Introducing the Pinnacle Series: Redefining Hub Performance
Engineered for cyclists who demand nothing but the best, we present the Pinnacle Series High-Performance Hubs—a fusion of innovative design and precision craftsmanship. Constructed from aerospace-grade alloys and hardened stainless steel, these hubs deliver unmatched longevity and rotational fluidity through advanced CNC machining and robotic assembly protocols. The patented dual-row bearing architecture ensures radial and axial load resilience, while the carbon-fiber reinforced pawl mechanism slashes weight by 30% compared to traditional designs.
Versatile Performance Across Disciplines
Urban Mobility: Seamless integration with disc brake systems and 60T rapid engagement hubs enable swift acceleration through traffic. The labyrinthine seal design repels water, mud, and road debris for maintenance-free commuting.
Trail Conquest: Overbuilt 15mm thru-axles paired with angular contact bearings absorb impacts on rock gardens, while the 108-point engagement freehub maintains momentum on technical climbs.
Velocity Racing: Aero-optimized flange geometry minimizes wheel dish, and the titanium freehub body reduces rotating mass for track-dominating efficiency.
Installation & Maintenance Expertise
Precision Assembly: Use a torque wrench to secure hub shells (12-24 Nm) and laser-align spoke tension for even load distribution.
Bearing Optimization: Adjust preload with a dial indicator to achieve <0.02mm radial play—critical for balancing longevity and responsiveness.
Proactive Care: Perform quarterly inspections using a borescope to check for pawl wear or contamination. Replace bearings every 5,000 km or when lateral play exceeds 0.1mm.
Technical Insights
Q: How do hubs impact ride quality?
A: As the rotational core, hubs determine power transfer efficiency. Our designs minimize friction through ceramic-coated races and optimized pawl geometry, translating every watt into forward motion.
Q: What factors guide hub selection?
A: Prioritize axle diameter (12mm for XC, 15mm for enduro), engagement speed (3° vs 10°), and material choice (aluminum for weight, steel for durability). Our configurator matches hubs to bike type, rider weight, and terrain.
Q: How to address hub noise?
A: Disassemble and inspect for pitted bearings or fractured pawls. Use ultrasonic cleaning to remove abrasive particles, then relubricate with high-temp grease. Replace components if wear exceeds 0.05mm.
Q: When to upgrade hubs?
A: If you experience notching during coasting, play beyond 0.2mm, or repeated bearing failures within 12 months. Our lifetime warranty covers premature wear—submit diagnostics via our app for priority replacement.
Elevate your ride with hubs that harmonize strength, precision, and innovation. The Pinnacle Series isn’t just built to last—it’s engineered to lead.
