The Alchemy Arktos is a versatile and playful, mid-long travel 27.5” brawler that is loaded with features. Full internal cable routing and a direct mount chain guard come stock on alchemy’s premium carbon fiber frame. A fully triangulated rear swingarm boosts lateral stability, making the Arktos super stable, yet playful with the short chainstays and the 27.5” wheels. 150mmm of Alchemy’s Sine Suspension system, which uses a dual-linkage design and unique suspension kinematics, supplies a plush first half of travel for small bump compliance, a progressive mid-stroke for good pedaling efficiency, and a seemingly bottomless last part of travel to protect against big hits. The Arktos is a blend between the most playful trail bike you’ve ever ridden and a plush long-travel enduro beast, sporting a 65.5-degree headtube angle paired with a 73.5 seat tube angle.
This Jenson USA Exclusive Build comes with a SRAM NX/GX Eagle 12-speed drivetrain. This includes a cassette that has a hill-crushing 11-50T gear range that makes climbing and pedaling through rough terrain a breeze. Magura MT5 HC hydraulic disc brakes provide excellent stopping power so you can descend under control. E*Thirteen TRS Alloy Boost Wheels are paired with Kenda Hellkat tires that can be set up tubeless for a smoother ride, better traction, and fewer flats. With the PNW Rainier Solo Dropper Post, you'll be able to quickly lift and lower your saddle with the press of a lever.
