DESCRIPTION FAQ Product Reviews Store Reviews Size Chart

The Polygon Helios A8 brings pro-level performance to a more accessible tier. Featuring the same ACX carbon frameset developed with elite athletes, it’s paired with Shimano’s Ultegra Di2 electronic drivetrain, a power meter, and carbon wheels—delivering speed, stiffness, and aerodynamic efficiency in a lightweight, race-ready package. BUILT FOR COMFORT Comfort...

BUILT FOR COMFORT

Comfort and performance go hand in hand on the Helios A. With clearance for up to 34mm tyres, a simple swap boosts compliance and unlocks true all-rounder versatility. The updated cockpit with a flared handlebar and ergonomic flat tops further enhances comfort while improving control and stability, all without compromising speed.

ENGINEERED FOR SPEED

The Helios A series was obsessively developed over three years alongside elite athletes, with a focus on aerodynamic performance and race-day reliability. The new frame is paired with a new front-end fork profile and optimized tubing shapes to cut drag and improve control – the result is a frameset that climbs fast, corners sharp, and descends with confidence. It’s supported by the Terengganu Polygon pro team—fast, efficient, and dialed.

LIGHTER. STIFFER. FASTER.

The new Helios A delivers a high-performance experience from the first turn of the cranks, with an exceptional blend of stiffness, lightness, and aerodynamics. The re-engineered 880g (size M) frameset is 150g lighter than the previous generation, yet offers greater torsional stiffness thanks to a reinforced front triangle and refined ACX carbon layup.

REVISED FRONT-END FORK DESIGN

The updated fork features increased surface area, optimised rake, and smooth transitions for improved aero performance and front-end stiffness, all while weighing just 420g. Engineered to reduce drag and sharpen handling precision during high-speed descents and sprint finishes, it delivers a confident, race-ready front end without compromise.

ACX PERFORMANCE CARBON FRAME

The Helios A7 frame employs optimized fibre orientation and controlled wall thickness to maximize stiffness-to-weight ratio. This engineering delivers UCI-approved race performance with a balanced ride quality that preserves comfort. Every tube shape and layup has been tuned for efficient power transfer without sacrificing compliance on long race days.

SHIMANO ULTEGRA Di2 + PM

The 2×12 Shimano Ultegra Di2 groupset delivers lightning-fast electronic shifting with pro-level responsiveness. It’s race-proven tech that offers consistent performance and precise control, helping you stay fully dialed whether you’re attacking climbs or sprinting to the line. Built with durability and reliability in mind, it ensures seamless operation ride after ride, no matter the conditions. Comes with optional Power Meter.

LINC BETA CARBON DISC WHEELSET

The LINC Beta Carbon Disc Wheelset features a 45mm deep, aerodynamic carbon rim, optimizing airflow for reduced drag and enhanced stability. Its 22mm internal width supports wider tires, maximizing grip and minimizing rolling resistance. The wheelset’s tubeless-ready design allows for lower tire pressures. Paired with robust disc-specific hubs and a stiff spoke pattern, it ensures efficient power transfer and reliable braking performance.

ADAPTABLE COCKPIT

The cockpit features semi-integrated cable routing for a clean, aerodynamic look while maintaining easy access for servicing. A carbon handlebar with an ergonomic flat-top shape provides comfort and control. The frame is also compatible with both round and aero seatposts, giving riders flexibility when dialing in their ideal fit and performance setup. The result is a sleek cockpit engineered for uncompromised performance.
