Argon 18 Dark Matter (MY26) GRX 822

At TCR Bike Shop our philosophy is “Fit before you Buy”

We may not have the most bikes on the floor because the majority of the bikes we sell are ordered to spec. Every cyclist is unique that is why we order the right bike for you.

Any time you purchase a bike from TCR we will run you through our bike fit process. This way there is no question of what size of frame you need. We will dial in your bar width and stem length and help you choose the perfect saddle. You can schedule your fit and we can help you find the perfect unique bike for you!

Most of this stock is available from our supplier and can arrive within 10 to 14 business days.

Product Overview

The redesigned Dark Matter embraces the wild side of gravel. It is engineered for long-haul comfort, grueling backcountry exploration, and technical, chunkier terrain—all while maintaining a nimble, road-inspired soul.

This completely reimagined carbon gravel platform blurs the line between fast gravel grinder and rugged backwoods explorer.

Unlike aero-first racing rigs, the Dark Matter focuses heavily on Topological Compliance, absorbing punishing vibrations while offering massive, category-leading clearance for true mountain-bike-sized rubber. Equipped with generous storage and a stable, confidence-inspiring geometry, it is the perfect machine for everything from singletrack cut-throughs to multi-day bikepacking epics.
