Strattos S7X
Polygon
Race
Strattos S7X is a carbon race road bike (2024), by Polygon, from the Strattos lineup. It suits riders who want a sporty road feel without a full race fit, leaning toward a sporty riding position, and is best matched to paved roads. Its profile is strongest in areas like strong value-for-money versus many similar bikes, an aero-leaning setup that still keeps some versatility, and balanced, versatile speed for everyday riding. The main limitation versus more focused builds is a firmer ride feel than comfort-first options and more of a flat-to-rolling terrain bias than a climbing focus.
