Nextie Premium RGX carbon wheelset
A complete wheelset built around the Premium RGX rim. Nextie laces a pair of Premium RGX rims to its own Rollingstar II Road or Rollingstar III Road hubs with Sapim spokes and black alloy nipples, in 3 sizes (45-65mm deep), tensions and trues both wheels in its Xiamen factory and ships the pair complete.
ProWheelBuilder is an independent wheel builder in Georgia and a Nextie dealer, not the manufacturer: we sell the wheelset and check your axle, freehub and size choices before the order goes in.
Building your pair
Every Nextie Premium RGX wheelset is sold as a front and rear pair, and the two wheels do not have to match. Pick the front depth and the rear depth separately: a shallower front for crosswinds with a deeper rear for speed is the common choice, and a matched pair is one click. The front is never deeper than the rear, so a deeper front with a shallower rear is not built. The rear follows the front until you choose a different one. Both wheels share the hub set, so they share the drilling; a depth that is not made in the drilling you picked is struck through.
Sizes, wheelset weights and prices
Wheelset weight is the complete pair as built: both rims, spokes, nipples and the hub set, from the lightest spoke and hub choice to the heaviest. Prices are for a matched pair on the least expensive hub; mixed front and rear pairs are priced from the two rims you choose.
| Size | Wheel | Inner width | Depth | Tire range | Rim weight | Wheelset weight | Drilling | Wheelset price |

| RGX 45 | 700c | 38.0mm | 45mm | 50-75mm | 440g | 1333-1453g | 24H | from $1015 |
| RGX 55 | 700c | 38.0mm | 55mm | 50-75mm | 480g | 1413-1533g | 24H | from $1055 |

The rim
The RGX has the widest gravel bed Nextie makes: 38mm inside, for the biggest gravel and monster-cross tires. It comes in 45, 55 and 65mm depths from 440 grams, in the Premium edition with a three-year warranty.
Premium is Nextie's balanced edition: a T700 and high-modulus T800 carbon mix, an independent spoke-bed mold for consistent spoke-hole thickness, roundness and flatness within 0.20mm, and a 3-year factory warranty - stiffness, deflection control and weight in balance. No Premium gravel size carries its own UCI certificate yet; the approvals listed on the rim page are on Nextie's Supreme road and gravel rims, which go through the same factory protocol. The Nextie Premium RGX rim page carries Nextie's published lab results, test videos and certificates in full.
Hubs, spokes and drive
Hub choices: Nextie Rollingstar II Road 12x100 / 12x142 24H, Centerlock rotor mount; Nextie Rollingstar III Road 12x100 / 12x142 24H, Centerlock rotor mount. The hub sets the drilling, 24H, and both wheels use the same set.
Spokes are Sapim: the round Race (2.0/1.8mm double-butted) for durability, or the bladed CX-Ray for less weight and drag, both with black alloy nipples. Freehub bodies: Shimano Road (HG), Shimano Micro Spline Road 12S, SRAM XDR, Campagnolo N3W 13S.
Finish: matte or glossy carbon. Decals: None, Outline White, Solid Black, Glossy Solid Black, Solid Chromium. Bead: Hooked or Hookless.

Value
Wide carbon gravel rims are a small market, and the few big-brand options are priced accordingly.
Ordering and lead time
Nextie builds each wheelset to order in Xiamen, so allow roughly two weeks for the build plus transit. The price at the top of the page is the complete wheelset as configured. Want a single wheel, a different hub, other spokes, or a wheel laced here in Georgia? Build it in the Custom Wheel Program, which opens with the Nextie Premium RGX rim already selected.
Warranty
Manufacturer's warranty. Nextie warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by Nextie and can change without notice, so ask us and we will confirm the current terms before you buy.
ProWheelBuilder. These wheels were built at the factory, not on our bench, so it is the maker's warranty above that stands behind them - our own one-year wheel warranty covers wheels we lace ourselves. If you do need to claim, we will deal with the manufacturer for you.
Full terms are on our Policies & Warranty page.
Nextie Premium RGX wheelset questions
Will an RGX take a mountain bike tire?
Nextie lists tires from 50 to 75mm, which covers big gravel tires and 2.0 to 2.25in mountain bike tires. Check your frame's tire clearance first.
Is the RGX tubeless-ready?
Yes. We tape it and fit a valve when you choose the tubeless option in the build.
Can I run a different depth front and rear on the Nextie Premium RGX wheelset?
Yes. Pick the front and rear size separately; the price is the two rims you chose plus the build, and a matched pair costs exactly what it always has. Both wheels share one drilling because they share the hub set.
Can I buy one Premium RGX wheel on its own?
Not from this page: the factory-built wheelset is sold as a pair. A single front or rear wheel on this rim can be built in the Custom Wheel Program.
Which hub should I choose?
Rollingstar II is the value choice; Rollingstar III is the lighter hub set, about 60 grams lighter for the pair. Each hub is drilled one way, so the drilling and the hub are chosen together.
Is ProWheelBuilder the manufacturer of the Nextie Premium RGX?
No. Nextie designs and manufactures the rims and hubs and builds this wheelset in Xiamen. ProWheelBuilder is an independent wheel builder in Georgia and a Nextie dealer: we sell it, check your choices before the order goes in and handle any warranty claim.
