Key Features
Carbon C Frame – A minimal weight gain of approximately 250 - 280 grams (0.6 lbs) for the C frame over the CC due to the different grade of carbon used.

Travel – 160mm Front / 150mm Rear
Wheel Size – Sizes S-XL: Mixed Wheel (29" Front / 27.5" Rear), Size XS: 27.5"

Used For
Trail Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike. Enduro If you’re looking for maximum performance while flying down heavier trails, an enduro bike is for you. These bikes combine ample suspension travel (typically 150mm+) with descent-focused frame geometry and components that allow for reasonably efficient pedaling.
