The tested road geometry puts the rider right in the sweet spot of power and control. The result is a bike that feels like an extension of your body. You think it, and the Tommaso Velocita does it. The 6061 aluminum frame is light and stiff enough for accelerating while complaint enough for the 6-hour rides in the summer.
