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-optimised 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 optimised 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.
