Own the season: the Sum will get you ahead on the climbs, keep you there on the flats, and power you through the sprints.
All Together Faster
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.

Q&A - The Maloja Pushbikers' Sum, not your ordinary team bike design
Q&A - The Maloja Pushbikers' Sum, not your ordinary team bike design
The Maloja Pushbikers will be riding the Argon 18 Sum for 2024, as we kick off our three-year partnership with the UCI Continental team. The Pushbikers are well known for their unique and flamboyant personalities (and kits), so it was quite the design challenge to create custom artwork that lived up to that reputation. We spoke with Argon 18 graphic artists Sam Clairoux and Kim Sivert about the design process.
