front fender attaches and there is an attachment point, currently unused, near the base of the fork.

I would appreciate some help with this, thanks.
