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 for long rides, yet remains aggressive enough for a powerful and efficient ride. Thanks to the carbon frame, the Strattos S8X weighs an impressive 8.21kg, 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 residence. While, 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 utilize flex stays, dropped seat stays, and a carbon 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 boasts over 30 years of experience and is known for offering 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.

SHIMANO ULTEGRA Di2
Nearly identical to Dura-Ace but lighter on your wallet, it boasts lightning-fast, buttery smooth shifting, a wide-range 11-34T cassette, and versatile 50/34T chainrings. Conquer any terrain with this workhorse groupset, renowned for its reliability, and exceptional value.

SHIMANO ULTEGRA DISC BRAKES
Hydraulic disc brakes are great for all riding conditions - easily boosting your confidence, even on the wettest of days. Aside from the versatility of hydraulic disc brakes, compared to rim brakes, they last longer, increase the lifespan of your wheels, and provide much more stopping power.

CARBON WHEELS
Upgrade your ride with the Novatec R3 carbon wheels, designed for discerning road cyclists seeking a lightweight, responsive, and durable wheelset. The 38mm rim depth strikes the perfect balance between aerodynamic efficiency and crosswind stability, wrapped in tubeless-ready Schwalbe One 28c tyres, this is a combo you can depend on.

CARBON SEATPOST
The Polygon Strattos' carbon seatpost helps to reduce road vibrations, providing a smoother and more comfortable ride. Its lightweight construction also helps shave precious grams, improving overall performance.

Outstanding! From start to finish…size, delivery as expected and the quality is first rate! Rode 62 miles yesterday and enjoyed every minute!

Buy one of these bikes.
My polygon strattos s8x has been fantastic so far. Sold a Trek domaine al3 to upgrade to the s8x and I’m so glad I did. The bike arrived with no issues and I was able to easily put it together myself. I did have my local bike mechanic give it a once over just to make sure.

Amazing bike for the money, perfect transaction, shipped very well protected. Highly recommended. Only thing I needed was carbon paste for rhe seatpost.
