In The Relentless Pursuit Of Speed
Introducing the all-new Helios A—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 bike—it’s your competitive edge.
It’s light
Weight is a decisive criteria when it comes to justifying the quality of a top-of-the-range road bike. Saving a few grams on a frame while retaining its stiffness and quality presents a real challenge. Our engineers have taken up this challenge by redesigning the ACX carbon construction of our frame and fork to achieve a fantastic result, saving almost 300 grams on its frame.
Superior Power Transfer
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.
From racing admiration to engineering the ultimate aerodynamic machine
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.
This is 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 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.
It’s innovative
The complete series features a new semi-integrated carbon cockpit—handlebar, stem, and wheels—designed 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.
