Giant 2023 Reign 1 S Airglow/Cold Night Bike

Rock the mullet style or go all in on 29. Either way, this new Enduro ripper is made to push limits on hard-charging terrain. Updated suspension eats up rocks, drops and whatever the trail throws your way, and a three-position flip chip lets you adjust all the angles to dial it in just right.

Race-bred suspension
A new Maestro rear suspension system with longer travel (160mm) was developed and tested under the extreme conditions of Enduro World Series races. The trunnion mount shock has a longer stroke (62.5mm compared to 60mm on the previous generation), and the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall weight.

Adjustable enduro geometry
New flip chip technology lets you switch between three settings depending on the terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm bottom bracket drop (size medium) to fine-tune handling for trail conditions, riding style and rear-wheel size.

Rear wheel options
Riders can choose either a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. The larger 29-inch option improves stability and roll-over capabilities, while the 27.5 option delivers a more agile, snappier feel. It's a quick and easy change to adjust the bike's handling and feel.

Highlights
The geometry of the ALUXX SL aluminium frameset has been updated to accommodate 29-inch wheels, and you now have the option to run a "mullet" setup with a 27.5 rear wheel. This translates into a short chainstay length, a shorter reach, and geometry that can be adjusted via a three-position flip chip. An updated Maestro suspension system delivers 160mm of rear wheel travel mated to a 170mm fork. And new integrated down tube storage provides convenient carrying capacity for trail riding essentials.

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

Flip Chip - Maestro 3
This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It's available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.
