Oooh! Centurion.
I have a "Centurion Made" Diamondback Master TG. My only bike. Great for my commute, fun/fitness rides, and light errands. Crank Bros. Candy C, Bontrager saddle, lights, TransIt seatpost rack, Specialized Armadillo tyres. I kind of like the quirkiness of the marble...but I'm considering stripping it down and getting the frame powder coated a flat black.
