The Pinnacle of MTB Control: LUNJE® XT-A032 5-Axis CNC Stem

Engineered for elite MTB, DH, and Enduro riders, the XT-A032 is a masterpiece of precision. As a leading China stem manufacturer, we’ve combined 5-axis CNC machining with a patented 3D dynamic tiger stripe design to reduce wind resistance and enhance industrial aesthetics.

✅ 35mm Ultra-Short Reach: Delivers instant steering response for ultimate control in technical sections. ✅ 5-Axis CNC Precision: Machined from 6061、7075-T6 aluminum alloy (high-strength, low-weight). ✅ 150g Lightweight Hollow Structure: Optimized strength-to-weight ratio for aggressive riding. ✅ Military-Grade Gradient Anodization: Superior corrosion resistance with a premium multi-angle refraction finish.

Whether you are looking for Bulk MTB components or a reliable OEM partner, the XT-A032 offers battle-tested performance for global brands.
