Au – Alchemy Ultralight: Gold Level Performance

Au – The chemical symbol for Gold – signifies the highest line of quality from our USA shop.

The Alchemy Ultralight line of road, gravel, and Ti MTBs is insanely lightweight (how does an 800g Large gravel frame sound?) and more stiff for a more responsive, race-ready ride.

This is handmade performance at its finest.

IT STARTS WITH THE FIT – fit included with every frame

Any dream bike starts with a custom fit, and Alchemy is proud to provide custom geometry on both Atlas & Ronin titanium and carbon frames.

Each Alchemy carbon frame utilizes a tube-to-tube construction followed by a unique overlaying design. This allows for a proper fit for everyone, regardless of height.

The same can be said for our hand-welded US-made titanium frames. We can design around your custom needs.

We have developed our patented SINE suspension system with the characteristics and kinematics to best counteract the effects of weight transfer on the suspension system, eliminating bobbing from pedaling, while retaining the maximum tune-ability for riders of various sizes.


The Flip Chip is a specially engineered spacer in the suspension linkage that can be rotated to alter the ARKTOS geometry for different riding styles. Adjust the head and seat tube angles by 3/4° with the turn of a bolt.

Any ARKTOS model can be easily converted into a different travel (or back again) in under 30 minutes, with one of Alchemy’s Conversion Kits, so you literally have two (or three!) bikes in one for a fraction of the cost.
