The Polygon Strattos S3 road bike builds upon the success of the Strattos bikes from last year and is a new addition to the 2017 lineup. The Strattos S3 combines a new and improved ALX Endurance 6061 Aluminium frame with carbon fibre fork that is light weight and very comfortable, with an upgraded Shimano Sora 18 speed group set. 

The ALX Endurance 6061 Aluminium Strattos frame is built around an endurance road geometry. It has a longer headtube, which means that the handlebars are higher than on the more traditional race oriented road bike frame. This results in less strain on the back, and also reduces the reach to the bar – meaning you’re able to ride further, in greater comfort. The lower position of the bottom bracket and slacker angles on this frame also makes for a more stable, predictable bike for everyday riding - whether you are weaving through some traffic on your commute to work or carving your way down a paved, open road at your local national park. Additional to its comfortable frame, the Strattos boasts a front fork constructed of carbon fibre, which reduces the bike's weight and helps to smooth out the vibrations from the road.

The Strattos S3 is powered by a full 18 speed Shimano Sora R3000 drivetrain (Brand new for 2017). This includes front and rear deraleurs, shifters and even the crankset. The new Shimano Sora R3000 now comes with a sleek and lighter weight compact 4-arm double crankset and STI Dual Control Levers which was reserved only for Shimano's top of the line DuraAce groupset only a few years ago. The new Tektro R-369 brakes have also made things a whole lot safer with a 20% increase in rim brake performance over its previous incarnation.

The Strattos S3 is outfitted with a pair of Araya SA-730 wheels and wide, comfortable Kenda Kontender tyres. All of these features mean that this bike will outperform the competition and more importantly your expectations.
