- 1.Aerospace-Engineered 7075-T6 Alloy7075-T6 Aluminum Alloy - 572MPa tensile strength (30% stronger than 6061), 5-Axs CNC Machined - 0.01mm tooth tolerance (ISO 13041 certified), Military-Grade Hard Anodization - HV800 surface hardness (3x wear resistance), Compatibility: Compatible with 104BCD Single Bike Chainring Shimano/SRAM 8-11 Speed MTB/Road Bikes
- 2. DynamicChain 3.0 Anti-Drop SystemAlternating Narrow-Wide Tooth Profile (7.3mm wide / 6.8mm narrow teeth) perfectly matches 8-11 speed chain pitches. Dynamic Chamfer Technology enables 45% faster chain engagement, tested to reduce chain drops by 92% on rough terrain. Extended Tooth Tips enhance stability, ideal for high-impact MTB rides and aggressive road cycling
- 3. 3D Ultra-Lightweight Architecture3D Hollow Structure cuts weight by 63% compared to steel, achieving a featherlight profile without compromising strength. Asymmetric Reinforcement Ribs deliver 155Nm/deg lateral stiffness, ensuring power transfer efficiency up to 98.7%. 1kg Total Weight Reduction for your bike, boosting climbing performance and overall agility
- 4. Biomechanical Oval Advantage Lab-Proven Efficiency Boost: 15% pedaling efficiency increase vs round chainrings (University of Colorado validated) 12 optimal ovality (reduces knee strain by 18%) Dual-Performance Profiles: Race Mode: 90 RPM cadence optimization Enduro Mode: Enhanced torque output (60-80 RPM). Mirror-Polished Teeth (0.09 ultra-low friction coefficient) minimize energy loss during pedaling. Self-Cleaning Grooves reduce mud accumulation by 70%, maintaining peak performance in wet or dirty conditions.
