The all-new Helios A — faster and lighter
The all-new Helios A is a UCI-approved carbon aero road bike designed for maximum speed and performance. Developed with the UCI Continental team TSG, the new Helios is 5.2 seconds faster and 150g lighter than the previous generation — the perfect balance of aerodynamics and climbing ability.
Versions in the Helios A range: HELIOS A0 AXS · HELIOS A9 Di2 Power · HELIOS A9 Di2 · HELIOS A8 Di2 Power · HELIOS A8 Di2 · HELIOS A7 Di2
Key features
Aerospace-inspired aero tubes
Down tube, seatpost and head tube use truncated airfoil shapes — the aero efficiency of a teardrop while staying stable when pedalling.
34mm tyre clearance
Fits tyres up to 34mm; wider tyres at lower pressure increase the contact patch and reduce rolling resistance — smoother and faster on rough roads.
LINC semi-integrated carbon cockpit
Aerodynamic fully internal cable routing that is still as easy to adjust as a separate bar and stem.
