I have a Kona Sutra (see below) that comes with a front rack. However, I'd like to use a different type of front rack, one that will both hang front panniers as well as have a shelf type top. The problem is, as you can see from the photo, the current front rack is designed to use the (optional) cantilever mounts as well as a pipe-type clamp around the rather thick forks. I've looked a bit but I can't find a front shelf rack that would work on this bike.

Help would be appreciated.
