Bike Builder
Handmade in Denver Colorado
With a heritage like Alchemy’s, it should come as no surprise to see a bike like the US-made Arkti come to fruition. Alchemy has been producing masterful titanium frames since the company was founded over ten years ago. But the Arkti is something special even for a company that prides itself for its titanium. It’s a Swiss Army Knife of a bike, able to switch between 29er and 27.5 plus tires and capable of aggressive trail riding or hitting that jump line you’ve been considering. The Arkti used Alchemy’s proprietary titanium tubing that promises a smooth but compliant ride and a durable finish that will look ace for years to come. It’s the once-in-a-lifetime bike that everyone needs to have in their lives.
Frameset Features
Beautifully Handmade with 3/2.5 Ti Tubes
Titanium is without a doubt the ultimate material for a hardtail, but the Arkti is something special even in the category. Alchemy created its own proprietary US-made 3/2.5 titanium tube set, which has been masterfully welded into one of the best riding off road bikes available. The Colorado-made frame has shaped seat stays and a varying thickness top tube to provide rider comfort and a flared downtube to provide bottom bracket stiffness.

We Make It, You Win
The Arkti is made in Denver, Colorado, which allows customers like you full access to a suite of manufacturing and paint capabilities. Want an Arkti with slacker head angle? Can do. Custom geometry options are available. Want an Arkti painted with the colors of the Colorado flag? No problem. Alchemy offers all of the same options as our Colorado-made road bikes with the new Arkti.
A League of Its Own
If you take a close look at the Arktii, you will see the details that put it ahead of the competition. Not only has the geometry been optimized for a modern trail-bike hardtail, but the oversize top and down tubes, the unique tube profiles at the head tube and bottom bracket, the proprietary shapes… all of these features create a comfortable ride that is compliant and responsive, fast and capable. It’s the once-in-a-lifetime bike that everyone needs to have in their lives.
