Argon18 SUM

Premium Performance for Passionate Cyclists

Decisions, decisions… made easy. With a bike that gives you flat-out advantage on the climbs, the sprints and the straightaways, the only decision you’ll need to make is how nice you want to be to the other guys.

A rider-oriented design approach ensures a frame that is both rooted and responsive, with a ride experience most aero frames can’t match. With a layup engineered to maximise aerodynamics while keeping weight low, the design process for the Sum allowed us to strip away all unnecessary weight within the new aero profile tube shapes - all while maintaining maximum power transfer.

Precision positioning
Argon18s performance road geometry prioritises the needs of racers: holding a low, aero position, having confident handling on technical courses and in bunch sprints, and highly efficient power transfer. These bikes often feature aero tube shapes or tube shapes designed for maximum stiffness at key areas, like the bottom bracket. A lower front end and longer top tube than Argon18s endurance geometry lets you achieve that aero position, and a narrower wheelbase provides the razor-sharp reflexes for those tight corners and quick handling in the bunch. Argon 18 bikes have a lower bottom bracket than most, which makes these bike exceptionally stable, and enhances their renowned ride quality.
