Reign SX – Giant Melbourne


Reign SX

Dial in the frame geometry for your riding style and terrain, then let it rip. This new shapeshifter enduro bike delivers confidence and control on the rowdiest terrain. Its mixed wheel size, 29-inch front and 27.5 rear, blends stability and speed with agility that pops.

This gravity-focused enduro machine features a lightweight, stiff and super-strong ALUXX SL frameset paired with our latest Maestro rear suspension. The geometry has been updated to provide added suspension travel in the rear (165mm) along with a 190mm fork to take on the roughest trail conditions. You can adjust frame geometry with a flip chip that lets you switch the head tube and seat tube angles, along with bottom bracket drop to dial in the handling for your riding style and terrain. A new integrated down tube storage feature provides convenient carrying capacity for on-trail essentials.

Race-bred suspension: The Maestro rear suspension eats up enduro terrain with 165mm of smooth, active rear travel matched with a 190mm travel fork. The trunnion mount rear shock has a longer stroke (65mm over 60mm on the previous generation) while the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall frame weight.

Adjustable enduro geometry: New flip chip feature lets you adjust frame geometry depending on the terrain. You can select a 63.1 or 63.5-degree head angle and corresponding 77.9 or 78.3-degree seat tube angle, resulting in a 25 or 19mm bottom bracket drop (size medium) to fine-tune handling for varying trail conditions and riding style.

Mixed wheel size: A 29-inch front wheel provides speed, stability and front-end control on rough, technical trails. A 27.5-inch rear wheel adds agility and maneuverability to help riders rail corners, pop over features and show off their style.

Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
