Strattos S7 Disc
Polygon
Race
Strattos S7 Disc is a carbon race road bike (2025), from Polygon, part of the Strattos family. This setup will suit riders who want a sporty road feel without a full race fit, with a setup that gives you a sporty riding position, while being best matched to paved roads. Its strongest points in the MatchBikes metrics 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, the trade-off to keep in mind 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.
