Product Info

It's time to wake up and smell the gravity. The Giant Reign SX Complete Mountain Bike is a big beefy enduro bike made to crush downhill descents on rugged terrain. An extra stiff aluminium frame gives the Reign SX the power to bang out tight corners while still being light enough for the uphills, and 180mm of travel in the fork gives it the cushion to gobble up bit hits with ease.

Product Details


ALUXX SL Aluminum ConstructionExtremely lightweight framesets featuring high-performance strength-to-weight ratios, predominantly featuring 6011 alloy. A heritage of craftsmanship combined with unmatched manufacturing capabilities gives Giant the unique ability to monitor every step of the aluminum frame-building process. Through Giant's cutting-edge materials science, proprietary forming techniques, and attention to detail, we are constantly advancing aluminum performance to create bikes that are lighter, stronger and stiffer. The difference can be felt in the ride. Every aluminum bike bearing the ALUXX Aluminum Technology label must live up to the highest standards and meet the tightest tolerances of any aluminum frame in the world.

OverDriveGiant’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.

Trunnion MountThe latest Giant off-road models feature updated Maestro Suspension systems with a new Trunnion Mount shock and Advanced Forged Composite rocker arm. The Trunnion Mount allows for a longer shock shaft, which produces a lower leverage ratio and smoother ride performance. It also allows for shorter chainstays to improve quickness and agility on the trail.

Maestro® Suspension | 160mmWhatever off-road adventures you seek, Giant's Maestro Suspension helps you make the most of your efforts. Control, traction, comfort, speed -- you get more of everything with Maestro. From fast and efficient XC bikes to long-travel downhill setups, Maestro is an adaptable full-suspension platform that offers smooth, active rear suspension for any type of trail and all kinds of terrain.

RockShox Super Deluxe Coil Select ShockThe trusted performance and ride quality that you expect from the Super Deluxe family in a shock that is as easy to understand as it is fun to ride. Now featuring Maxima Plush fluid, it's the perfect place to start honing in those riding skills.

RockShox Yari RCYari brings Pike's and the new Lyrik's acclaimed look and proven features, such as the 35mm chassis, Fast Black upper tubes and Solo Air™ or Dual Position Air™ spring systems, to a wider audience.

Shimano MT520 BrakesetThese powerful, four-piston brakes boost confidence by offering rapid initial pad contact and controllable power modulation. With a wide contact area and great heat insulation, these brakes stay consistent and responsive on long descents.


Giant DH 27.5 27mm WheelsAt 27mm wide, this tough aluminum wheelset is a great platform for today's wide trail tires. It features Tracker Performance hubs for a smooth and long-lasting ride.

Maxxis Minion DHR II Rear TireWith side knobs borrowed from the legendary Minion DHF, but widened to provide more support, the DHR II corners like no other. The center tread features ramped leading edges to improve acceleration and sipes to create a smooth transition when leaning the bike. Paddle-like knobs on the center tread dig in under hard braking and help keep the bike under control. Pair it with a Minion DHF up front for the ultimate aggressive trail riding tire combo!

Maxxis Minion DHF Front TireWith a tread design that deftly balances rolling speed with braking and cornering traction, it's hard to find fault with the Minion DHF. That's probably why it's one of the most imitated tires in mountain biking. Whether riding local trails, a backcountry epic, racing enduro or World Cup downhill, there's a Minion DHF spec to meet your needs.
