The frame and fork of the Steamroller isn't conducive to adding racks, so to add carrying capacity I added a Revelate Tangle bag, which carries U-lock or chain and padlock, small tools, etc. And the seatpost has clamps for both a Carradice Tour and a Burley Travoy.

Other goodies include Nitto Moustache bars, Michelin Krylion 25mm tires (~27mm actual), Selle SMP saddle, and SwissStops on the front brake. Gearing is 50:19 for 69 gear inches.
