🧪 Material Performance
Manufactured from Grade 5 Ti-6Al-4V titanium, each component is engineered for high-strength drivetrain applications:
• Tensile strength: ≥1050 MPa (Exceeding the industry standard of 895 MPa)
• Superior strength-to-weight ratio vs 10.9-grade steel
• Approx. 50% weight reduction compared to OEM hardware
• High corrosion resistance for all-weather riding conditions
⚙️ Precision Engineering
• CNC machining with micron-level tolerance control
• Hot-forged at 650°C for optimized structural grain alignment
• Limited tooling lifecycle manufacturing (≤300 cycles per die) ensures consistency and pristine tool-slot engagement
• Aerospace-level inspection standards for drivetrain reliability
🎨 Surface Finishing Options
• PVD Vacuum Nitriding Coating (Gold / Black / Blue / Rainbow)
Ultra-durable surface layer with deep bonded coloration for high abrasion resistance. Repels rain, mud, and grit.
• Anodized Electro-Oxidation (Purple / Green / Indigo / Candy)
High-saturation custom colors for personalized drivetrain aesthetics, turning the crank cap into a token of cycling fashion.
🚴 Performance Benefits
• Full drivetrain hardware weight reduction
• Improved corrosion resistance over OEM steel fasteners
• Precision fit for SRAM RED AXS E1 shifting system
• Enhanced mechanical reliability under high load shifting conditions
• Premium visual upgrade for high-end road and gravel builds
