Handcrafted in Denver Colorado

The Hyas is your do-everything-quiver-killer bike. From muddy fire roads to high-speed mountain descents, this monster will chew up whatever you throw at it. The rear triangle is the same as our award-winning Aithon, giving the rider a stiff yet cushioned ride with the ability to run up to 40mm tires. Warning: Once you are on the Hyas, it’s going to be hard to get off it.

Frameset Features

// Alchemy’s Award-Winning Colorado-Build Carbon Construction

For the past decade, Alchemy carbon bikes have received accolades and acclaim from both magazine editors and riders alike. And it’s really no surprise. We’ve spent years perfecting a proprietary layup that provides a ride quality that is unrivaled in today’s carbon frames. Take a closer look at the tube junctions of an Atlas, and you will see just one example of our carbon mastery. Small bands of carbon intersect to create a precise pattern…it’s art with function, and the reason why Alchemy carbon frames continue to be the most sought-after bikes in the world.

// Shaped Top and Down Tube, Flares at BB and HT for Added Rigidity

Take a close look at an Hyas frame…do you see the unique profile of the top and down tube? Do you see the way the down tube flares, seamlessly flowing into the bottom bracket? These details of course help create the visually stunning look of an Alchemy bike, but there is also science behind the art. The proprietary shapes create a bike that is both stiff but comfortable, compliant yet responsive, fast and capable, yet easy to handle in the most demanding conditions. It’s the reason why Alchemy continues to earn accolades for making the best carbon bikes in the business.

// Carbon Dropouts for Flat-Mount Disc Brakes

From cutting to mitering to layup to curing to painting, each Atlas carbon frame is entirely made at our Denver, Colorado location. But it’s NOT just where it’s made that creates an award-winning bike, but how each frame is made. For example, take a closer look at the carbon dropouts on the Hyas frame. You will see where art and engineering collide to create a detail that is both functionally stout and aesthetically appealing.
