Introducing the all-new Helios Athe pinnacle of aerodynamic engineering and racing performance. Developed over three years of relentless testing and perfected with the elite UCI Continental Team, TSG, the Helios A is built to dominate any race condition.Refined to be 5.2 seconds faster than its predecessor and lighter than ever, the Helios A is meticulously optimized for speed, agility, and control. Whether battling headwinds or slicing through tight corners, its cutting-edge aerodynamics and balanced stiffness deliver an unmatched ride.This isnt just a bikeits your competitive edge.

It’s Light:

Weight is a key factor in proving a high-end road bikes quality. Our engineers tackled the challenge of trimming grams without sacrificing stiffnessredesigning the ACX carbon frame to shed nearly 150 grams while maintaining top performance.

Superior Power Transfer:

Weve reinforced the bottom bracket for instant power transfer and adopted a T47 threaded system for added stiffness, smooth pedaling, and zero creakswhile up front, a shortened, reinforced head tube sharpens cornering for a decisive edge in every sprint

Aerodynamic:

The downtube, as the bikes aerodynamic core, now features dual bottle cage mounting positionslow for large bottles, high for smaller onesto reduce drag across setups. Paired with a newly redesigned, sleeker fork, the Helios A now cuts through air more efficiently than ever.

Performance Perfected:

With the new Helios A, Polygon redefines adaptability in road biking. The frame supports both an aero seat post (included) and a 27.2mm round option for added comfortgiving riders full control, whether tackling fast sprints or rough courses. It also fits tires from 28c to 34c, making it ultra-versatile for varying road conditions, and comes equipped with a 45mm carbon rim for balanced performance across the series.

Innovative:

The complete series features a new semi-integrated carbon cockpithandlebar, stem, and wheelsdesigned by us and proudly branded under our new component line, LINC. Built to balance performance and comfort, LINC wheels make the bike lighter, faster, and more stable in crosswinds, while maximizing speed on flats. Ideal for modern cyclists who value both performance and elegance.
