Giant Reign Advanced Pro 2 29er 2023
The Reign platform was initially introduced in 2005 as one of the first Giant mountain bikes to feature Maestro suspension. A lot has changed in the nearly two decades since, and Reign has continually evolved with the times. From suspension technologies to wheel sizes, frame materials to geometries, it’s a bike that has been pushing the boundaries of trail riding progression since before modern enduro racing even existed. It has racing in its DNA, but is equally at home in the bike park or on backcountry rides.
The new Reign Advanced Pro and Reign series allow riders to choose 29-inch wheels front and rear, which is how they arrive from the factory, or swap out the rear for a 27.5-inch wheel. (The Reign SX must be ridden in the 29-inch front and 27.5-inch rear wheel configuration.) And the new range offers even greater adjustability with three flip chip settings to dial in frame geometry including head and seat tube angles, along with the bottom bracket drop.
REAR WHEEL OPTIONS
The new flip chip setup offers the option to use a 27.5-inch rear wheel (paired with a 29-inch front wheel), which gives the bike more saddle-to-tire clearance in the rear. Some riders prefer this mullet setup for steep, technical terrain.
Using the stock 29-inch rear wheel optimizes stability and roll-over capabilities, while the 27.5-inch option delivers a more agile, snappier feel. It’s a quick and easy change to adjust the bike’s handling and feel.
FLIP CHIP - MAESTRO 3
A new three-position flip chip lets you adjust the geometry to suit your riding style and terrain. It offers bottom bracket drop adjustments in 5mm increments (35, 30 or 25mm) and also lets you change the head tube angle (63.5. 63.9 or 64.2 degrees) and seat tube angle (78.3, 78.7 or 79 degrees).
The high position of the flip chip increases ground clearance, a good option for tighter, more technical terrain. In this position, the steeper seat tube angle helps you power up climbs. Put the flip chip into the low position, and the head tube gets slacker and the bottom bracket drops. This gives the bike more confident handling at higher speeds. For those who want a more neutral setup, the middle position is a versatile option.
