Planted And Responsive

A rider-focused design gives the Sum a ride that feels grounded and precise at speed.

The Topological Compliance System takes the sting out of rough roads while keeping the frame stiff.

Hourglass-shaped headtube on the Argon 18 Sum

Hourglass-Shaped Headtube

The hourglass headtube and draft-deflecting fork blades clean up airflow at the front of the bike.

The 3D System gives a wide fit window without compromising steerer stiffness.

D-shaped seatpost and integrated clamp on the Argon 18 Sum

D-Shaped Seatpost

A D-shaped seatpost with an integrated clamp keeps the rear end tidy and aerodynamic.

It pairs with the aero-profile downtube to cut drag without adding weight.
