Alchemy's All-New Arktos - One Frame for Three Travel Options with 29-inch and Mixed-Wheel Sizes 1

Alchemy makes one platform take on a lot of jobs!

Alchemy Bikes, known for their exclusive patented Sine Suspension system, introduces their new carbon Arktos mountain bike. The Arktos is designed to allow for three travel configurations and two wheel sizes (29-inch and mixed-wheel “mullet” 29-/27.5-inch compatibility) with one frame. It also features modernized geometry with low standover to improve maneuverability and utilizes dual water-bottle mounts to support those long days in the saddle.

Alchemy Bikes’ philosophy is based on the relentless pursuit of perfection. The new Arktos has followed that path. “This bike has been in development for over two years,” says Alchemy founder, Ryan Cannizzaro. “With multiple travel and wheel size options, the Arktos is truly one of the most versatile mountain bikes ever produced.”

Alchemy’s Patented Sine Full-Suspension System

The new Arktos features famed designer David Earle’s patented dual-linkage suspension platform called “Sine”(deriving from the shock rate, which resembles a sine wave when graphed). The design creates suspension that is regressive through the first part of the travel to absorb small bumps and provide climbing traction. It is progressive in the middle to avoid wallowing on big hits or in hard, fast corners, and is regressive again in the last 15 percent of the stroke so the bike can use all of its rear-wheel travel.

“We have made big improvements to the new Arktos, culminating in what we feel is one of the best riding mountain bikes to date,” said Alchemy Engineer Matt Maczuzak. “We are now on our 3rd refinement of our patented Sine Suspension system and the ride-quality for both climbing and descending continues to improve. Alchemy racers, Evan Geankoplis and Todd Renwick will be competing on the Arktos in 2021. From professional racers to enthusiasts, we think you’re going to love this ride.”
