LUNJE XT-Z002 Fork Stem Extender Height Adjustment Range
The adjustable height feature spans five positions—85, 115, 150, 180, and 210 millimeters—allowing precise customization of hand position across the entire vertical range required by riders of different proportions and riding styles. Aluminum construction keeps the extender lightweight while maintaining the structural stiffness necessary for safe, play-free steering response even at maximum extension. The handlebar rise up adapter design bridges the gap between stem and fork crown, creating a clean integration that preserves the aesthetic lines of your MTB power setup. Each height increment redistributes your upper body weight progressively, reducing fatigue during climbing intervals and improving control during rapid descents. The LUNJE XT-Z002 excels for riders rebuilding vintage bikes with modern components, recovering from injury with ergonomic adjustments, or simply seeking the comfort advantage of higher hand positioning on challenging terrain.

Satisfied with the product and the quality is good and the size too. Furthermore, i did well to take 150 mm maximum beyond the front fork brake cables would have complicated the mount.
