Polygon Helios A8X (Blue)

Introducing the all-new Helios A road bike—the 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 isn’t just a road bicycle—it’s your competitive edge.

Features

• Weight is a key factor in proving a high-end road bike’s quality. Our engineers tackled the challenge of trimming grams without sacrificing stiffness—redesigning the ACX carbon frame to shed nearly 150 grams while maintaining top performance.
• We’ve reinforced the bottom bracket for instant power transfer and adopted a T47 threaded system for added stiffness, smooth pedaling, and zero creaks—while up front, a shortened, reinforced head tube sharpens cornering for a decisive edge in every sprint.
• The downtube, as the bike’s aerodynamic core, now features dual bottle cage mounting positions—low for large bottles, high for smaller ones—to reduce drag across setups. Paired with a newly redesigned, sleeker fork, the Helios A now cuts through air more efficiently than ever.
• 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 comfort—giving 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.
