New for this year, the Polygon Strattos S5 replaces last year’s Helios C5.0. This is Polygon's top of the line alloy frame / carbon fork road bike and is aimed at avid road cyclists, sportive regulars and everyday commuters. This bike combines a lightweight, durable and reliable alloy frame with the proven performance and popularity of the Shimano 105 22 speed gear set.
The completely redesigned Strattos frame is made of Polygon's ALX Advance Endurance 6061 Hydroformed Aluminium and the result is a frame that is both light weight and yet extremely stiff when the time comes to push hard on the pedals.
A Shimano 105, 5800 22 Speed groupset propels the Strattos S5 forward and adds understated performance to the bike. A full compact drivetrain, with frame-size specific crankset length, a 50/34 tooth crank, and an 11/28 tooth cassette ensure you can keep a high cadence on the steepest of uphills and yet gives you enough gears to sprint downhill. Similar to Shimano Dura Ace and Ultegra, the 105 crankset now features fixed BCD, meaning you can swap the chainrings to 53-39T, 52-36T or 50-34T all using the same crank arm spider and there is no need to replace the whole crankset.

Shifters and brake technology have also been trickled down from Dura Ace and Ultegra gruppos, with slimmer and lighter shifters for the new Shimano 105, and “real” dual-pivot brakes that increase braking power and modulation by 30% when compared to previous versions.
The wheelset on the Strattos S5 is the new Entity XL2 clincher. The XL2 features sealed bearings, semi aero rims with 30mm profile, 28 spokes front and back, oversized freehub engagement pawls and a machined alloy brake surface This results in wheel that exudes quality and. The XL2 is one of the lightest wheelsets in its category which has allowed it to keep rotational mass as low as possible, improving acceleration and handling. Matching these wheels are Schwalbe Lugano 25c tyres keeping the Strattos S5 rubber side down at all times, with plenty of grip on dry and wet roads plus Schwalbe’s Active Guard adds puncture protection so you can rest assured the tyres are going to handle the roughest of road terrain.
Completing the Strattos S5 is Polygon’s in-house brand for components, Entity. This includes triple butted alloy bars, alloy stem and alloy seatpost. The Entity saddle is slim in profile and long, allowing for you to shift your body weight on the bike when attacking an uphill or tucking into the downhills.
