Polygon strattos S4D Tiagra size XL

The Polygon Strattos S4D road bike is the entry-level model in the Indonesian manufacturer's Road Performance range. Built around a well-designed aluminum frame, this model comes equipped with an ACX carbon fork. The S4D also features hydraulic disc brakes and a 10-speed Shimano Tiagra drivetrain. The price is very attractive.

Regarding the bike's frame, Polygon's technical approach is quite astute. While aluminum has been the standard material for bicycles since the late 1990s, Polygon uses a lighter and more durable aluminum alloy than others. Starting with triple-walled 6061 tubing that is heat-treated for increased strength and durability, the ALX frames are designed to stand the test of time.

Furthermore, its fork is made from a high-quality carbon fiber. ACX is Polygon's lightest, stiffest, and strongest frame construction material. This is a scientifically engineered blend of Toray™ T700 and High Modulus M Series carbon. This process allows Polygon to maximize strength and stiffness in high-stress areas.

The Polygon Strattos S4D is therefore the ideal bike for those looking for an affordable yet durable road bike with high-performing components. The bike's performance and durability were designed by engineers with over 25 years of manufacturing experience. It is produced in the same factory as Marin Bikes, renowned for their high-quality and durable construction.
