The Argon 18 Sum Shimano Ultegra Di2 delivers aerodynamic performance with precise electronic shifting. Built on the same haunched aero frame as other Sum models, it features sculpted tubing, hourglass headtube, and compliance-balanced design.

Internal routing and integration keep the design sleek and drag minimal. It’s an ideal option for riders who want strong component performance in a refined aero package.
