Experience the thrill of conquering steep drops, navigating blind lines, and tearing through chunky singletrack riddled with roots and rocks with ease. The fierce Giant Reign 29er mountain bike is equipped with smooth suspension and confident handling, giving you the power to tame even the wildest enduro terrain. Don't settle for mediocrity - take on the challenge and ride like a pro with our top-of-the-line mountain bike.

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

A strong and durable ALUUX SL aluminum 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.

The most accurate way to determine any bike’s weight is to have your local Bicycle Warehouse 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.
