Get rough and ready for anything with the new Grey Matter. The gravel-specific handling and features that made the Dark Matter the ultimate gravel machine is now available in an alloy frame.

Go On. Get Lost.
Really – go get lost. You’ve got extra snacks, gear, and you’ve got the bike that will go anywhere with you. Kicking up rocks on an old logging road? No problem. Muddy singletrack? Comes off easy. Grit pinging your frame for the next hundred miles? Didn’t notice. Get even further off the beaten path with a bikepacking-ready ride with fender and rack mounts, and up to six bottle and utility mounts, depending on size. Also with internal cable routing at the headset and external at chainstays, and our 3D headset with cable integration for easy maintenance and dialed-in fit options.

Ideal for
The self-sufficient gravel adventurer - also looking for peak performance.

Gravel throws unique challenges at riders, therefore it demands unique frame characteristics. Our gravel geometry draws on our endurance geometry, which derives directly from our performance road race series, meaning handling, responsiveness and race-ready positioning are paramount. Gravel and endurance both call for a longer wheelbase than a performance road bike, which you'll see on both the Krypton and Dark Matter. The Dark Matter features a higher bottom bracket and adjusted headtube angle and raked fork to adjust our hallmark precision handling to a wider tire size windows (up to 45C); both for ride quality and to avoid toe overlap on the twists and turns of more technical rides. Gravel geometry also features a slightly more upright position, providing a higher degree of comfort on rougher surfaces and long-haul routes.

We believe a good fit is the key to optimal performance. Argon 18’s proprietary 3D System is an integrated solution that extends the headtube for more flexible positioning options. Three headtube positions are possible for every frame size, increasing stiffness by 5% at 15mm and 11% at 25mm, versus traditional spacers. It allows also a larger fit windows (60mm of stack adjustment compared with 30 for a traditional setup). With this system, the handlebar height can be perfectly adjusted to meet the needs and preferences of every rider.

The Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning. Regardless of your build, gender or your riding style, our frames are designed so that your fit will always be efficient and comfortable, ensuring the ultimate in handling. We offer sizing from XXS to XL in all of our road bikes, and XS to XL in our Tri bikes, with each size approached individually from a design and performance perspective. While a lot of manufacturers optimise performance and weight targets for a medium size frame and simply scale up or down, we assess the performance of each size based on the individual character of that particular geometry. For example, even our largest frames have exceptional stiffness without excess weight, to avoid the 'dead' feel found in some XL frames. XS and XXS retain their inherent lightweight qualities, but without excess stiffness, avoiding harsh ride quality.
