Sine Suspension 140mm travel, 29″, Arktos 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 29 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 29 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 29 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.

Maximize your suspension’s performance with BikeCo Pro Tunes

BikeCo offers proprietary Pro Tune services on the majority of Fox forks and rear shocks.

Fox Suspension is the pinnacle of performance, reliability, and longevity in our industry. Stock Fox suspension comes out of the box with a fairly aggressive tune – which is terrific for powerful, strong, aggressive riders with high ground speeds. Sounds like their World Cup DH and Enduro riders, right?

Pro Tune services calibrate the incredible performance of Fox suspension into a narrower band personalized to your riding specifics.

Utilizing a combination of proprietary lube oils, improved upper to lower fork fit, shim stack configuration, updated oil flow, unmatched bleed quality, and a few other trade secrets BikeCo Pro Tunes improve tracking, small bump compliance, minimize brake dive, run cooler (equating to more predictable performance from top to bottom of your descent), operates comfortably in a wide range of temperature (we test from freezing to 100 degrees), improves oil circulation, extends service intervals and more.

The most important advantage of Pro Tune suspension? Whether you are new to the sport or an experienced pro: suspension that works will let you ride more confidently. You will ride faster and have more fun with BikeCo Pro Tune Suspension.

To ensure that your suspension is dialed in our staff will review your riding experience, aspirations, ground speeds, size (height and weight) as well as specific chassis. BikeCo stands behind our Pro Tune service with a 30 day retune service if you feel that your particular riding requires a shift in tuning. BikeCo also offers discounted disposition retunes as your skillset progress if required.

After the Pro Tune your suspension only requires standard levels of maintenance in the future. To maintain the best performance BikeCo recommends sending the suspension in (we use proprietary lube oils, have specific bleed techniques, etc) although standard Fox oils can be used. Standard lubes will compromise some of the finite tune but with the other Pro Tune modifications a standard lube shock will still out perform stock.
