THE PERFECT BLEND
The Polygon Strattos strikes the perfect balance between endurance comfort and race-inspired performance. Its geometry offers an upright position that reduces strain on long rides, yet remains aggressive enough for a powerful and efficient ride. Thanks to the carbon frame, the Strattos S7X weighs a respectable 9.11kg—perfect for crushing gran fondos or clocking up weekend miles.
EFFICIENCY AND SPEED
Building on the classic lines and styling of a race bike, the lightweight carbon frame features subtle aerodynamic cues on the tubing and internal cable routing to reduce wind resistance. Meanwhile, the stiff downtube, thru-axles, and wide bottom bracket ensure an efficient platform for power transfer to put down some watts!
ENDURING COMFORT
Don’t sacrifice comfort for speed. The Strattos features flex stays, dropped seat stays, and a seatpost with an internal wedge to absorb road vibrations, keeping you comfortable on long rides. The full carbon fork and steerer also reduce weight in the front end for improved comfort while maintaining precise handling.
A TRUSTED BRAND
Polygon has over 30 years of experience creating high-performance bikes at competitive prices. Polygon road bikes have led to numerous national titles and even a victory at the 2023 Tour de Taiwan. With a 5-year warranty, you can trust Polygon to deliver from the factory to the track.
