Giant Reign SE - Black Lightening - Medium

The Giant Reign SE (Special Edition) is a gravity-focused, mixed-wheel enduro mountain bike engineered for big hits, technical trails, and bike park terrain. Built with a lightweight, stiff, and super-strong ALUXX SL-Grade aluminum frame, it features a unique hand-finished paint treatment that makes every single bike one of a kind. Pairing 165mm of smooth Maestro rear suspension with a massive 180mm RockShox Zeb Ultimate fork, the Reign SE utilizes an adjustable 2-position geometry flip chip and integrated down tube storage. Outfitted with SRAM's direct-mount Eagle 90 T-Type wireless transmission and ultra-powerful SRAM Maven Silver 4-piston hydraulic brakes, it combines high-speed 29er front-wheel stability with agile 27.5" rear-wheel cornering maneuverability.
