With the Road Rocket we went ahead and indulged by designing our dream road frame. We have used our favorite tubing (Columbus MAX chain stays and down tube, Spirit seat tube and head tube and a skinny Spirit Keirin top tube & seat stays) to deliver performance in all the right places. The Spirit tubing is known as the lightest tubing in the Columbus range. The MAX tubing used is famed for its stiffness when you put the power down. The down tube has an oval shape which hugs the head tube vertically and hugs the bottom bracket horizontally, matched with colossal chain stays, the result is a speed machine with minimal bb and head tube flex.
The Road Rocket is a credible contender against titanium and carbon frames with all the comfort and durability steel brings.
This frame has a level top tube so measurment listed is centre to centre.
