From rough race days to the unknown, the Dark Matter is your ultimate gravel machine. With massive tire clearance, smart storage, and rugged geometry, it powers through any terrain. 

Whatever the ride throws at you—get over it.
Gravel throws unique challenges at riders, therefore it demands unique frame characteristics.  gravel geometry draws on Argons endurance geometry, which derives directly from Argons 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.
ize-specific geometries to provide optimal performance and positioning for all riders
Argon 18's fit system offers size-specific geometries to provide optimal performance and positioning for all sizes, guaranteeing no rider left behind.

Our smallest bike frames offer the same ride feel as our largest frames. In fact, our XL frames have exceptional stiffness without excess weight, to avoid the 'dead' feel found in some larger frames. XS and XXS retain their inherent lightweight qualities, but without excess stiffness, avoiding harsh ride quality.

Great purchase
Material Type: Recycled Polyester, Color: Dark Navy, Size: X-Large
Purchased several shirts, all were great quality. You never know what you’ll get when you purchase sight unseen, these are worth it. Great value, style, and comfort. Color is exactly what you see online. True to size.

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
