Derby Wheels with Onyx Hubs
Custom Derby Wheels on Onyx Hubs
Pick a Derby rim we carry, put it on an Onyx hub, and we lace and true the wheel by hand in our Georgia shop.
Why build Derby rims on Onyx hubs:
- Made by specialists: Onyx hubs machined in Minnesota
- Proven: Derby offers its 29 x 35i in a downhill layup rated for 300 pound riders; Onyx drives through a sprag clutch, with no teeth to skip
- Built to last: Onyx hubs coast silently, with no pawls to wear; Derby drills drain holes so water spins out instead of sitting in the rim
- Laced and trued by hand, one wheel at a time, in our Georgia shop
- In depth below: Carbon BX 25i gravel · Carbon DH 40i mountain

Gravel in depth
Derby Carbon BX 25i wheels on Onyx Vesper Centerlock hubs
Our gravel pick from the Derby and Onyx parts we build with. The Derby Carbon BX 25i is a hookless carbon rim, 25mm inside, 32.5mm deep, about 415 grams in 650b, sized for about 35 to 50mm tires. We lace it to Onyx Vesper Centerlock hubs in 28 hole.
- Ridges that hold the bead. A retention ridge forms a channel for the tire bead, which Derby says secures tubed and tubeless tires and prevents burping. A deep center channel eases mounting, and Derby says tubeless tires air up with a floor pump.
- 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.

Mountain in depth
Derby Carbon DH 40i wheels on Onyx Vesper Centerlock hubs
Our mountain pick from the Derby and Onyx parts we build with. The Derby Carbon DH 40i is a hookless carbon rim, 39.5mm inside, 31mm deep, about 565 grams in 29 inch, sized for about 2.8 to 3.0 inch plus tires. We lace it to Onyx Vesper Centerlock hubs in 32 hole.
- The same shape in different layups. The 29 x 35i comes in a trail layup at about 515 grams with a 225 pound rider limit, and a downhill layup at about 630 grams with a 300 pound limit. You choose how much strength to carry for how you ride.
- 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 Derby 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 Derby rims and Onyx hubs each bring
- Width was the starting point. Derby Rims began in 2012 after its founder found that 25mm carbon rims lost the stability and cornering traction of 30mm aluminum rims. The goal became a wider carbon rim that kept the low weight and added that traction back.
- Thick hookless walls. Derby rims use hookless walls 3mm thick in a parabolic profile, and Derby says the shape was chosen for load-bearing strength. Because there is no separate hook, the thick wall itself holds the tire.
- Ridges that hold the bead. A retention ridge forms a channel for the tire bead, which Derby says secures tubed and tubeless tires and prevents burping. A deep center channel eases mounting, and Derby says tubeless tires air up with a floor pump.
- 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.
Check before you order
- Tires. Every Derby rim on this page is hookless, so choose a tire its maker rates for hookless rims.
Derby and Onyx custom wheel questions
Which Onyx hub fits my Derby 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 Derby rims on other hubs?
Yes. See our Derby custom wheel page for every hub that fits each Derby rim, or our Onyx custom wheel page for every rim on an Onyx hub.
Can you build with an Onyx hub or Derby 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.
