2025 Giant Reign 1 Men's Mountain Bike, Mars Dust

PUSH NEW LIMITS ON CHALLENGING TERRAIN. THIS ENDURO RIPPER HAS 160MM OF REAR SUSPENSION THAT EATS UP ROCKS, DROPS AND WHATEVER COMES YOUR WAY. A THREE-POSITION FLIP CHIP LETS YOU ADJUST GEOMETRY AND SWITCH OUT THE REAR WHEEL FROM 29-INCH TO 27.5.

Race-bred suspension
A Maestro rear suspension system with 160mm of travel 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).

Adjustable enduro geometry
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 depending on the frame size.

Rear wheel options
Riders can choose either the stock 29-inch rear wheel or switch to 27.5. 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 way to adjust the bike’s handling.
