All-New Integrated Ratchet Hubs for Carbon Spoke Wheelsets

Apr 15, 2026
As cycling technology continues to evolve, carbon spoke wheelsets have gained unprecedented popularity for their exceptional lightweight, high rigidity and superior vibration damping performance. Their application has rapidly expanded from road bikes to gravel bikes and now the entire mountain bike category.

To deliver an unparalleled riding experience, we have completed a core technical upgrade for our full carbon spoke wheelset lineup: launching custom-built internal integrated ratchet hubs exclusively for T-shape carbon spokes, alongside an optimized carbon spoke product line. This dual upgrade elevates performance across the entire drivetrain and wheel assembly. Currently, all our rim specifications – Road, Gravel, and MTB (including 32") – are fully configurable with the upgraded carbon spokes and new hubs.


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:

Ornan Integrated Ratchet design

  • 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

Carbon Spoke Upgrade: Next-Level Lightweight

Alongside the hub innovation, we have refined our carbon spoke lineup with two new options tailored to different rider needs:


  • 32" MTB Specific Carbon Spoke: Weighing just 3.6g per piece, engineered for the high-impact demands of large-diameter mountain biking, balancing lightweight performance with exceptional impact resistance.
  • Ultra-Light Titanium Nipple Carbon Spoke: Our all-new flagship spoke, weighing an industry-leading 2.1g per piece, featuring a titanium nipple head for further weight reduction, ideal for competitive riders chasing ultimate lightweight performance
