Strattos S5 Disc
Polygon
Race
Strattos S5 Disc is an alloy race road bike (2025), from Polygon, part of the Strattos family. It is a strong match for riders who want a sporty road feel without a full race fit, leaning toward a sporty riding position, while being best matched to paved roads. Metric-wise, it stands out for strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and an aero-leaning setup that still keeps some versatility. The main trade-off is a firmer ride feel than comfort-first options. Next step: compare this bike with other race models on MatchBikes.com.
