🏆 The Stem That Defined a Category 
Since 2018, this LUNJE XT-A015 stem has set the standard for lightweight CNC construction—proven on trails worldwide and trusted by leading brands. This isn't just another stem; it's the original hollow-out design that competitors still try to replicate.


🔥 Why This Stem Dominates OEM Orders

1. ENGINEERED LIGHT, BUILT STRONG 
• True Hollow-Out CNC Design: 5-axis machining removes every possible gram without sacrificing DH-level stiffness—no fake cutouts or cosmetic gimmicks. 
• Short & Aggressive Geometry: 35mm/45mm lengths deliver instant steering response for technical trail and enduro riding. 
• Aircraft-Grade 6061-T6: Heat-treated and CNC-finished for the optimal balance of strength and fatigue resistance.

2. THE TWO-TONE ANODIZING PIONEER 
• Industry-First Finish: We developed the dual-color anodizing process that became the benchmark for premium aesthetics. 
• UV & Scratch-Resistant: Colors stay vibrant through seasons of sun, sweat, and abuse. 
• Brand-Defining Colors: From stealth black to holographic oil slick—customize your signature look.

3. SGS-CERTIFIED & MARKET-PROVEN 
• Independently Verified: Tested to exceed ISO 4210 standards for load, fatigue, and safety. 
• 5 Years of Real-World Validation: Trusted by downhill racers, enduro teams, and volume brands globally. 
• Zero Compromise Reliability: Every stem is torque-tested and inspected before shipment.

4. STRATEGIC PARTNER PROTECTION 
• Exclusive Series for Distributors: Differentiated A/B versions prevent cross-market competition and protect your margins. 
• Full EU/US Compliance: LUCID-registered (VerpackG) and EPR-ready for seamless import into regulated markets. 
• True Factory-Direct Pricing: No brokers or middlemen—work directly with our engineering team on custom solutions.
