Details

From all day epics to technical singletrack, we've got you covered.

If you're looking for one bike that does it all, look no further than the Instinct. We've designed a bike that's capable of tackling technical trail riding but still allows you to push the pedals hard on the climbs. We've updated the geometry, frame features, and suspension kinematics to make sure you feel confident on the up's, down's, and everything in between. Trust your Instinct.

What sets the Instinct apart.

Total trail precision
Razor sharp handling and a buttery but efficient suspension setup means satisfying small bump compliance and addictive flickability. Hitting the sweet spot between big hit confidence and surgical levels of precision, it rewards the rider ready to ride more of everything, faster.

An Instinct for every rider
Embiggening or shrinking a frame isn't enough. That's why the Instinct comes in six distinctly sized frames with specific suspension kinematics and two wheel-size options. It's the only way to ensure every element of the Instinct's character gets fully realized for every rider.

The right setup for any trail
Total precision is yours on any trail with our RIDE-9 adjustment system and 2-position rear axle that allows for chainstay length adjustment. It's everything you need to quickly arrive on the best setup for the trail ahead.

- The most versatile platform in our range
- Perfect blend of climbing and DH performance
- Adjustable chainstay length to suit the rider
- Kinematics, fit & wheel size adjusted per size
