What is my size?

Share

Stay cool when the trail gets rowdy. From big climbs to steep, rocky descents, this full-composite ripper was designed with Giant enduro pros for hard-charging confidence and control.

Key Performance Factors

Race-bred suspension

Maestro rear suspension developed and tested under extreme conditions of Enduro World Series races. The trunnion mount shock has a longer stroke and smoother feel, and the Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight.

Progressive enduro geometry

The purpose-built composite frameset helps you ride aggressive descents and rail corners with confidence. Enduro-optimized head and seattube angles, plus a 170mm fork with 44mm offset, produce confident front-end handling.

29er confidence and control

Larger 29-inch diameter wheels optimized to roll over rugged enduro terrain with improved balance and stability, giving you the momentum to crank up tough climbs and the confidence to fly on fast, technical descents.

  • 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.

Highlights

The geometry of the Advanced composite frame and swingarm was developed specifically around 29-inch wheels. That means shorter chainstays, a longer toptube, and just the right angles with the headtube (64.56 degrees) and seattube (76.36 degrees). We gave it an updated Maestro rear suspension system with 146mm of travel. The trunnion mount shock and Advanced Forged Composite rocker arm deliver an active, super plush feel on the trail.
