CUSTOM KIT OPTIONS
Alchemy Arktos 29 Frame Kit Options:
Fox Performance DPX2: Sharing design influence from the more aggressive X2 the DPX2 is designed as the ultimate trail shock. Three modes – Open, Medium & Firm – give riders options to personalize performance across a variety of terrain. The DPX2 tune and feel is a notable improvement compared to the previous Float X. It also offers better heat capacity over single chamber shocks.
BikeCo works with the Fox lineup for many reasons – in particular, they work awesome and are incredibly reliable for our clients. Since the Alchemy runs a 160mm Enduro fork let’s define some of the options available in the Fox Float 36 lineup.
There are four levels of Fox forks available, excluding OEM variations.
Rhythm & Performance (Grip Damper)
Performance Elite (HSC/LSC or Fit 4 Damper)
Factory (HSC/LSC or Fit 4 damper)
In this kit we offer the Performance Elite and Factory options.
Performance Elite has the same dampers as the Factory offerings without the Kashima coating (Performance has black stanchions).
Factory forks have the familiar Kashima coating on the stanchions for maximum performance and longevity.
HSC/LSC (RC2) Dampers offer external controls for high and low speed compression to fine tune your fork’s performance. Combine these controls with air pressure, volume spacing and rebound to setup your bike for any trail condition. Riding bigger, more aggressive, faster trails? Undeniably, this is your ideal damper.
Fit 4 Dampers feature a 3 mode compression switch – Open, Medium , Firm – and adjustable compression control in the Open setting. Fit 4 forks feature a more “trail” feel than their RC2 cousins while offering a quick “lockout” for riders who desire the firmest offering to climb the steepest / longest trails.
Looking for even more performance from your suspension?
At this point it’s time to Pro Tune your Fox fork and rear shock for the most personalized setup available. Flip to the Pro Tune tab for more info and to fill out your bio for our suspension techs.
This season the Fox Transfer post (Performance = black, Factory = Kashima coat) paired to the Wolf Tooth ReMote has been the absolute go-to setup. Great reliability, a variety of sizing options, incredible ergonomics in other words, it’s an easy choice.

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 5.5 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.

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.
