When You Combine Nitrogen and Gallium

Why We Love It
The Argon 18 Sum combines the aerodynamic advantages of the Nitrogen with the pure road performance of the Gallium Pro to solve the age old question: "Do I want a lightweight climbing bike or a slippery fast aero bike?" Combine the sum of both into one high performance package. Argon 18 dropped the seat stays and strategically designed the seat tube to deliver welcomed rider comfort to a category often known for a rigid ride. From chasing KOMS, crushing crits, or riding centuries, the Argon 18 Sum is ready for action.
