Arktos 29 ST
“Incredibly smooth and controlled” bike Magazine USA
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.

Frameset Features
Exclusive Patented Sine Suspension System
The backbone of the Arktos 29 ST is the Sine Suspension System. Sine is what makes the bike climb like a mountain goat and descend like a DH rig. The Sine name derives from the way the shock rate, when graphed, resembles a sine wave. With Sine, there is regression through the first part of the travel to absorb small bumps and provide climbing traction. In the middle of the travel, there is progression to avoid wallowing on big hits or in hard, fast corners. At the end, there is slight regression again to enable full use of rear wheel travel.
