Spank Wheels with Onyx Hubs
Custom Spank Wheels on Onyx Hubs
Pick a Spank rim we carry, put it on an Onyx hub, and we lace and true the wheel by hand in our Georgia shop.
Why build Spank rims on Onyx hubs:
- Made by specialists: Spank rims made in Spank's own factory, Fratelli Industries, on Onyx hubs machined in Minnesota
- Proven: Spank's Vibrocore damps trail vibration and raises fatigue life; Onyx drives through a sprag clutch, with no teeth to skip
- Built to last: Onyx hubs coast silently, with no pawls to wear; Spank shotpeens the surface rather than machining metal away
- More than 20 Spank wheels on Onyx hubs in our build records since 2009, each laced and trued by hand in Georgia
- In depth below: Spike Race 33 gravel · 359 Spike Vibracore mountain

Gravel in depth
Spank Spike Race 33 wheels on Onyx MTB Centerlock hubs
Our gravel pick from the Spank and Onyx parts we build with. The Spank Spike Race 33 is a hooked aluminum rim, 28mm inside, 22mm deep, sized for about 40mm to 2.2 inch tires. We lace it to Onyx MTB Centerlock hubs in 32 hole.
- Bead Bite. This is Spank's patented anti-burp design at the bead. It is there to keep the tire in place and hold pressure, including at lower pressures.
- Power that does not wait for a tooth. Onyx says the hub carries your pedaling to the rear wheel instantly, for faster acceleration and more control. There is no gap between teeth to cross before it picks up.

Mountain in depth
Spank 359 Spike Vibracore wheels on Onyx MTB Centerlock hubs
Our mountain pick from the Spank and Onyx parts we build with. The Spank 359 Spike Vibracore is a hooked aluminum rim, 30.5mm inside, 19mm deep, about 610 grams in 29 inch, sized for about 2.3 to 2.6 inch tires. We lace it to Onyx MTB Centerlock hubs in 32 hole.
- Sacred Geometry on the 369. A hollow bead wall improves lateral and vertical strength, Spank says, and its extra width reduces pinch flats and raises impact resistance. The 369 is 39mm outside on the same 30.5mm inner width as the 359.
- A weight trade-off. These hubs are heavier than pawl hubs, so they suit riders who want the engagement and the silence enough to carry the extra grams.

Why the pairing, specs and FAQ
Custom hand built Spank wheels on Onyx hubs
Our order records show more than 20 Spank wheels laced to Onyx hubs since 2009. We lace each wheel by hand in our Georgia shop: tensioned evenly, trued flat and round, and stress-relieved before it ships. Spoke lengths are calculated from the measured dimensions of your exact rim and hub.
What Spank rims and Onyx hubs each bring
- A low, radially compliant section. The 359 and 369 stand 19mm tall and are meant to give a little under load. Spank says that improves traction over bumps and chatter and reduces harsh feedback, while the wide shape holds lateral stiffness.
- Vibrocore in the inner well. On the Vibrocore versions, Spank injects Vibrocore into the rim's inner well. Spank says this cuts vibration reaching the suspension and rider, adds torsional strength and increases fatigue life.
- OohBah rim center. Spank corrugates the center of the rim, which it says adds strength and rigidity. That lets the rim be wider without adding material.
- A patented sprag clutch instead of pawls. Onyx hubs drive through a sprag clutch, not pawls and a toothed ring. With no teeth in the drive, there are none to skip.
- Power that does not wait for a tooth. Onyx says the hub carries your pedaling to the rear wheel instantly, for faster acceleration and more control. There is no gap between teeth to cross before it picks up.
- Silent coasting. Taking out the pawls also takes out the sound they make against the teeth, and removes the play that comes with them. The wheel coasts quietly.
Spank and Onyx custom wheel questions
Which Onyx hub fits my Spank rim?
The cards on this page start on the Onyx hub our customers build with each rim most often (Onyx MTB Centerlock). The builder lists every Onyx hub that fits your rim, in the drillings and brake types that match.
Do you build Spank rims on other hubs?
Yes. See our Spank custom wheel page for every hub that fits each Spank rim, or our Onyx custom wheel page for every rim on an Onyx hub.
Can you build with an Onyx hub or Spank rim I already own?
Yes. Choose the supply-your-own option in the configurator, ship it to us, and we will lace it into a new wheel with new spokes cut to the right length. You pay for the parts you need and the build labor.
How long will my wheel take?
Build time comes down to parts availability rather than bench time. Your estimated ship date is shown in the configurator before you check out, so you know the date before you pay.
Not sure what to pick? Email info@prowheelbuilder.com (fastest) or leave a voicemail on 470-253-0929. You will be talking to the people who build the wheels.
