Key Features
Instant Engagement
Onyx hubs use sprag clutch technology instead of traditional pawls. This delivers instant, lag-free engagement with every crank stroke – perfect for explosive gate starts and quick acceleration out of corners.
Silent Coasting
Unlike most ratchet-based hubs, Onyx hubs are completely silent while coasting, allowing you to focus on the race without the distracting noise.
Unmatched Power Transfer
With no backlash or slop, every bit of rider input is transferred directly to the wheel for more efficient pedaling and improved race performance.
Premium Bearings
Equipped with high-quality ceramic or hybrid ceramic bearings for ultra-smooth rolling and reduced resistance on the track.
Built to Last
CNC-machined from aerospace-grade aluminum in the USA, Onyx hubs are designed for extreme durability with minimal maintenance required.
