Polygon Strattos S7D Carbon Road Bike

A high-performance carbon road machine engineered with a UCI-approved aerodynamic frameset, internal cable integration, and a precise Shimano 105 hydraulic groupset for advanced competitive speed and distance efficiency.

Key Highlights

• UCI-Approved ACX Carbon Engineering: Handcrafted with an ultra-lightweight ACX All-Round carbon fiber frame and matching full-carbon fork. Features a 16% stiffer downtube profile to ensure immediate watt-to-acceleration transfer.

• Vibration-Absorbing Seatstay Matrix: Specially engineered with thinned, dropped carbon seatstays that actively isolate and dampen tarmac vibrations without sacrificing lateral frame stiffness.

• Shimano 105 Hydraulic Groupset: Outfitted with a complete Shimano 105 drivetrain and dual-control levers. Delivers lightning-fast, race-level gear transitions paired with an expansive climbing ratio.

• Streamlined Aero Integration: Features an advanced cockpit design where all shifting lines and brake hoses enter the frame directly beneath the stem, minimizing structural drag and ensuring a clean visual aesthetic.

• Flat-Mount Hydraulic Disc Brakes: Equipped with Shimano 105 hydraulic calipers acting on high-dissipation rotors. Provides immediate, effortless stopping power and precise modulation in high-speed technical descents and wet weather conditions.
