Arktos 29/27.5 170F/150R
29/27.5" // 170mm Front/150MM Rear // Complete Carbon Frame // Fox Factory Front and Rear
The all-new long-travel Arktos 29-27.5 is ready to attack the roughest terrain. Combining 170mm of front travel with 150mm of rear travel, the mixed wheels provide the confidence at speed of a 29er with the handling characteristics and maneuverability of a 27.5-inch bike. The design features dual water-bottle mounts, super-low standover and updated geometry.

What Size is Best for Me?
With low standover heights, we now have three sizes catered to your individual riding style. Pick the shorter reach and smaller wheelbase model for more maneuverability and quicker handling, or pick a larger size for more stability and a roomier ride.

Frameset Features
Exclusive Patented Sine Suspension System
The Arktos is a one-of-a-kind, do-it-all suspension bike designed to tackle any type of terrain. The heart of the Arktos is Alchemy’s patented dual-linkage platform called Sine Suspension. Sine provides next-level performance, and allows the bike to tear up climbs yet descend the roughest terrain with ease.
Fully Triangulated Rear Swingarm
Modern trail bikes are now being ridden on World Cup DH-level terrain and the requirements for frame stiffness are increasing every year. Thankfully the Arktos is one of the most laterally stiff bikes ever produced. With a fully-triangulated rear swingarm, oversize suspension pivots and compact linkage, the Arktos by design is made to handle anything you can throw at it.
The Details
They say the devil is in the details, and there’s no doubt we focused on the minutiae with the new Arktos. The bike features internal cable routing, dual-water bottle mounts, direct-mount chain guide, low standover and modern geometry. Each Arktos frame is also convertible to any travel configuration and the two longer-travel models can either run full 29 or a mixed-wheel mullet set up..
