Onyx BMX Rear Hub

Unlike traditional pawl systems that rely on mechanical teeth to engage, the Onyx sprag clutch uses a series of sprags that wedge against the inner and outer races. This eliminates the 'click' sound entirely and provides zero-degree engagement, meaning your power transfer is instantaneous the moment you start pedaling.

The Onyx BMX Ultra Rear Hub is designed with a 110mm rear spacing and a 10mm axle diameter. Please verify that your frame matches these specific dimensions before purchasing, as it is not compatible with frames requiring different spacing or thru-axle standards.

The adjustable preload allows you to fine-tune the bearing tension to account for wear over time or specific riding conditions. By dialing this in, you can ensure the hub maintains its exceptionally smooth rotation without developing play, extending the life of the ceramic hybrid bearings.

Yes, for high-performance riding, the ceramic hybrid bearings offer significantly lower rolling resistance and improved durability. They are designed to spin more freely and handle the stresses of BMX racing better than standard steel options.

Yes, the hub is engineered to be versatile and supports both 6-bolt disc brake setups and traditional rim brakes, making it a flexible choice for various BMX builds.

The sprag clutch is highly reliable and requires minimal maintenance compared to pawl-based hubs. However, we recommend following the manufacturer's service intervals to ensure the internal components remain clean and properly lubricated for optimal performance.
