Shop all Giant Shop sale GiantCoupling a sensible all-mountain design with mountain mashing suspension and select DH-specific components, the Giant Reign Advanced 1 Complete Mountain Bike was built for sending it to the flats. The latest Fox 160mm front and rear travel, a cutting edge SRAM GX Eagle™ drivetrain and a chatter-absorbing composite frame ensure that the Giant Reign Advanced 1 Complete Mountain Bike has the stuff to take on the spiciest lines your heart desires.
Advanced Composite with ALUXX SL Rear Triangle – Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in their own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
Advanced Forged Composite Upper Rocker Arm – A state-of-the-art high-pressure molding process is used to produce complex-shaped carbon fiber components that are lighter, stiffer, and stronger than similar components made from aluminum. This technology is used in critical performance parts such as Maestro Suspension rocker links.
Maestro® Suspension | 160mm – Whatever 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.
Fox Float DPX2 Performance – X2 small bump sensitivity meets an improved DPS adjustment range Recirculating oil damper design gives riders better control. One-piece EVOL air sleeve improves responsiveness and sensitivity.

Trunnion Mount – The 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. The Advanced Forged composite rocker arm weighs less than the previous aluminum version while being stiffer and stronger. Together, these innovations result in the following core benefits.
OverDrive – OverDrive provides up to 15 percent more torsional steering stiffness than straight steerer-tube designs. This translates into much more accurate steering input from a rider's hands, through the handlebar and stem, and down to the front wheel. Whether hammering uphill or carving through a corner, OverDrive transmits input directly to the front wheel for more precise handling.

Fox 36 Performance Elite – More than an enduro race fork. Now featuring an EVOL air spring and updated upper tubes for unparalleled small bump sensitivity, the 36 is even smoother than before. Performance Elite forks retain the same adjustments, dampers, weight, and 7000 series aluminum upper tubes as Factory Series, but have black anodized upper tubes instead of Genuine Kashima Coat.

Truvativ Descendent 6k Crankset – The Descendant 6K crankset delivers consistent performance every time out. Featuring SRAM's X-SYNC™2 tooth profile chainring, the Descendant crankset is engineered for complete chain control. Each tooth’s thickness is precisely toleranced and controlled to work seamlessly with the SRAM chain’s inner and outer links.
SRAM GX Eagle™ Trigger Shifter – The challenges of riding a mountain bike should be kept to roots, rocks, mud, trees, jumps, drops and breathing. Putting total control of your gear selection into the thumb of one hand, it’s simple to find the right gear, right now. The GX Eagle™ trigger shifter is the control center of the Eagle™ drivetrain. Its internal works have been updated to include a 12th gear, and improved to enhance trigger feel, precision and durability.
SRAM GX Eagle™ Rear Derailleur – This new GX derailleur not only answers the Eagle™ drivetrain’s need for greater capacity, but it’s also the next evolution of the proven, 1x-specific X-HORIZON™ design. The larger, 14-tooth X-SYNC™ lower pulley allows 10- to 50-tooth cassette, and also adds to Eagle’s overall smooth-pedaling feel. The new, Type-3 ROLLER BEARING CLUTCH™ features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK™ has been moved back and out of the way, protecting it from trail debris. And a redesigned, robust mounting system further improves the Eagle™ derailleur’s performance and overall durability.
SRAM XG-1275 Eagle™ Cassette – Ride anywhere with this wide range XG-1275, 10- to 50-tooth Eagle™ cassette that provides the right gear. Fast on the flats. Control on the climbs. Dictate your own pace, anywhere. Only Eagle™ technology is the 1x drivetrain engineered for infinite freedom. FULL PIN™ technology uses lightweight, stamped steel cogs held together with high-strength stainless steel pins. The result: a cassette that’s light and strong. The open design similar to the X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life. New X-GLIDE™2 improves both inboard and outboard shifting, as well as chain retention.
SRAM GX Eagle™ Chainring – The radical new look and feel of the X-SYNC™ 2 Eagle™ chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC™ chainrings. We subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagle™ drivetrain’s performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle™ chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.
SRAM Guide RS Hydraulic Disc Brakeset – Fast isn’t about pure speed, it’s about perfect speed. It’s about knowing the right line and having the confidence to ride it. Flawlessly. The new SRAM Guide RS is precision at your fingertips, with a proven 4-piston caliper and innovative SwingLink™ lever technology that gives you more positive pad contact and increased braking authority. Light, crisp, clean and now compliments your SRAM drivetrain. Go faster. Now featuring the World Championship-winning S4 caliper with Bleeding Edge™ and Heat Shield technologies.
Maxxis Shorty Front Tire – Today's World Cup downhill tracks are steep, technical monsters with ever-changing conditions. Maxxis pros needed a mid-spike tire that could handle dry, loose, blown-out corners as well as a bit of mud. The Shorty is that tire. A high-volume, dual-ply downhill casing makes the Shorty a more versatile option than a dedicated mud spike like the Wet Scream. Large, tall and slightly staggered side knobs penetrate loose soil to provide predictable, stable cornering at warp speeds. The alternating pattern of the center tread features widely-spaced knobs to clear debris, and their square shape offers plenty of braking bite. For downhill mountain biking in gnarly, mixed conditions, the Shorty can't be beat!
Maxxis High Roller II Rear Tire – The open and aggressive tread design gives the High Roller II excellent soil penetration and mud clearing ability. A square profile provides a solid, consistent feel across the knobs. Modified knobs on the shoulder and center improve braking performance and traction on hard surfaces. When gravity pulls you downhill, rely on the High Roller II to keep you upright.
Giant Contact S Switch Dropper – Trail conditions change in the blink of an eye -- transition from steep climbs to gnarly descents and never skip a beat with the all-new Contact SL Switch seatpost.
