Reserve Wheels with Onyx Hubs

The ProWheelBuilder workshop

Custom Reserve Wheels on Onyx Hubs

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

Why build Reserve rims on Onyx hubs:

  • Made by specialists: Onyx hubs machined in Minnesota
  • Proven: Reserve shaped its road rims from 1,500 miles of real-world wind data; Onyx drives through a sprag clutch, with no teeth to skip
  • Built to last: Onyx hubs coast silently, with no pawls to wear; Reserve repairs or replaces rims damaged by riding, for the life of the rim
  • Laced and trued by hand, one wheel at a time, in our Georgia shop
  • In depth below: 25 GR gravel · 30 HD Aluminum mountain · 34 TA road

Gravel in depth

Reserve 25 GR wheels on Onyx Vesper Centerlock hubs

Our gravel pick from the Reserve and Onyx parts we build with. The Reserve 25 GR is a hooked carbon rim, 25mm inside, 18mm deep, about 350 grams in 700c, sized for about 35 to 50mm tires. We lace it to Onyx Vesper Centerlock hubs in 24 hole.

  • Semi-hooked road beads. Reserve says hookless rims limit tire choice and pressure, while full hooks add weight and make tubeless tires harder to fit. Its road rims sit between the two, with no tire incompatibility and a 100 psi limit.
  • 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

Reserve 30 HD Aluminum wheels on Onyx Vesper Centerlock hubs

Our mountain pick from the Reserve and Onyx parts we build with. The Reserve 30 HD Aluminum is a hookless aluminum rim, 30mm inside, 22mm deep, about 580 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 warranty that covers riding damage. Reserve repairs or replaces, at its option, any of its rims damaged or destroyed by riding, for the life of the rim and for the original owner. On aluminum rims it names a dent that stops the rim holding air, seam separation and a crack at a spoke hole as covered.
  • 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.

Road in depth

Reserve 34 TA wheels on Onyx Vesper Centerlock hubs

Our road pick from the Reserve and Onyx parts we build with. The Reserve 34 TA is a hooked carbon rim, 22.8mm inside, 34mm deep, about 335 grams in 700c, sized for about 28 to 38mm tires. We lace it to Onyx Vesper Centerlock hubs (front wheel) in 24 hole.

  • Different rims front and rear. Crosswind on the front wheel affects steering, so a front rim such as the 34 is slightly shorter, wider and rounder. The rear sits partly sheltered by the frame and rider, so a rear rim such as the 37 is taller and narrower to cut drag.
  • Bearings chosen for low drag. Onyx fits premium-grade bearings front and rear, and credits them with very low rolling resistance on both wheels.

More about Reserve and Onyx wheels

Why the pairing, specs and FAQ

Custom hand built Reserve 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 Reserve rims and Onyx hubs each bring

  • A warranty that covers riding damage. Reserve repairs or replaces, at its option, any of its rims damaged or destroyed by riding, for the life of the rim and for the original owner. On aluminum rims it names a dent that stops the rim holding air, seam separation and a crack at a spoke hole as covered.
  • Wind measured on real roads. For what it calls Turbulent Aero, Reserve logged more than 1,500 miles of wind data across the USA and Europe with sensors on a scooter, then recreated those conditions in the wind tunnel. Earlier practice, it says, was mostly testing air from the front.
  • Different rims front and rear. Crosswind on the front wheel affects steering, so a front rim such as the 34 is slightly shorter, wider and rounder. The rear sits partly sheltered by the frame and rider, so a rear rim such as the 37 is taller and narrower to cut drag.
  • 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. The 25 GR, 34 TA, 37 TA, 34 TA SL, 37 TA SL, 40 GR, 42 TA SL, 44 GR, 49 TA SL, 77 TA, 88 TA and 30 GR Aluminum are hooked; every other Reserve rim on this page is hookless, so choose a tire its maker rates for hookless rims.

Reserve and Onyx custom wheel questions

Which Onyx hub fits my Reserve 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 Reserve rims on other hubs?

Yes. See our Reserve custom wheel page for every hub that fits each Reserve rim, or our Onyx custom wheel page for every rim on an Onyx hub.

Can you build with an Onyx hub or Reserve 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.
