Push beyond the pavement with the Argon 18 Dark Matter GRX, a gravel bike that thrives where the tarmac ends. Designed for performance, durability, and versatility, this adventure-ready machine is built to conquer unpredictable trails, endless dirt roads, and everything in between — all without compromising speed or comfort.
Key Features:
- Trail-ready tires for any surface: The Vittoria Terreno T50 Mixed 700x50c tires are your go-anywhere companions — combining directional grooves with aggressive grip knobs for confidence across gravel, dirt, and muddy conditions.
- Endurance at its core: With nylon-reinforced sidewalls and an adaptable endurance casing, these tires don’t just roll smoothly — they last, mile after rugged mile.
- Built for the long haul: The DT Swiss G1800 wheels offer a rock-solid ride feel thanks to their wide rims, sturdy spokes, and a reliable ratchet hub. Whether you’re chasing gravel KOMs or heading deep into the backcountry, they’ve got your back.
- Shifting that won’t quit: The Shimano GRX RX822 12-speed drivetrain (up to 51T) delivers smooth, quiet, and reliable shifts even on punishing climbs — and the chain stabilizer’s ON/OFF switch makes maintenance a breeze.
- Balanced geometry for rough terrain: The Dark Matter frame is engineered for off-road stability, without sacrificing the reactivity Argon 18 is known for.
