Arktos 29
Carbon // 29" // 160MM front // 140MM rear // Starting at $2999
Featuring Alchemy’s exclusive Sine full-suspension system
The Arktos features famed designer David Earle’s patented dual-linkage suspension platform called “Sine”. The name “Sine” derives 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, 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. It’s efficient, responsive, and provides downhill capabilities unparalleled in today’s crop of modern trail bikes.

What People Are Saying About Alchemy
"As of today, I'm officially a huge fan of Alchemy. The craftsmanship, quality, attention to detail, etc. of their custom bicycle frames seems to just be on another level." -Stephen
“I ordered a Arktos ST and I couldn’t be happier with it. The bike rides great. The fork and shock combination make the bike climb as well as any bike I’ve ridden. Fit and finish are as good as all the top high end brands I’ve looked at.” -Casey
"I have two Arktos’. Just took the new 29 on its maiden ride and I have to say I was more than surprised... it climbs like a goat and goes downhill like that same goat being chase by a lion. Mmmm...wow!" -Brian
