2025 Giant Reign Advanced Pro 29 1

2025 Giant Reign Advanced Pro 29 1

The Giant Reign Advanced Pro 29 1 is built around a geometry developed specifically for 29-inch wheels — shorter chainstays, a longer toptube, and dialed angles (64.56° head tube / 76.36° seat tube) that translate to absolute confidence on the trail. The updated Maestro rear suspension delivers 146mm of super-plush, active travel via a trunnion mount shock and Advanced Forged Composite rocker arm. Pair that with a Fox 38 Factory Live Valve fork and you have one of the most capable enduro bikes on the market.
