Chromag Wheels with Onyx Hubs
Custom Chromag Wheels on Onyx Hubs
Pick a Chromag rim we carry, put it on an Onyx hub, and we lace and true the wheel by hand in our Georgia shop.
Why build Chromag rims on Onyx hubs:
- Made by specialists: Onyx hubs machined in Minnesota
- Proven: Chromag says the BA30 v2 takes 20 percent more impact than the original at the same weight; Onyx drives through a sprag clutch, with no teeth to skip
- Built to last: Onyx hubs coast silently, with no pawls to wear; Chromag welds and grinds the seam so the joint is the strongest part of the rim
- Laced and trued by hand, one wheel at a time, in our Georgia shop
- In depth below: BA30 V2 mountain

Or pick one of the 2 ready-made pairs below: each opens our custom wheel builder with the Chromag rim and Onyx hub already chosen.
Mountain in depth
Chromag BA30 V2 wheels on Onyx Vesper Centerlock hubs
Our mountain pick from the Chromag and Onyx parts we build with. The Chromag BA30 V2 is a hooked aluminum rim, 30mm inside, 19mm deep, about 640 grams in 29 inch, sized for about 2.3 to 2.6 inch tires. We lace it to Onyx Vesper Centerlock hubs in 32 hole.
- A bead wall built for rock strikes. Chromag concentrates material in the bead wall, where impacts land, and rounds the outer edge to reduce tire damage under compression. The aim is better dent resistance and tire retention, and fewer pinch flats.
- Standard spokes and rotor mounts. For all the unusual drive, these are J-bend hubs that take standard J-bend spokes, the easiest kind to find anywhere. Vesper and MTB disc models come in Centerlock and 6-bolt.

Why the pairing, specs and FAQ
Custom hand built Chromag wheels on Onyx 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 Chromag rims and Onyx hubs each bring
- A bead wall built for rock strikes. Chromag concentrates material in the bead wall, where impacts land, and rounds the outer edge to reduce tire damage under compression. The aim is better dent resistance and tire retention, and fewer pinch flats.
- A welded and ground seam. Both rims are fusion welded at the joint and then ground smooth, and Chromag says that makes the seam the strongest part of the rim. A full weld also keeps the joint airtight for tubeless.
- Nipple beds angled to the spoke. Chromag's oriented bed lines up each nipple seat with the angle of its spoke. Chromag says this reduces stress on the nipple and spoke, which makes for a stronger wheel.
- 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.
Chromag and Onyx custom wheel questions
Which Onyx hub fits my Chromag rim?
The cards on this page start on the Onyx hub our customers build with each rim most often (Onyx Vesper Centerlock). The builder lists every Onyx hub that fits your rim, in the drillings and brake types that match.
Do you build Chromag rims on other hubs?
Yes. See our Chromag custom wheel page for every hub that fits each Chromag rim, or our Onyx custom wheel page for every rim on an Onyx hub.
Can you build with an Onyx hub or Chromag 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.
