A mid-fork mounted Porteur rack for John Speare's 650B Trek 520. I built most of the rack beforehand and added the stays and backstop when he brought the bike over. The project took about 12-14 hours total from start to finish. You can find photos of the build process in the Rack Building Howto gallery.

I'm very happy with the results except that the rack sits a bit high off of the front wheel. I look forward to seeing what John thinks of it.
