Yeah, I figured that was the one you were talking about.
My Mark V is an awesome everyday bike. Semi-road geometry, and a higher BB. great frame for the money. The sizes do run a bit small however, based on the higher BB.
Mark V is more of a fixed gear style frame. (No fender eyelets.. smaller tire clearance etc...)
The Roy is alum... which is stiffer but will give you a harsher ride. Steel is much forgiving on the streets.
