Gallium CS Disc (INT) Shimano Ultegra
Argon 18
Race
Gallium CS Disc (INT) Shimano Ultegra is a carbon race road bike (2022), from Argon 18, part of the Gallium Cs family. It is a strong match for riders who want a sporty road feel without a full race fit, leaning toward a sporty riding position, while being best matched to paved roads. Its profile is strongest in areas like strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and a balanced aero profile for mixed road priorities. The main trade-off is a firmer ride feel than comfort-first options and more of a flat-to-rolling terrain bias than a climbing focus.
