De Rosa Solo 2019
The triple-butted tubing has an increased diameter without increasing the overall weight. The down tube has a 42mm diameter, and has semi-elliptical cross sections which optimize the torque resistance and increase stiffness in the bottom bracket shell area. The top and seat tube are 35mm. The seat tube can easily accomodate batteries for electronic groupsets. Tubing, dropouts, and steerer tube are all made using a CNC process, and all accessories are made with grade 9 titanium. SOLO for those who love custom-made titanium frames.
