I have wanted to build a classic Roadster for quite a while. This twitchy criterium frame may not have been the best choice, but the hyper-active handling matches my environment well. One big advantage of this frame type over 26″ wheeled bikes is the ability to lock the frame and rear wheel to a parking meter with a mini u-lock.
Those handlebars really make a lot of power, surprisingly, and there are other advantages. There is a slight aerodynamic disadvantage at high speed, but I usually get down on the grips at the center of the bars and out of the wind. This is a hot bike for the street.
That is a 1992 Cannondale C600 Criterium racing frame.
