Spank Wheels with SON Hubs
Custom Spank Wheels on SON Hubs
Pick a Spank rim we carry, put it on a SON hub, and we lace and true the wheel by hand in our Georgia shop.
Why build Spank rims on SON hubs:
- Made by specialists: Spank rims made in Spank's own factory, Fratelli Industries, on SON hubs made in Tuebingen, Germany
- Proven: Spank's Vibrocore damps trail vibration and raises fatigue life; SON hubs run many tens of thousands of kilometers with no adjustment
- Built to last: SON backs every hub with a five-year warranty; Spank shotpeens the surface rather than machining metal away
- Laced and trued by hand, one wheel at a time, in our Georgia shop
- In depth below: Spike Race 33 gravel · 359 Spike Vibracore mountain

Gravel in depth
Spank Spike Race 33 wheels on SON Delux Disc hubs
Our gravel pick from the Spank and SON 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 SON Delux Disc hubs (front wheel) 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.
- Bearings that need nothing from you. SON uses SKF ball bearings sealed on both sides and lubricated for life, which it says run many tens of thousands of kilometers with no adjustment. All SON hubs carry a five-year warranty.

Mountain in depth
Spank 359 Spike Vibracore wheels on SON 28 Disc 6-bolt hubs
Our mountain pick from the Spank and SON 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 SON 28 Disc 6-bolt hubs (front wheel) 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 generator tuned to how you ride. The SON 28 is SON's all-purpose choice, with strong output even at low speed, including for charging devices. The SONdelux is lighter with lower mechanical resistance for fast riders and small wheels, and it gives up some output below 20 km/h.

Why the pairing, specs and FAQ
Custom hand built Spank wheels on SON hubs
Every pair on this page is in our builder today, with a rim and hub that fit each other. 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 SON 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 generator with its coil in the center. SON uses a claw-pole generator with the coil placed centrally and carefully made sheet metal parts, which it says keeps losses low when the lights are off. It works without gears or contact, so SON says the generator itself does not wear.
- Pressure compensation to keep water out. SON credits this system, which ends in the axle bore, for its protection against water getting in. It is why SON asks you not to grease the skewer shaft and to keep strong jets of water off the hub.
- Bearings that need nothing from you. SON uses SKF ball bearings sealed on both sides and lubricated for life, which it says run many tens of thousands of kilometers with no adjustment. All SON hubs carry a five-year warranty.
Spank and SON custom wheel questions
Which SON hub fits my Spank rim?
The cards on this page start on the SON hub our customers build with each rim most often (SON Delux Disc, SON 28 Disc 6-bolt). The builder lists every SON 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 SON custom wheel page for every rim on a SON hub.
Can you build with a SON 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.
