The Onyx ULTRA SS hub is the big boy of the formidable Onyx hub line up and is regarded in the circles of elite BMX racing as the only hub to run, bar none! The Ultra SS's versatility is one of its strongest features as it allows for multiple axle configurations from a 10mm bolt up spec, to 15 and 20mm thru-bolt versions. This means that you can swap frame brands without having to change your wheelsets, potentially saving you plenty of headache and dollars as we have the components at LUXBMX to re-configure Onyx hubs (front and rear). The highlights here are the ceramic hybrid bearings giving you virtually zero drag and the bigger patented sprag clutch mechanism.

Onyx's reputation has been forged in the cauldron of international UCI SX racing, with their hubs dominating gates in the 2020 Tokyo Olympics, withstanding the power output levels of the best racers in the world of BMX. There is absolutely one component you do not want failing on an 8m hill, and that's your rear hub. In addition to this bomb proof strength, the rear hub design featuring infinite engagement points means that you can place your crank height millimetre perfect on the gate. Maximising the drive of your first pedal, with the confidence that you can crank at full noise down any hill without the worry of hub failure.

LUXBMX has invested heavily in this brand and in addition to carrying the full BMX race range of hubs, has been approved by Onyx Racing Products USA as the Australian service centre for Onyx hubs and as such, carries a comprehensive range of spare parts for replacement, warranty work, and servicing of Onyx hubs. Offered uniquely under the Spectre brand in matte black, this is possibly the last rear hub you will ever have to buy.
