Giant Reign Advanced Pro 1 Bike
The Giant Reign Advanced Pro 1 is a race-ready enduro weapon that begs for the steepest line.
The Advanced Pro 1 is Giant's top-tier Reign build, full carbon, big travel, and a component spec ready to race. It's for the rider who charges gravity and hunts descents. Take it to the gnarliest lines in the Santa Monica Mountains and let it do what it was born for.
It's right for you if:
You race enduro or ride at that level
You want a full-carbon frame, front and rear
You demand a high-end build straight off the floor
You want the lightest, stiffest Reign we offer
Why you'll love it:
Full Advanced Pro carbon frame delivers race-level stiffness and lower weight for faster climbs and precise descents
160mm Maestro suspension keeps the rear wheel glued through the roughest terrain
Premium drivetrain and dropper spec means fewer upgrades and more riding
Powerful hydraulic disc brakes give you control at speed
Aggressive enduro geometry inspires confidence on the steeps
The tech you get: an Advanced Pro full-carbon frame, Maestro suspension with about 160mm of rear travel, a long-travel fork, a 1x drivetrain, hydraulic disc brakes, and a dropper post.

Highlights
Composite Enduro Chassis
An all-new carbon frame built strong, light and fast for Giant's enduro racers. This is the sharp end of the Reign line, tuned to go hard and hold up.
160mm Maestro Plus Fox 38
The Maestro rear pairs with a burly 170mm Fox 38 Performance Elite and its GRIP2 damper. Big travel with fine control, so you can hit lines that used to scare you.
Three-Position Flip Chip
Switch between three head-angle settings to steepen up for pedaling days or slack out for full-send descents. The bike adapts to the ride instead of the other way around.
SRAM GX Eagle 1x12
A proven wide-range wireless-ready drivetrain that shifts clean under load. Twelve gears from steep climbs to flat-out sprints between features.
Integrated Down Tube Storage
Stash a tube, tool and snack inside the frame and leave the pack at home. Everything you need for the loop rides with you, out of the way.
Giant TRX Carbon Wheels
Light, stiff carbon rims wrapped in a Maxxis Assegai front and Minion DHR II rear. Precise steering and serious grip for the rowdiest terrain.
