Derby Wheels with SON Hubs

The ProWheelBuilder workshop

Custom Derby Wheels on SON Hubs

Pick a Derby rim we carry, put it on a SON hub, and we lace and true the wheel by hand in our Georgia shop.

Why build Derby rims on SON hubs:

  • Made by specialists: SON hubs made in Tuebingen, Germany
  • Proven: Derby offers its 29 x 35i in a downhill layup rated for 300 pound riders; SON hubs run many tens of thousands of kilometers with no adjustment
  • Built to last: SON backs every hub with a five-year warranty; 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

Or pick one of the 8 ready-made pairs below: each opens our custom wheel builder with the Derby rim and SON hub already chosen.

Gravel in depth

Derby Carbon BX 25i wheels on SON Delux Disc hubs

Our gravel pick from the Derby and SON 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 SON Delux 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.
  • 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

Derby Carbon DH 40i wheels on SON 28 Disc 6-bolt hubs

Our mountain pick from the Derby and SON 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 SON 28 Disc 6-bolt 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.
  • 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.

More about Derby and SON wheels

Why the pairing, specs and FAQ

Custom hand built Derby 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 Derby rims and SON 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 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.

Derby and SON custom wheel questions

Which SON hub fits my Derby 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 Derby rims on other hubs?

Yes. See our Derby custom wheel page for every hub that fits each Derby rim, or our SON custom wheel page for every rim on a SON hub.

Can you build with a SON 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.
