Ultra-efficient
The frame is engineered with the highest stiffness-to-weight-ratio of any hardtail mountain bike in its class, which translates to ultra-efficient pedaling power and precise handling on the trail.
Custom compliance
Each frame is custom-tuned based on its size. Individual composite lay-up schedules are created to optimize vertical compliance to produce a smoother ride quality on XC terrain.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
