SD17 Integrated ratchet design hub for carbon spoke

Core Innovation: Internal Integrated Ratchet Hub

The highlight of this upgrade is our brand-new internal integrated ratchet structure, which completely redefines traditional hub transmission and maintenance:

• Simplified Installation & Maintenance: The one-piece design drastically reduces internal component complexity, making disassembly, cleaning and servicing far more straightforward, lowering long-term ownership costs
• Stable & Reliable Engagement: Replacing traditional discrete pawl systems, the integrated ratchet distributes power evenly across the full circumference, eliminating slippage and dead strokes caused by pawl wear over time, for crisp, immediate power transfer
• Perfect T-shape Spoke Compatibility: Hub flanges are precision-engineered to interface seamlessly with T-shape carbon spokes, enhancing overall wheel stiffness and durability
