Product Line


The Classic hub line is synonymous with reliability and is known for the features that have made Onyx Racing products hubs the premiere choice for riders looking for superior performance.

The Classic line is the hub of choice for heavy-duty riding and use cases such as downhill, e-mtb, bike packing, or tandem riding.

Vesper is the lightweight option for those looking to save some weight, but still enjoy the legendary instant engagement and fully silent operation the Onyx Racing Products hubs offer.

If unsure which hub model is the right for you, refer to the article which describes the main differences between these two product lines.

The addition of electrical assistance puts adds some considerable demands to the bike’s componentry, especially on the drivetrain. The Classic hub line handles the additional torque and stresses applied by the motor with ease.

With the exception of Ultra SS BMX hub, the Classic rear hub has the strongest sprag clutch mechanism available in the Onyx Racing Products lineup, making it an undisputed choice for transferring all the power from the motor and riders legs to the rear wheel. No uphill is too steep, and no downhill is too long for the Classic hub.

If you are looking to save some weight, feel free to mix and match Vesper and Classic hubs so that the former is run in the front, and latter in the rear where the ultimate durability is asked for.

Fat Bike

Reliability and the ability to transfer torque to the rear wheel even in the steepest inclines and toughest of conditions is the name of the game when it comes to drivetrain performance in fat bikes.

The Kluber Isoflex lube used in the patented sprag clutch mechanism has a temperature operating range between -50°C  to 120°C – adequate to say the least. Whether you’re tackling the prestigious Iditarod Invitational or completing a bike packing trip across sand dunes in high temperatures, Onyx hubs won’t be holding you back.

The Onyx Racing Products fat bike lineup is based around the tried & true Classic lineup, covering all the imaginable spacing options, axle diameters, disc mount interfaces, and freewheel drivers available.

On top of this, it certainly does not hurt that the color options are the widest in the market, making your hubs and wheels built around them a standout feature in any bike, no matter how classy the rest of the build is.
