2023 Giant Reign 1 Mens Mountain Bike in Silver/Navy

Season:2023

Brand:Giant

Code:2311303AirglowColdNight

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.

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.

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.

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.
