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.
