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.
It will truly transform your ride.
Exclusive Patented Sine Suspension System
The Arktos is a one-of-a-kind, do-it-all full-suspension bike designed to climb and descend with the same aplomb. The Arktos features a patented dual-linkage platform called the Sine Suspension, which was designed by suspension guru David Earle. The Sine name is derived from the way the shock rate, when graphed, resembles a sine wave. With Sine, there is regression through the first part of the travel to absorb small bumps and provide climbing traction, progression in the middle of the stroke to avoid wallowing on big hits or in hard, fast corners, and then slight regression again at end stroke to enable full use of rear wheel travel. Sine is also designed to minimize chainstay growth to improve pedaling efficiency and keep the suspension active under braking.
Modern trail bikes today are being ridden on terrain that only a DH bike would have tackled a few years ago. As a result, the requirements for frame stiffness are increasing every year. Luckily if you are riding an Arktos, you are riding one of the laterally stiffest bikes ever produced, and one of the big reasons for this is the full triangulated rear swingarm. The Arktos by design is made to handle all you can throw at it.
They say the devil is in the details, and there’s not doubt we focused on the minutia with the Arktos 29. The bike features details like internal cable routing and a direct mount chain guide, as well as every bike features Fox Factory suspension both front and rear. The rear shock has been specially tuned for Alchemy to provide the best in pedaling efficiency and downhill performance and all of the bikes are using stiff and light Fox 36 forks.
