My 05 Bianchi Pista frankenbike commuter.
This steed has gone through several phases in life: stock urban speedster bike, roadbike w/ bullhorns, and now it has been pressed into service as a commuter/townie.
I recently managed to get 32mm tires on it for a comfier ride as well as an SKS rear fender (not shown). These should let me do some light hardpack rails/trails, but they may be too heavy for my liking...we'll see.
Current gearing is 42x16, but I will be moving down to a 40x16 what with the larger tires and the stuff I carry in my bag to work.
