Argon18 Anti Matter - Sram Force XPLR AXS E1

Built for speed where the road ends, the Argon 18 Anti Matter is a gravel race machine engineered without compromise. Designed around the demands of modern gravel racing, the Anti Matter blends aerodynamic efficiency, lightweight performance, and technical capability into one of the fastest gravel platforms available today.

At the front of the bike sits the ATTEN CHB-01 Aero Handlebar, developed with a relentless focus on aerodynamic performance and rider ergonomics. With integrated cable routing, an integrated computer mount, ultra-lightweight construction, and confidence-inspiring handling, every surface has been refined for real-world speed gains where aerodynamics matter most.

The frameset itself combines aggressive gravel race geometry with clearance for up to 55mm tyres, delivering high-speed stability while maintaining responsive handling on technical terrain. Internal cable integration keeps the bike clean and aerodynamic, while the included ATTEN x Apidura frame bag provides integrated storage for long race days and adventure riding alike.

Rolling on the highly capable Zipp 303 XPLR S wheelset, the Anti Matter benefits from a wide hookless tubeless profile designed specifically for modern gravel tyres. Paired with Schwalbe G-One RS PRO 700x45c tyres, the setup maximises aerodynamic efficiency, traction, and rolling speed across mixed terrain.

Drivetrain performance comes courtesy of the latest SRAM Force XPLR AXS E1 wireless groupset, combined with a SRAM Red 1 PM E1 XPLR Aero crankset and SRAM Red XPLR 10-46T cassette for wide-range performance without compromise. CeramicSpeed upgrades feature throughout, including the SLT headset bearings and T47 BB Alpha bottom bracket, ensuring maximum efficiency and durability.

Finished with premium components including the Repente Quasar 2.0 saddle, Ciclovation Leather Touch bar tape, and the dedicated Argon 18 Anti Matter Aero seatpost, this build is designed for riders chasing podiums, pushing limits, and demanding speed everywhere they ride.
