Canadian bike firm Argon 18 has released its multi-purpose Sum bike, which is claimed to be ‘light, fast and designed to keep you on the road all day.’
The company adds that the new Sum is ‘the bike for the classics, the crits, the climbs – and any challenge in between.’
Citing computational fluid dynamics (CFD) Argon 18 reports that the Sum’s aero performance is equivalent to its aero Nitrogen bike and is 9% faster than the Gallium Pro Disc.
CFD-optimization has been introduced to ‘maximize aero shapes while stripping unnecessary weight.’ The downtube, toptube and chainstays are optimized for a ratio of size, material thickness and aerodynamics. The hourglass-shaped headtube provides low drag while being rigid and lightweight.
Design details like dropped seatstays and an indented seattube help to keep the rider rooted in the saddle.
There is a non-proprietary cockpit, and the company’s included an updated 3D system for the widest fit window with easy adjustment and maximum stiffness. The Sum also features generous tyre clearance (30c).
With the launch of the Sum at the top of the company’s road race category, the Argon 18 line-up sees a refresh – as the classic Gallium Pro and Gallium are retired, as well as the aero Nitrogen. The Sum line will feature two models, the Sum Pro and the Sum, as framesets and with SRAM Force AXS and SRAM Rival AXS builds. Both models will be available globally in late 2022.
To celebrate the new addition to its line-up, Argon 18 welcomed UCI ProTeam Novo Nordisk into the family in January 2022, with a fleet of custom painted Sum Pros. Team Novo Nordisk is a UCI ProTeam founded in 2008.
