Meet the new Onyx Vesper hubs!

Onyx Racing Products is a US manufacture of high end hubs. They have been known for their vast array of color options, instant engagement, and unique silent sprag clutch design. The one downfall however is that they weigh more than other hubs. For most customers, the efficiency offsets the weight gain, but for others it was a hurdle. After 2+ years of development, the new generation of lightweight sprag hubs are here, same features as before but without the added weight. Enter the Vesper!

How much weight was really saved?

Let’s take a look at the actual hub weights of the most popular options.

Specs Generation1 Vesper Rdition
15/110mm Boost 32h 6-Bolt 226g 177g
15/110mm Boost 32h Centerlock 225g 155g
12/148mm Boost 32h 6-Bolt(SRAM XD) 474g 409g
12/148mm Boost 32h Centerlock 449g 372g

The Vesper hubs were weighed with steel bearings. Upgrading to ceramic bearings (more on that later), saves 9g per hubset. MicroSpline freehubs add 5g, Shimano HG freehubs add 9g. All rear hubs were weighed with Sram XD Alloy Freehubs.

The new boost CL Vesper hubset with an XD freehub and ceramic bearings weighs in at 518g, a whopping 156g lighter (1/3 of a pound) compared to the last generation. That’s about the same weight as Hope Pro 4’s, Lighter than most Chris Kings, and within 100g of really lightweight hubs like Industry Nine Hydra and DT240’s.

How did they do it?

1. The majority of the weight savings has come from reducing the overall width of the sprag grouping. The sprags, drive axle and sleeve are all made of steel. So by reducing the width of the sprags, they can reduce the other steel components. Alternate materials were explored for these parts but they can’t adequately handle the loads long term.

2. The revamped freehub design uses a new interface to engage with the steel drive axle. Their original freehub system was 100% steel because the sprags ultimately needed to ride on the steel axle as well. A lighter alloy freehub was released, but it was bonded to a steel sleeve and in some cases there was an issue of the materials expanding and developing a hairline crack due to the 2 dissimilar materials being sleeved together. A retrofit on their last generation of hubs will become available to switch to this new freehub system.

3. The hubshells have been refined to machine out as much material as possible. They are made in 6-bolt (ISO) and the increasingly popular and lighter weight Centerlock variation.

What else is new?

Bearing Changes - The Vesper hubs come with steel bearings as standard. There is an option to upgrade to faster rolling Verinent bearings which use ceramic balls. The other tweak is that heavier duty (double lip) seals are used on the outboard side of the bearings in order to increase protection against the elements. The side of the bearings that isn’t as exposed to the elements uses a low drag RS seal (single lip). It costs $100 for the rear and $60 for the front to upgrade to the ceramics. The rear is more expensive because you’re getting a ceramic upgrade to the freehub as well.

Axle and End Caps - A simpler end cap/axle design is now used so that there are more shared parts between the various hub standards. You can swap between different freehubs and even change the axle width standard without having to change out the actual axle. The end caps pop on without needing to thread them on.

Freehubs - The Sram XD option is technically an “XD-R” meaning it is wider than a standard “XD” and is compatible with XD Road cassettes which is something new to the market. Onyx has decided to future-proof this freehub. 99% of riders will be running the provided spacer behind your cassette as mountain bike cassettes are slightly narrower than their road counterparts. Shimano HG, MicroSpline and Campy freehubs are also available.

Pre-order is available now!

Are fatbike hubs going to get the Vesper upgrades?

No, not at this time.


Can I get a steel version of the Shimano HG Freehub?

Yes, we can do this by special order and they are the same cost as the alloy ones.


Can I get a Steel XD freehub for the Vesper?

No, not at this time.


Why does it say XD-R instead of XD on the freehub?

The new freehubs are compatible with road XD-style cassettes. You will need to run a spacer behind your mountain bike cassette on the XD-R freehub. We will provide this with your wheelset purchase.


Can the Vesper hubs be engraved?

Yes they can. We can offer this service when the initial rush is over. We anticipate this will be available starting in July 2019. E-mail us to discuss.

Hi Phillip, Yes, according to Onyx Racing hub, the Vesper hubs will be delayed. Here's the pre-order invoice for you, we can settle other details of road disc wheels when you are ready. https://www.lightbicycle.com/invoice.php?no=E4oeGhz2SoTEV3AiRULU8%2F0S92BnRsZFkg Thanks, Lightbicycle

i don't mind pre-ordering, esp for the discount but i would like to do the wheel set at the same time if i do it. and i'd like an ETA, beyond which i'd be able to get my money back if i did not want to wait any longer - is that possible? trying to decide on this vs the i9.....

Hi Geoffrey, Onyx told us "early June", so we are anticipating having orders ship to us this upcoming week and then we'd have them next week. We have several dozen wheelsets that require the Vesper hubs on pre-order already so we'll be very busy following the first shipments arrival. We can offer the pre-order to you but realistically it will be approximately 3 weeks from now before we could fulfill your order if you choose the Vesper hubs. Naturally we'll try our best to cut that lead time down, but I want to keep things realistic for you. Does that kind of timeline work? Thanks, Lightbicycle ​
