The Argon 18 Dark Matter GRX Bike is built for riders who take gravel seriously — not as a weekend novelty, but as a discipline that demands its own geometry, its own carrying capacity, and its own kind of confidence. Argon 18 has a long history of building performance road and triathlon bikes, and the Dark Matter applies that same engineering rigor to terrain that rarely follows a plan.

The carbon frame is shaped around an adventure-first geometry — a taller head tube, considered fork rake, and a longer wheelbase than you'd find on a race-oriented gravel build. On loose descents or unfamiliar tracks, the handling stays planted and predictable, the kind of stability that actually matters when you're far from a trailhead and the surface underneath you keeps changing. Clearance for 700×57mm tires gives you genuine flexibility across surface types, from compacted gravel to rougher backcountry two-track, without compromising the frame's responsiveness when you want to push the pace.

What distinguishes the Dark Matter in a crowded carbon gravel field is its integrated in-frame storage system. Compartments built into the frame itself — combined with an extensive network of mounting points across the fork and frame — mean you can carry tools, spares, layers, and nutrition without strapping on aftermarket bags that upset the bike's balance or aerodynamics. The Shimano GRX drivetrain rounds things out: a gravel-specific groupset designed for mixed-terrain shifting, reliable under load, and tuned for the kind of wide-range gearing that long days in the dirt actually require.

Design Benefits

  1. Adventure Geometry That Earns Your Trust: The Dark Matter's longer wheelbase and taller front end create handling that feels deliberate rather than nervous on loose or unpredictable surfaces. When you're three hours into an unfamiliar route, that composure isn't a luxury — it's what keeps you riding confidently rather than managing the bike.
  2. Serious Tire Clearance for Real Terrain: Support for up to 700×57mm tires means the Dark Matter isn't limited to hardpack gravel. Wider rubber absorbs rougher surfaces, improves traction in soft or wet conditions, and opens up routes that narrower gravel bikes simply can't handle. The frame is designed to accommodate that range without sacrificing stiffness or pedaling efficiency.
  3. Integrated Storage That Changes How You Pack: Most gravel bikes force you to choose between external bags and a clean setup. The Dark Matter's built-in frame storage resolves that tension — compartments designed into the frame keep essentials close and the weight centered, so the bike handles consistently whether you're loaded for a long day out or running light on a fast loop.
  4. Shimano GRX Drivetrain Built for Mixed Conditions: GRX isn't road components adapted for gravel — it's a groupset developed specifically for it. The lever shape, the derailleur geometry, and the gear range are all calibrated for the kind of varied terrain the Dark Matter is designed to cover. Shifting stays positive and predictable even when conditions get rough or the chain is under load on a steep climb.
  5. Mounting Versatility for Every Configuration: An extensive set of frame and fork mounting points means the Dark Matter adapts to how you actually ride — whether that's a minimalist setup with just a couple of cages, or a fully loaded configuration with racks and bags for multi-day routes. The bike was designed to carry gear without being defined by it.

Final Take

The Dark Matter is for the rider who wants a carbon gravel bike that doesn't ask them to choose between performance and capability — one that handles technical terrain with assurance, carries what you need without compromise, and runs a drivetrain purpose-built for the discipline. If your rides regularly take you far from pavement and you want a bike that was designed with that reality in mind, the Dark Matter is a considered choice.

Fun, enticing dog toy. As stated in description it won’t hold up for aggressive chewers
Color: Blue
Rating this based on description. My dog loved this toy. It was smaller than I had pictured in my head, but that was on me. I did read the description ahead of time, which clearly states this is not for aggressive chewers. My dog is trained not to rip toys apart so I wanted to give this a shot, but i guess just her jaw strength and teeth were too much. She carried it everywhere. I turned it on periodically. The movements are small, but enough for her to be captivated with the toy. It did mostly survive for about a day before I needed to take it away due to the Velcro opening. Once it started to pull apart she did chew a piece of the Velcro off. It might be helpful with a flap over design covering the Velcro. I have a singing Santa decoration like this where the Velcro is covered up and I have to pull it back a little to get to the Velcro opening. The gaps on the sides of the closure are a bit to large making it tempt my dog to pull and open it up. I wish there was a more durable option that could hold up to aggressive chewers, but this product was clear about that in the description. I think the opening to the batteries could use some improvement. Granted I do not have the perfect answer to fix this, but I am also not a toy designer.

A Toy Ball for All Seasons!
Style: Small Ball, Size: 1 Count, Style: Small Ball, Size: 1 Count
Oh my gosh! I’m so happy to find the almost exact ball my 5 1/2 pound 9 month old Morkie, Charlie, that mommy lost at the campgrounds! It was his favorite toy and although he has others, he loved this one above all others, so to find another one was an answer to my prayers. The difference is so minor and in a good way. It is very durable as Charlie has very sharp teeth, but this one is just a bit softer making it easier to hang on to playing fetch. But for Charlie, the size is the same, the squeekiness is the same, the color is the same (yes they can see some colors) and he went into a jumping frenzy when I took it out of the package and the price was unbelievably inexpensive for such a high quality toy! Thank you! Thank you! Thank you! Good mommy! ( I’m ordering another one as a back up, jic!)

Great investment.
Style: Small Ball, Size: 2 Count
Dogs love them. Durable. Chew worthy for a beagle and a German shepherd. You cannot smell the flavor imparted but the pups definitely can. Always purchase the amount you need so each dog can have one. .

Bacon and a Ball? Can life get any better?
Style: Small Ball, Size: 3 Count
Come on.. these balls are the best. They smell like bacon, yes, they really do. They are durable and squeak. Upon aggressive play, the squeak will die out but the ball will still be useable.

She LOVES this ball
Style: Small Ball, Size: 1 Count
Our dog likes toys, but this ball is now her favorite ball. She even took it to bed with her last night. Our dog is 65 pounds, but she likes smaller toys so I ordered the small ball. It’s a good size. It’s nice and soft and squeaks. She seems to kills the squeaker right away, but she didn’t with this ball. It seems to be the least amount of money I’ve spent on a toy for her and it’s her favorite. I ordered another one just to have on hand. This toy is a great bargain!
