Onyx Racing Products are the premier and leading hub choice for all cycling disciplines, including MTB, BMX, road, and gravel as well as the rapidly growing ebike and EMTB segment. The patented sprag clutch mechanism is in the heart of every Onyx rear hub, providing the feel and performance Onyx hubs are known for.
Besides the class-leading performance and wide array of colour options, Onyx hubs have plenty of things on their sleeve which isn’t commonly known. Read further to learn about the most notable ones!
1) End caps with a high level of configurability! Want to switch from standard Boost to a 20mm Boost axle on your Vesper or Classic rear hub? Not a problem! Instead of needing to replace the whole hub, with the Vesper hub it’s just a matter of switching the end caps. With the Classic hub, the same conversion can be made by simply replacing the axle while keeping the current bearing preload lockring.

2) 3 bearings instead of 2. Most rear hubs employ two bearings in the shell (which are often times under-sized considering the application). Onyx rear hubs employ three bearings in the rear hub shell: brake side, central and driver support bearing.
The use of three bearings instead of two distributes the loads to three contact points instead of two, adds a considerable amount of load-bearing capacity, adds stiffness, keeps the wheel running smoothly, and improves bearing life.
3) Steel sleeve. The patented sprag clutch mechanism differentiates Onyx hubs from the rest of the field. The forces seen inside the mechanism are considerable, to say the least. In order to make the mechanism work and perform consistently over a long period of time, the hub shell is reinforced with a steel sleeve that’s pressed inside the hub shell, providing a strong contact surface for the sprag clutch mechanism that will deliver the performance Onyx hubs are known for each, and every time when force is applied. to the pedals.
This is a good example of the design considerations, and the level of manufacturing that goes into all Onyx hubs.

4) Ultra-low friction. The sprag clutch mechanism is fully silent in its operation. Besides that and the instant engagement it provides, it’s also the system with the lowest friction out there!
If you’re looking for a set of hubs for your wheels that roll “forever”, look no further!
And yes, this is backed up by science.

5) Ebike and EMTB approved. Ebikes with their powerful drive units subject the drivetrain to a great amount of stress – the rear hub included. Onyx Classic hubs are e-bike approved for bikes that have a mid-drive unit with a peak power output of up to 1500W.
If you’re looking for a set of hubs for your bike that will deliver class-leading performance day in, and day out, Onyx Classic is your choice.

6) Hook Flange technology. Berd Spokes – another forward-looking company residing in the state of Minnesota – has taken the world by storm with its PolyLight spokes. The collaboration between Berd and Onyx led to the innovative Hook Flange technology which makes lacing and building wheels with Berd PolyLight spokes a breeze!
Currently, the Hook Flange technology is available in the following hub models and applications.
