Weight
The 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.
Ultra-efficient
Advanced composite frameset is 241g lighter than previous generation. The bottom bracket area is stiffer for faster acceleration, and a steeper seat tube puts the rider in an efficient climbing position.
Superior control
FlexPoint Pro suspension delivers 100mm of smooth, active rear travel. The frameset features modern XC geometry including a slacker 67.5-degree head tube and 110mm suspension fork for technical descents.
29er stability and speed
Frame geometry and suspension are optimized for fast and stable 29-inch wheels. A longer reach and modified cockpit including a 35mm composite handlebar and alloy stem further boost balance and stability on XC terrain.
