Origin

Giant introduced the Reign in 2005 as one of the first bikes to carry their newly developed Maestro four-pivot rear suspension, and it has shaped Giant's long-travel trail and enduro line ever since. At launch the Reign offered some of the most aggressive geometry and longest travel available from a major brand, well before enduro existed as a discipline; by 2013 Giant produced the first carbon Reign using their Advanced Composite Technology, and 2015 brought 27.5-inch wheels and an even more aggressive geometry update. The current generation runs 160 mm of Maestro rear travel paired with a 170 mm fork on the standard Reign, while the Reign SX pushes to 165 mm rear with a dual-crown 190 mm fork for park use. All current Reigns get a three-position flip chip that adjusts BB drop, head angle (63.5° / 63.9° / 64.2°) and seat angle, and the wheel size is mullet-capable — 29-inch front, with the option to drop a 27.5-inch wheel in the rear. The Reign SX is mullet-only. Frames are ALUXX SL aluminium on the standard models and Advanced composite on the carbon versions, with European pricing typically ranging from around €3,000 for the alloy Reign 2 to €5,500+ for top builds.
