Strattos S7X
Polygon
Race
Strattos S7X is a carbon race road bike (2025), by Polygon, from the Strattos lineup. Rider-wise, it fits riders who want a sporty road feel without a full race fit, with a sporty riding position, with a surface profile that is best matched to paved roads. Based on the metrics, key strengths are strong value-for-money versus many similar bikes, an aero-leaning setup that still keeps some versatility, and balanced, versatile speed for everyday riding. At the same time, compared with more specialized alternatives, the compromise is a firmer ride feel than comfort-first options. If this looks close to what you want, compare this bike on MatchBikes.com against similar models.
