1. Advanced Heat Treatment Process

KOOVA team is conssisted of experts with over 30 years of heat treatment experience to precisely refine the ratchet heat treatment process.This breakthrough significantly enhances the shape stability, wear resistance, and crack resistance of the ratchet, ensuring exceptional performance even under high-intensity riding conditions.

Extended Durability – Enhanced wear resistance significantly prolongs hub lifespan.

Stable Power Transmission – Improved shape stability minimizes long-term wear and performance degradation.

High Impact Resistance – Superior crack resistance ensures reliability under extreme conditions.

2. Precision-Engineered Spring System

Through more than 30 trials and evaluations, we have identified the two most optimized spring wire diameters and force values. By precisely matching these elements, we ensure instant ratchet engagement, smooth operation, and minimal energy loss, enabling highly efficient power transfer.

Faster Engagement – Optimized spring force enables instant ratchet engagement with minimal lag.

Smoother Pedaling – Reduced mechanical resistance ensures a more natural and fluid riding experience.

Higher Power Efficiency – Minimized energy loss allows maximum power transfer to the drivetrain.

3. Industry-Leading Waterproof Design

KOOVA hubs feature fluororubber seals, a labyrinth structure, and high-precision waterproof bearings to ensure protection in extreme weather conditions. Whether in mud, rain, or high humidity environments, our waterproofing solutions effectively block moisture intrusion, guaranteeing long-term smooth operation.

Extended Hub Lifespan – Prevents water ingress, reducing rust and wear on internal components.

Consistent Performance – Maintains smooth operation even in wet or muddy environments.

Reduced Maintenance – Less frequent cleaning and servicing required due to superior sealing.

4. Professional-Grade Lubrication System

The choice of lubricant is crucial to hub performance. Through extensive testing, KOOVA has selected a fixed-viscosity lubricant that meets multiple requirements, including wear resistance, rust prevention,low viscosity, and self-lubrication. This ensures that our hubs maintain efficient under prolonged high-load riding conditions.

Smoother Power Output – Low-viscosity grease reduces friction, improving efficiency.

Enhanced Longevity – High-wear resistance protects the ratchet and pawl system over time.

5. High-Precision Manufacturing

Each KOOVA hub is precision-engineered using 5-axis CNC machining, ensuring every component meets micron-level tolerance standards. Our process has been refined over years of development, achieving the perfect balance of weight, rigidity, and durability.
