Built with a lightweight alloy frame and advanced features, this bike is ready to handle anything from rough terrain to long bikepacking journeys.
Built for AdventureThe Grey Matter is designed to thrive on gravel roads, old logging trails, and muddy singletrack.

Whether you’re bikepacking, gravel racing, or just getting lost for fun, the Grey Matter is up for the challenge.
With rack and fender mounts, up to six bottle/utility mounts depending on size, and Argon 18’s Topological Compliance System (TCS) for vertical compliance and road vibration dampening, this bike ensures comfort, control, and performance.
