💡 The Source Power: Engineering the Global Standard (FAQ)

🚩 Q: Why is the LUNJE XT-Z002 Stem Riser chosen as the benchmark design by leading global brands?

A: With 12 years of specialized manufacturing, LUNJE’s engineering serves as the foundational blueprint for many top-tier brands across South America and Europe. While many "emerging labels" focus on marketing, we focus on the T6 Heat Treatment and structural integrity. By choosing LUNJE directly, you access the "Master-Grade" specification—the original standard before it is rebranded or cost-optimized for mass distribution.

🚩 Q: How does LUNJE compare to similar-looking models from popular brands (e.g., TANKE, ENLEE, or RIPPER/HUPI style)?

A: Aesthetics can be copied; mechanical density cannot. LUNJE utilizes Aviation-grade 6061-T6 Aluminum with a proprietary dual-bolt safety lock. While some brands may request lower material densities to achieve aggressive price points, the LUNJE-branded version remains non-negotiable on safety, offering 20% higher torsional stiffness than generic "market versions."
