Sine Suspension 140mm travel, 29″

The Alchemy Arktos 29 is a a brand new bike from Alchemy and it is the ultimate trail weapon. With long travel 29ers becoming more popular and preferred for some riders, the Arktos 29 is one to add to your short list of bikes. The bike is playful and responsive while maintaining a controlled stable feel.

The Arktos 29 is a fun bike across a wide variety of trails due to it’s effective suspension system and geometry. Efficient while climbing, quick to put power down accelerating out of corners, and certainly competent in the steeps. With Alchemy’s Sine suspension the Arktos 29 is one of the best pedaling trail bikes that is capable of tackling the rowdiest of EWS descents.

Sine Suspension:

The Arktos features a dual-linkage platform called “Sine Suspension” that Alchemy licensed exclusively from David Earle. The name “Sine” comes from the shock rate, which resembles a sine wave when graphed. It’s regressive through the first part of the travel to absorb small bumps and provide climbing traction. In the middle of the stroke, its progressive to avoid wallowing on big hits or in hard, fast corners. Then it’s slightly regressive again in the last 15 percent of the stroke to enable the bike to use all 6 inches of its rear-wheel travel. With this bike you could talk technologies and physics all day long, but none of that stuff really matters the moment that you feel the efficiency, responsiveness and control the Arktos gives you on any terrain. It will truly transform what you thought you could do on the mountain.

By comparison the Sine Suspension rides a bit like a VPP, or Virtual Pivot Point, bike. The Arktos is poppy, quick and fun but has a more refined feel particularly early in the travel where it has better small bump compliance and tracking than a typical VPP.
