The emerging crop of mixed-wheel bikes have been described as mullet bikes, so the above is certainly appropriate. But there is more to the new Alchemy NINE7FIVE than just humorous sloganeering: this bike is a serious enduro weapon. With the bigger front wheel, the bike has the ability to mow over any obstacle. And with the smaller rear wheel, it provides the quick handling of a playful 27.5 ride. It’s really the best of both worlds.



Arktos 29ST

CARBON // 29" // 120MM REAR // 140MM FRONT

The Arktos 29ST (for short travel) is the younger brother of the Arktos 29, and like younger siblings, it’s shorter, quicker and more playful than its elders. Where the Arktos 29 was designed to crush fast, open, super techy EWS tracks, the Arktos 29ST is capable of hitting the same bone-tingling descents, but adds a little fun in the mix. It turns quicker and changes directions faster on those tight switchbacks, but still has that slack geometry to keep it stable at speeds. It’s the everyday bike for hitting every track.

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.

To celebrate 10 years making bikes and 5 years developing the Arktos we designed the Arktos 27.5LE (Limited Edition). The 10-year anniversary Helios and Arktos 27.5LE are an embodiment of our design process – no shortcuts. Every detail is hand painted on the Arktos 27.5LE and the frame is clear coated with metallic pearl flake to give it added flare.

Ti // 29" // 120MM FRONT

With a heritage like Alchemy’s, it should come as no surprise to see a bike like the US-made Ark Ti come to fruition. Alchemy has been producing masterful titanium frames since the company was founded over ten years ago. But the Ark Ti is something special even for a company that prides itself for its titanium. It’s a Swiss Army Knife of a bike, able to switch between 29er and 27.5 plus tires and capable of aggressive trail riding or hitting that jump line you’ve been considering. The Ark Ti used Alchemy’s proprietary titanium tubing that promises a smooth but compliant ride and a durable finish that will look ace for years to come. It’s the once-in-a-lifetime bike that everyone needs to have in their lives.
