Polygon Helios A0 AXS Road Bike Highlight

Features

Ultra-Lightweight 800g ACX Carbon Frame

The HELIOS A features a UCI-Approved ACX carbon layup, weighing a mere 800g. Engineered for competitive road racing, the frame utilizes truncated airfoil tube profiles to deliver a 31% reduction in drag compared to previous generations, ensuring you cut through the wind without the weight penalty of traditional aero bikes.
Aerospace-Inspired Truncated Airfoil Profiles

The HELIOS A taps into aerospace engineering by shaping the down tube, seatpost, and head tube into truncated airfoils. This design provides the aerodynamic efficiency of a full teardrop profile while remaining stable in unpredictable crosswinds and significantly lighter.
34mm Tyre Clearance

The HELIOS A has clearance for up to 34mm tyres. Running wider tyres at lower pressures increases your contact patch and lowers rolling resistance, providing a smoother, faster experience on rough or imperfect roads.
LINC Semi-Integrated Carbon Cockpit

The LINC component line offers the perfect middle ground: the aerodynamic gains of internal routing with the mechanical adjustability of a semi-integrated handlebar and stem. The frame is also versatile and is dual seatpost compatible. Use the included aero seatpost for racing or a standard 27.2mm round post (via adapter) for training and endurance rides.
