Derby Wheels with Bitex Hubs
Custom Derby Wheels on Bitex Hubs
Pick a Derby rim we carry, put it on a Bitex hub, and we lace and true the wheel by hand in our Georgia shop.
Why build Derby rims on Bitex hubs:
- Made by specialists: Bitex hubs made in Bitex's family factory in Taichung, Taiwan
- Proven: Derby offers its 29 x 35i in a downhill layup rated for 300 pound riders; Bitex patented the hardened Gouge Guard splines that stop cassettes biting the freehub
- Built to last: Bitex freehubs and axle ends swap to follow your next drivetrain or frame; 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
Build your custom Derby wheel on Bitex hubs for:
Or start from the Bitex hub you want:
BX 106 Centerlock→BX 211 6-bolt→BX 212 Centerlock→FB MTF 6-bolt, front only→FB MTR 6-bolt, rear only→MTR 6-bolt, rear only→MTF 6-bolt, front only→
Or pick one of the 8 ready-made pairs below: each opens our custom wheel builder with the Derby rim and Bitex hub already chosen.
Gravel in depth
Derby Carbon BX 25i wheels on Bitex BX 106 hubs
Our gravel pick from the Derby and Bitex 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 Bitex BX 106 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.
- Axle ends that convert. Bitex lists quick release and 12mm thru-axle options on models like the MTR, and shows the axle and end cap changes in its videos. If your next frame uses a different standard, the wheel may be able to follow it.

Mountain in depth
Derby Carbon DH 40i wheels on Bitex BX 211 hubs
Our mountain pick from the Derby and Bitex 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 Bitex BX 211 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.
- Six pawls in two sets. Bitex's patented freehub splits its pawls into two groups of three that take turns meeting the ratchet teeth, so the gap between engagement points is half what it would be. The company says the larger pawls also carry more load.

Why the pairing, specs and FAQ
Custom hand built Derby wheels on Bitex 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 Bitex 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.
- Gouge Guard on the freehub. Steel cassette cogs tend to bite notches into an aluminum freehub, and those notches make the cassette hard to remove. Bitex patented three small hardened stainless splines that take that pressure instead, and it is the Anti-Bite label on our Shimano HG driver choice.
- Six pawls in two sets. Bitex's patented freehub splits its pawls into two groups of three that take turns meeting the ratchet teeth, so the gap between engagement points is half what it would be. The company says the larger pawls also carry more load.
- A freehub you can change later. Each model lists its own freehub bodies, such as Shimano, Campagnolo, XDR or XD, and Bitex publishes videos showing how to swap one. Moving to a new drivetrain can mean a new freehub body and not a new hub.

Derby and Bitex custom wheel questions
Which Bitex hub fits my Derby rim?
The cards on this page start on the Bitex hub our customers build with each rim most often (Bitex BX 106, Bitex BX 211). The builder lists every Bitex 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 Bitex custom wheel page for every rim on a Bitex hub.
Can you build with a Bitex 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.
