The Campeur rack's dropout tang has 4 pre-dilled holes. These can be cut off to fit different bike designs. At this step, we had two choices. 1) cut to the lowest hole and mount the rack to the fender or b) mount to the second to lowest hole and not mount to rack to the fender. This bike will be going on trips where assembly and disassembly is needed, so we decided that ease of use is more important than complete integration. The last thing you want to do is search for 4mm long button-head screws when you're assembling a bike in an airport.
I'll leave you with a small teaser of the shall-not-be-named orange bike. Hypothesize away!
