Derby Wheels with Paul Hubs
Custom Derby Wheels on Paul Hubs
Pick a Derby rim we carry, put it on a Paul hub, and we lace and true the wheel by hand in our Georgia shop.
Why build Derby rims on Paul hubs:
- Made by specialists: Paul hubs machined in Chico, California
- Proven: Derby offers its 29 x 35i in a downhill layup rated for 300 pound riders; Paul made the first purpose-built single speed mountain bike hub in 1996
- Built to last: Paul's sealed bearings are user adjustable; 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 Paul FHub Disc hubs
Our gravel pick from the Derby and Paul 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 Paul FHub Disc hubs (front wheel) 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.
- Less stress at the spoke head. Spoke holes are chamfered, and on the WORD the flanges are canted toward the rim. Paul does this to reduce stress on the head and elbow of each spoke.

Mountain in depth
Derby Carbon DH 40i wheels on Paul FHub Disc hubs
Our mountain pick from the Derby and Paul 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 Paul FHub Disc hubs (front wheel) 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.
- The hub that started single speed mountain bikes. Paul introduced the Wacky One-Speed Rear Device in 1996 and calls it the first purpose-built single speed mountain bike hub. Paul says its 52mm chainline is a standard that continues today.

Why the pairing, specs and FAQ
Custom hand built Derby wheels on Paul 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 Paul 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.
- The hub that started single speed mountain bikes. Paul introduced the Wacky One-Speed Rear Device in 1996 and calls it the first purpose-built single speed mountain bike hub. Paul says its 52mm chainline is a standard that continues today.
- A rear wheel with no dish. On the WORD, Paul spread the flanges as far as it could while leaving room for freewheel threads. Both sides of the wheel can then be built alike, which Paul says makes a strong dishless wheel.
- An axle that runs from dropout to dropout. The disc hubs use an interchangeable 7075 aluminum axle in quick release, bolt-on or thru axle form, not end caps that can fall off when the wheel comes out. Change forks later and you change the axle, not the hub.

- Tires. Every Derby rim on this page is hookless, so choose a tire its maker rates for hookless rims.
Derby and Paul custom wheel questions
Which Paul hub fits my Derby rim?
The cards on this page start on the Paul hub our customers build with each rim most often (Paul FHub Disc). The builder lists every Paul 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 Paul custom wheel page for every rim on a Paul hub.
Can you build with a Paul 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.
