From the bike park to enduro tracks to steep singletrack shredding, this all-mountain bruiser has swagger to spare. The lightweight, super-stiff aluminium frame is long and low, and its Maestro suspension helps you float through the rough stuff.This amped up version of the Reign enduro and all-mountain machine is made for riders who gravitate toward steep, rough and aggressive descents. It offers a longer travel 180mm fork and robust components that make it suitable for unforgiving terrain. The super strong and stiff ALUXX SL aluminium frame features updated geometry with a longer cockpit that’s designed to optimize its 27.5 wheels. The trunnion-mount Maestro rear suspension system offers 160mm of smooth, active travel and is bolstered by the new Advanced Forged Composite upper rocker arm, which is lighter and stronger than the previous aluminum design. If hammering through rock gardens and flying down steep descents is your idea of the perfect ride, then Reign SX is the machine for you.

27.5 agility and control

27.5-inch wheels balance agility and control, giving you the ability to roll over rugged terrain, flick the bike at speed, change lines, and explode out of corners.

Latest suspension tech

Updated Maestro rear suspension features a trunnion mount shock with a longer stroke and smoother feel. With 160mm of travel (and 170mm up front), it has the new Advanced Forged Composite upper rocker arm for increased stiffness and strength plus lower overall frame weight.

Enduro geometry

The lightweight and stiff Advanced-grade composite frameset features updated enduro-style geometry, so you can ride aggressive descents and rail corners with confidence.

Technologies

ALUXX SL Aluminium Technology

This High-Performance level, state-of-the-art aluminium material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for high-performance ride quality.

Advanced Forged Composite Technology

A state-of-the-art high-pressure moulding process is used to produce complex-shaped carbon fibre components that are lighter, stiffer and stronger than similar components made from aluminium. This technology is used in critical performance parts such as Maestro Suspension rocker links.

Maestro Suspension Technology

Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.

OverDrive

Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.

Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
