Old Man Mountain rack, which attaches through the rear axle so you don't need braze-ons.

And then I use a single Arkel commuter pannier, which has a detachable shoulder strap so it's comfortable to carry around if I'm not on the bike. There's a little pocket at the top for my entry pass to the bike storage room, and I stuff the strap into one of the side pockets when I'm on the bike and not using it. Keys fit into the other side pocket. They really thought this pannier out. I love it.



I tried riding with a backpack and with a messenger bag and hated both. Back got sweaty, and I felt totally off balance all of the time.
