GIANT REIGN SX FULL SUSPENSION MTB BIKE 2023 GLOSS PURPLE/PETRA CLAY

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.

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.

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 manoeuvrability to help riders rail corners, pop over features and show off their style.
