This picture shows what the location of the panniers ends up being. Just a nice amount of heal clearance for my size 11s.
I painted it to match the rest of the bike, and I think it does a good job of blending in. Can't wait to ride this to work and see how she stands up.
I plan on building a few more racks. After that, I'll try a portier front rack. Something I've always wanted. For that I'll also need a new bike project to mount it to. Always searching.....
