Road Sportive Endurance
Sportive (aka 'endurance') bikes are closely related to road bikes - very light and fast, but with a greater emphasis on rider comfort
Geometry. As a rule, sportive bikes have a slightly more upright geometry than standard road bikes, which is achieved with a shorter top tube and longer head tube. This brings the handlebars higher and closer to the rider, meaning those all-day rides shuoldn't be such a stress on your back. This does result in a small loss in aerodynamic efficiency, but the greater comfort over long distances can translate into higher performance.
