It is important to determine the correct size of the bike for comfort and better control while cycling.

The Polygon Strattos S4 is an aluminium road bike for riders getting into structured road cycling, fitness riding or longer weekend distances while wanting dependable Shimano components and a more comfort-oriented position than an aggressive race bike. Within the Strattos S range, it steps up from the S2 and S3 with a Shimano Tiagra drivetrain, while retaining the simpler rim-brake layout. Compared with the S4D, it is the choice for riders who specifically prefer conventional rim brakes rather than hydraulic discs.

Comfort Meets Efficiency. Polygon combines its ALX road frame with an ACX carbon fork designed to reduce road vibration and hand fatigue. The drivetrain provides closely spaced road gearing for maintaining cadence across flats and climbs, while the compact crankset keeps steeper gradients manageable. Internal cable routing through the downtube also gives the frame a cleaner layout without turning the bike into a highly integrated system that complicates routine workshop servicing.

Practical Road Platform. The wheelset uses tubeless-ready rims, giving riders the option to convert later with compatible tyres and the necessary tubeless components. Quick-release hubs and conventional rim brakes also keep wheel removal and general maintenance straightforward. Pedals are supplied, making the bike usable without immediately purchasing a separate pair, although riders moving to clipless pedals can upgrade them independently.
